Description

High strength worm wheel is used for AGV speed reducer

Technical Field

The utility model relates to a it is big both to have bearing strength, and it is big to have the anti-overturning moment of bearing again, axial force is big, and can improve whole AGV speed reducer life's high strength worm wheel is used for the AGV speed reducer, belongs to the speed reducer field of making.

Background

CN207028846U, name "AGV with worm gear reduction gear", its constitution includes: frame body, drive wheel and worm gear reduction gear, characterized by: the driving wheel pass through the connecting rod and be connected with front side follow-up universal wheel, connecting rod intermediate position be provided with the bearing, the bearing in inserted the fixed axle, the both ends of fixed axle be connected to the frame body's both sides, the driving wheel with worm gear reduction gear connect, worm gear reduction gear be connected with the motor, the motor fix the inboard of connecting rod, the frame body the bottom respectively with the motor with worm gear reduction gear connect, the other end below of frame body be provided with rear side follow-up universal wheel, driving wheel and worm gear reduction gear connect. The method has the following defects: the worm gear reducer has the advantages of small bearing strength, small bearing anti-overturning moment, small axial force and short service life because of the existing known structure.

Disclosure of Invention

The design purpose is as follows: the defects in the prior art are avoided, and the high-strength worm gear which has the advantages of high bearing strength, large bearing anti-overturning moment, large axial force and capability of prolonging the service life of the whole AGV speed reducer is designed to be used for the AGV speed reducer.

The design scheme is as follows: in order to achieve the above design objectives. The utility model discloses in structural design, the worm wheel adopts the steel worm wheel in the AGV speed reducer to the one deck wearing layer has been put on the meshing surface of processing shaping back and worm wheel and worm, so not only can not influence its use accuracy, sets up the simple and easy bearing between worm wheel and flange moreover and the matching of wearing layer, makes the life of AGV speed reducer improve greatly. And (3) simulation test according to actual working conditions: the service life of the existing worm wheel on the market is more than 0.15mm when 500 thousands of revolutions are carried out; under same test condition, use the utility model discloses behind the high strength worm wheel, 500 ten thousand wearing and tearing volume of changeing are less than 0.008mm to make the bearing capacity of whole AGV speed reducer improve more than one time, make the performance of product more can satisfy the customer and use.

The technical scheme is as follows: the utility model provides a high strength worm wheel is used for the AGV speed reducer, and worm wheel meshing, the non-meshing position of worm wheel and worm is located the box, and the worm wheel has the one deck wearing layer for the surface of steel and worm wheel, is equipped with the bearing between worm wheel and the flange.

Compared with the prior art, the utility model, not only bearing strength is high, bears antidumping moment big, axial force is big, long service life moreover.
