How to use spiral bevel gears? What is the definition of spiral bevel gears and spiral bevel gears?

The tooth shape of the spiral bevel gear is arc shape, and it is generally tapered, like a bevel shape, so it is called a spiral bevel gear. Spiral bevel gear is a kind of transmission parts that can be driven smoothly and with low noise according to a stable transmission ratio, and has different names in different regions, also known as spiral bevel gear, arc bevel gear, arc bevel gear, spiral bevel gear, etc. The spiral bevel gear transmission has high efficiency, stable transmission ratio, large arc overlap coefficient, high bearing capacity, smooth transmission, reliable work, compact structure, energy saving and material saving, space saving, wear resistance, long life and low noise.

Among all kinds of mechanical transmissions, the transmission efficiency of spiral bevel gears is the highest, which has great economic benefits for all kinds of transmissions, especially high-power transmissions; When transmitting the same torque, the transmission pair of the transmission parts required is the most space-saving, and the space size required is smaller than that of the belt and chain drive; The transmission ratio of spiral bevel gears is permanently stable, and the stability of the transmission ratio is often the basic requirement for transmission performance in the transmission of various mechanical equipment; Spiral bevel gears work reliably and have a long life.

The size of the spiral bevel gear is 10mm-1600mm, the module is 1-36, and the accuracy level of the spiral bevel gear is GB5-GB8. According to the different design methods, processing methods, and processing equipment of spiral bevel gears, spiral bevel gears can be divided into German Klingenberg spiral bevel gears, American Gleason spiral bevel gears, Swiss Olympon spiral bevel gears, commonly known as Klingenberg spiral bevel gears, Gleason spiral bevel gears and Olympon spiral bevel gears. There are some subtle differences between these different types of helical bevel gears, but there are many similarities in the main parameters.

According to the different application environment of spiral bevel gear, various parameters are also very different, according to the different use environment, spiral bevel gear can be divided into centrifugal separator series spiral bevel gear, vertical coal mill spiral bevel gear, textile machinery series spiral bevel gear, reducer series spiral bevel gear, automobile transmission series spiral bevel gear, rolling machinery series spiral bevel gear, mining machinery series spiral bevel gear, wheel loader series spiral bevel gear, lateral mixer series spiral bevel gear, DCY reducer spiral bevel gear, DBY reducer spiral bevel gear, universal milling head spiral bevel gear, wire drawing machine series spiral bevel gear, cement vertical mill spiral bevel gear, oilfield drilling rig series spiral bevel gear, construction machinery series spiral bevel gear, high-frequency welded pipe spiral bevel gear, stainless steel welded pipe spiral bevel gear, pipe making machinery spiral bevel gear, cold forming machine series spiral bevel gear, hard tooth surface spiral bevel gear and other series of spiral bevel gear.

Spiral bevel gears are widely used in oilfield petrochemical machinery, various machine tools, various machining equipment, engineering machinery, metallurgical equipment, rolling machinery, mining machinery, coal mining machinery, textile machinery, ship machinery, shipbuilding industry, aerospace, forklifts, elevators, reducers, aircraft manufacturing and many other industries.

1. The spur bevel gear is the most basic bevel gear, which is simple to process, but the transmission accuracy is too poor, the instantaneous transmission ratio is not accurate, and it is only used as a general German change of direction transmission, and the speed and transmission ratio requirements are not strict mechanisms, such as the lifting of the bull head planer workbench, the operating shaft, etc., which is suitable for low-speed mechanisms.

2. Helical bevel gear is a modified type made on the basis of spur bevel gear, compared with some shortcomings of spur bevel gear, some shortcomings have been improved, such as: the instantaneous transmission ratio is relatively more accurate, the transmission accuracy is higher, and the transmission efficiency is higher than that of spur bevel gear.

3. The efficiency of the spiral bevel gear is the best, the performance parameters are the best in all aspects, the transmission shaft at the bottom of the car and the [tooth bag] of the rear axle (that is, the round thing in the middle of the rear axle), there is a set of spiral bevel gear pairs, and its performance is as follows

Advantages: high transmission efficiency, low friction resistance, accurate instantaneous transmission ratio, large transmission torque, especially suitable for high-speed transmission.

Disadvantages: high manufacturing cost, due to manufacturing and installation reasons, it is difficult to grasp the best degree of coincidence, good lubrication is required, and it is best to lubricate in an oil bath.

The tooth shape of the spiral bevel gear is arc shape, with helix angles, and the tooth surface shape is tapered (see figure).

Because the shape of the tooth surface of the spiral bevel gear is very similar to an umbrella, it is also called spiral bevel gear, arc bevel gear, arc bevel gear, arc bevel gear, etc.

The spiral bevel gear transmission has high efficiency, stable transmission ratio, large arc overlap coefficient, high bearing capacity, stable transmission, reliable work, compact structure, energy saving and material saving, space saving, wear resistance, long life and low noise. Among all kinds of mechanical transmissions, the transmission efficiency of spiral bevel gears is the highest, which has great economic benefits for all kinds of transmissions, especially high-power transmissions; When transmitting the same torque, the transmission pair of the transmission parts required is the most space-saving, and the space size required is smaller than that of the belt and chain drive; The transmission ratio of spiral bevel gears is permanently stable, and the stability of the transmission ratio is often the basic requirement for transmission performance in the transmission of various mechanical equipment; Spiral bevel gears work reliably and have a long life.

So you're talking about two names for the same gear.

There is also a kind of bevel gear or bevel gear (note: less helical two words) The fundamental difference between it and spiral bevel gear is that the tooth shape of the bevel gear has no helix angle, and the tooth shape of the spiral bevel gear has a helix angle (see figure).

Spiral bevel gears are widely used in oilfield petrochemical machinery, various machine tools, various machining equipment, engineering machinery, metallurgical equipment, rolling machinery, mining machinery, coal mining machinery, textile machinery, ship machinery, shipbuilding industry, aerospace, forklifts, elevators, reducers, aircraft manufacturing and many other industries. Spiral bevel gear is used in a variety of mechanical equipment, showing its excellent performance, and is deeply affected by aerospace equipment manufacturing plants, shipyards, construction machinery factories, metallurgical equipment factories, rolling spare parts factories, rolling machinery factories, rolling mills, metallurgical machinery factories, mining machinery factories, coal mining machinery factories, oilfield petrochemical machinery factories, textile machinery factories, machine tool factories, equipment companies, elevator companies, aircraft factories, reducer factories, coal mining machinery factories, light industry machinery factories, rolling mills, rolling equipment factories, Metallurgical equipment factories and other customers love.

There are accuracy grades with diameters of 10mm-1600mm, modules of 1-36, and spiral bevel gears.

There are GB5 - GB8 levels. According to the different design methods, processing methods, and processing equipment of spiral bevel gears, spiral bevel gears can be divided into German Klingenberg spiral bevel gears, American Gleason spiral bevel gears, Swiss Olympon spiral bevel gears, commonly known as Klingenberg spiral bevel gears, Gleason spiral bevel gears and Olympon spiral bevel gears. There are some subtle differences between these different types of helical bevel gears, but there are many similarities between the main ones.

According to the different application environment of spiral bevel gear, various parameters are also very different, according to the different use environment, spiral bevel gear can be divided into centrifugal separator series spiral bevel gear, vertical coal mill spiral bevel gear, textile machinery series spiral bevel gear, reducer series spiral bevel gear, automobile transmission series spiral bevel gear, rolling steel.

Machinery series spiral bevel gear, mining machinery series spiral bevel gear rental, wheel loader series spiral bevel gear, lateral mixer series spiral bevel gear, DCY reducer spiral bevel gear, DBY reducer spiral bevel gear, universal milling head spiral bevel gear, wire drawing machine series spiral bevel gear, cement vertical mill spiral bevel gear, oilfield drilling rig series spiral bevel gear, construction machinery con Weifeng series spiral bevel gear, high-frequency welded pipe spiral bevel gear, stainless steel welded pipe spiral bevel gear, Spiral bevel gears of pipe-making machinery, spiral bevel gears of cold forming machines, spiral bevel gears of hard tooth surfaces, etc.

The difference between the two transmissions:

1.In the transmission: the worm gear transmission is 90 degrees; The angle of the spiral bevel gear transmission can be as required.

Selected (typically 90 degrees).

2.In terms of transmission ratio: the transmission ratio of worm gear transmission is larger, and the transmission ratio of spiral bevel gear transmission.

If you want to increase it, the number of teeth will increase, and the volume will increase.

3.In terms of efficiency: the spiral bevel gear transmission is larger than the worm gear transmission, and the two transmissions have their own advantages and disadvantages, and they are selected according to the needs in the design.

Bevel gears, i.e. bevel gears, bevel gears. It is used for transmission between intersecting shafts.
