Description

Technical Field

[0001] This utility model relates to the technical field of worm gear reducers, specifically to a worm gear meshing device inside a worm gear reducer. Background Technology

[0002] A worm gear reducer mainly consists of three basic structures: a housing, a worm gear, and bearings and shafts. The worm gear mechanism transmits motion and power between two intersecting shafts, acting as a speed converter to precisely reduce the motor's rotational speed to the required speed. When the worm gear is engaged, its principle is equivalent to helical transmission, with the two meshing surfaces in line contact. This results in smooth operation with minimal noise and high load-bearing capacity. However, if the meshing accuracy of the worm gear fails to meet requirements, it will affect the reducer's reduction ratio, reduce the smoothness of operation, and weaken the reducer's load-bearing capacity.

[0003] In traditional worm gear meshing quality testing devices, the specific operating procedure is as follows: First, a layer of colorant is applied to the surface of the worm gear, and then the worm gear is placed on a sleeve, with the worm as a standard part. The distance between the worm and the worm gear in the horizontal and vertical directions is adjusted by using handwheels installed in the horizontal and vertical directions to ensure that the worm gear meets the conditions for full meshing. Rotating the handwheel connected to the worm clamping device promotes the meshing of the worm gear. However, this method has drawbacks. The handwheel connected to the worm clamping device needs to be continuously rotated during operation to ensure that the worm gear is fully meshed. The rotation process relies on manual operation, which makes it difficult to maintain a uniform speed. This not only makes the operation inconvenient but also leads to low work efficiency.

[0004] Therefore, it is necessary to modify it by using a servo motor in conjunction with the connecting plate to precisely control the rotation speed of the connecting plate, so as to achieve the effect of uniform rotation of the worm gear, meet the detection effect of measuring the degree of meshing at different speeds, improve the efficiency of gear meshing quality detection, and overcome the disadvantage of the inconvenience of manual adjustment in the traditional method.

This device, through the cooperation of a servo motor and a connecting disc, precisely controls the rotation speed of the connecting disc, achieving uniform rotation of the worm gear. This satisfies the requirements for measuring the degree of meshing at different speeds, improving the efficiency of gear meshing quality testing. It overcomes the inconvenience of traditional methods involving manual adjustment, solving the problem of relying on continuous manual rotation of the handwheel to ensure full meshing of the worm gear, which not only makes it difficult to guarantee uniform rotation but also results in inconvenient operation and low work efficiency.
