How is the worm screw elevator constructed

It is a mechanism that transmits torque through worm gear deceleration and converts it into linear motion by the lead screw. The mechanism can realize the revocation of power self-locking in any position, and its main features are "safe and reliable" and "small power and large thrust".

Screw elevators can be widely used in machinery, metallurgy, construction, chemical industry, medical treatment, culture and health and other industries. It can accurately control and adjust the height of lifting or propulsion according to a certain program, which can be directly driven by electric motor or other power, or manually.

Worm gear screw lift.

It is a motion combination unit that skillfully combines worm gear reducer and lead screw nut pair. It can be used alone, or it can be quickly combined through the connecting parts like building blocks to realize the lifting, reciprocating, flipping and other movements of objects.

As a functional component, worm screw lifts have been widely used in all walks of life. For example: transmission devices and CNC actuators in the machinery industry; Roll motion devices in the metallurgical industry, ladle lifting and turning devices in steel mills, and motion transmission devices in places beyond the reach of people; Rolling stock industry vehicle lifting frame, large-scale flexible clamping, indexing tooling, welding robots, etc.; Lifting devices, automatic or remote control opening devices for large doors and windows in the construction industry; water conservancy and other industries with gate opening devices, radar and solar remote sensing devices; lifting devices for medical equipment, lifting stages and automobile manufacturing; as well as aerospace, defense and military transmission devices, etc.

In fact, worm screw lifts can be used almost anywhere mechanical displacement transmission is required.

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.

Hello dear! 1. It may be empty to check whether the valve on the nut elevator is smooth, whether the nut is well sealed, and whether the nut is installed correctly.

2. It may be poor lubrication: you can check whether the lubricating oil on the nut elevator has been replenished in time, whether there is excessive wear or corrosion, and replace the grease in time. 3. It may be that the nut bolt is stressed unevenly

After the nut is installed, you can check whether there is poor bolt tightening or loose nut. 4. It may be that the tension of the screw spring is incorrect: you can check whether the tensioning and mounting of the screw circulation mechanism is in a normal state, and whether the tensioning knob is adjusted according to the actual needs of the nut elevator to ensure that the screw spring plays a normal role.

Worm screw lift, also known as QWL lift, is widely used in machinery, metallurgy, construction, water conservancy equipment and other industries, with lifting, descending and propulsion with the help of accessories, flipping and various height position adjustments and many other functions. SWL worm gear screw elevator is a kind of basic lifting components, which has many advantages such as compact structure, small size, light weight, wide power source, no noise, easy installation, flexible use, multiple functions, many supporting forms, high reliability, and long service life.

1. When the pressure load of the worm gear screw elevator decreases, the lifting height can be increased accordingly.

2. When the worm screw elevator lifts different loads, the allowable torque, power and speed are also different, and the maximum power of different working duration rates is also different.

3. The working environment temperature of the worm gear screw lift: -20 -+80.

The worm gear screw elevator can be used alone or in combination, and can accurately control and adjust the height of lifting or propulsion according to a certain program, and can be directly driven by electric motor or other power, or manually. It is available in different structural and assembly forms, and the lifting height can be customized according to the user's requirements, and the device can be self-locking.

1. When the pressure load of the worm gear screw elevator decreases, the lifting height can be increased accordingly, 2. When the worm gear screw elevator lifts different loads, the allowable torque, power and speed are also different, and the maximum power of different working duration rates is also different, 3. The working environment temperature of the worm screw lift: -20 -+80.

1. Common normal inspection.

Determination of grade: grade 8 is the worst grade (rough rolling), grade 7 (fine rolling), and grade 6 or less needs to be further processed on the basis of rolling. Generally speaking, a maximum of 7 levels of inspection is sufficient.

Determine the number of cross gears: Check how many teeth the worm gear has before you can determine the "number of cross gears". Check the standard to find the test tolerance of the common normal. Determine the specifications for using the common normal micrometer.

2. Cumulative error of weekly sections.

It is placed vertically along the datum surface of the gear, and can be achieved by using double tops or one top and one clamp, or mandrel rods. Using a deflection meter, a dial gauge is added to the tangential plane of the worm gear to read out the tolerance value.

3. Adjacent and separated tooth errors.

Using the common normal micrometer test, at least 6 points on the circumference of the circle are removed to read the maximum value.

4. Runout inspection.

End face runout: It is placed vertically along the datum surface of the gear, and a double top or one top and one clamp are adopted. However, the dial gauge head is read out on the end face, please note that the gear has only one interview datum, which is usually a ground face.

Tooth top runout: put the test mandrel between any 2 teeth along the datum surface of the gear, read out the position of 12 points at the gauge head of the dial gauge, hit multiple points, and take the maximum value.

5. Inspection of the meshing area and tooth top circle.

A standard worm is made and inspected directly with a caliper.

Check the standard, and use red pill or green oil to check the contact area.

6. Position check.

Simulate the location of the work. Check the standard, and use red pill or green oil to check the position of contact. Worm gears in both directions must be checked in 2 directions.

For multi-headed worms, it is also necessary to mark them, and the worm should be rotated 180° to check again. The above is the inspection and testing method of the screw elevator provided by Luosheng electromechanical manufacturers, I hope it will be helpful to you, if you are interested in this product, you can ask Luosheng customer service about this product.

Worm transmission is a kind of transmission mechanism that transmits motion and power between the two axes of space staggered, and the angle of the two axes staggered can be arbitrary, and the commonly used is 90 °. This kind of transmission has the advantages of compact structure, large transmission ratio, stable transmission and reliable self-locking under certain conditions, and is widely used; Its disadvantages are low transmission efficiency and frequent consumption of non-ferrous metals.

Worm drives are usually used for reducers, but there are also individual machines that are used as speed-increasing devices. With the increase of machine power, a variety of new types of worm transmission have appeared in recent years, and the shortcomings of low efficiency are gradually improving. There is an introduction in the 38th issue of Luosheng Electromechanical**, and you can go in and take a look at the details.
