Questions about reducers and stepless speed regulators

1.Why do you need to add engine oil?

Answer: engine oil, mechanical oil, is lubricating oil, function: 1, the formation of oil film in the gear meshing part, so that the meshing gear is not in direct contact, due to the theory of 2 gears meshing at one point, but, in practice, processing error and other factors, so that the 2 meshing gears have a sliding amount at the moment of meshing, if there is no oil film isolation, so that the metal is in direct contact, there will be serious wear, wear and tear, it will produce a lot of heat, the transmission efficiency is reduced, the heat generated will make the gear glued, pitting, etc., Cause the failure of the gear,,, by adding lubricating oil, produce an oil film on the gear, hinder the direct contact of the gear, and at the same time, the lubricating oil can take away the heat generated by the gear meshing, which has the effect of cooling, and will also wash away the wear and tear iron filings produced by the gear meshing, and play a cleaning role.

2.The principle of the reducer is mainly to reduce the speed and increase the output torque through gear meshing, of course, there are special planetary reducers, cycloid reducers, three-ring reducers, etc., you can search for it, a lot of information,,, as for the stepless speed regulator, it is to integrate a stepless speed regulation device in the reducer, mainly the friction disc type, and adjust the output speed by adjusting the contact area of the two parts of the friction plate.

3.The oil filler is generally at the highest point of the reducer, and some are breathable bolts that double as oil fillers, which are used for refueling after unscrewing the breathable plugs, and the oil fillers of the reducer are generally observation windows, and the oil fillers of other small geared motors have screw plugs, and the holes after unscrewing the screw plugs are used for refueling.

Summary. Qinqin is happy to answer for you: the speed regulation of the continuously variable speed reducer needs to be realized by adjusting the speed ratio of the reducer.

The specific steps are as follows:1Turn on the power of the reducer and pair the transmission reducer nut shaft with the power shaft.

2.According to the instruction manual provided by the manufacturer, find the gear ratio range of the reducer and determine the gear ratio value that needs to be set. 3.

Manually rotate the speed-regulating handwheel of the reducer to keep the reducer in the lowest speed. 4.Manually rotate the speed adjustment handwheel of the reducer, and adjust it continuously to gradually reach the required speed ratio value.

In the adjustment process, it is necessary to pay attention to the control of the rotation direction and speed of the handwheel, so as to avoid adverse effects caused by over-adjustment or under-adjustment. 5.After determining the required gear ratio, tighten the handwheel to ensure that the speed regulation of the reducer is in a stable state, and then turn off the power supply.

CV (continuously variable) speed regulation is composed of two sets of gears or pulleys that can change the diameter, connected by a chain or belt, and the gear ratio is controlled by changing the diameter of the gear or pulley. Due to the physical limitations of belts and chains, it cannot be used in engines with high torque (although it has been developed to withstand continuously variable transmissions), which are commonly found in scooters (belt drive), small cars (chain drive), and go-karts (belt drive).

Advantages: no shift action, convenient, no frustration of shifting, high transmission efficiency (much higher than automatic transmission (about 85%), close to manual transmission), so fast acceleration and low fuel consumption.

Disadvantages: The failure rate is relatively high, the cost is relatively high, and it cannot be used in high-output engines.

The first stage of the reducer is the cone disc friction transmission, when the center distance of the two friction wheels changes, the reduction ratio changes accordingly, and the stepless speed regulation is realized. Because it is a friction transmission, the reduction ratio is not constant when the load changes.

Stepless stepless is no step, so the speed ratio of this reducer is certain.

The continuously variable speed mechanism does not have an accurate transmission ratio. The manual transmission or automatic transmission has a defined gear ratio. However, the CVT is not geared, but relies on steel belts to achieve speed transmission through two front and rear cone drums.

The higher the engine speed, the ball in the input drum moves to the outer ring of the drum due to centrifugal force, thereby driving the steel belt to move to the outer ring of the input drum. The length of the steel belt is certain, if the end of the input drum is turned to the outer ring, then the output drum must be relatively compressed to the inner ring. That is, the big wheel with the small wheel.

This makes it faster. If the throttle is small, the centrifugal force of the input drum is small, and the speed is reversed.

Therefore, the car with a continuously variable transmission is not running at low speeds, and it is more fuel-efficient to run at low speeds. Instead, keep the engine in the right speed range to get a more optimized gear ratio (uncertain ratio) to be more fuel-efficient.

Finally, the working radius of the friction between the planetary friction wheel and the driving wheel, the pressure plate, the fixed ring and the speed regulating cam is uniformly changed to achieve stable stepless speed change.

MB continuously variable transmission speed regulation mode:

1. Handwheel speed regulation: there are two kinds of fast and slow handwheels and pointer handwheels;

2. Equipped with right angle device speed regulation;

3. Electric speed regulation.

The taper driving wheel and pressure plate are pressed by a set of disc springs, and the input shaft is connected with the driving wheel by a key to form a compressed active device. The inner side of a group of planetary friction wheels with taper is sandwiched between the pressing driving wheel and the pressure plate, and the outer side is sandwiched between the fixed ring with taper and the speed-regulating cam, and forms a friction pair; When the pressing active device is running, the friction wheel does pure rolling, because the fixed ring and the speed regulating cam do not move, therefore, the friction wheel rotates at the same time as the rotation, and drives the planetary carrier to rotate through the central shaft and slider bearing of the planetary friction wheel.

Reducer parts machining center stock provides: gear processing, gear motor, worm gear, continuously variable speed change, gear commutator, worm gear reducer, screw lift, micro cycloid pinwheel reducer, precision planetary reducer, spiral bevel gear reducer, helical gear hard surface reducer, reducer parts processing.

If you need gear processing, worm gear and worm processing, rack, sprocket, timing pulley, nylon gear and other reducer parts processing, you can come to the drawings or real sample consultation, domestic imports can be processed.

In general, a continuously variable speed motor does not need a reducer because it can adjust its speed on its own. However, if there is a special requirement for stepless speed change, it is difficult to achieve it, and it is necessary to install a reducer.

For example, when the vehicle is climbing, the output characteristics of the continuously variable speed system are constant torque, and the slip rate is large, so the reducer needs to be decelerated to make the driven machine run better, and increase the torque of the torsion posture. After deceleration, the working status of the machine with low speed and high torque is realized to meet the needs of the work.
