Worm gear reducer testing device

Abstract

The invention relates to the technical field of reducer testing, in particular to a worm gear reducer testing device which comprises a support and a reducer body, the support is of an L-shaped structure, sliding rods are symmetrically and fixedly installed on the right side of the upper end face of the support in parallel, and a placement plate penetrates through and is slidably connected to the position, close to the right side, of the outer surface of the upper end of each sliding rod, the speed reducer body is vertically placed on the outer surface of the upper end of the placement plate, and a clamping mechanism is arranged on the left side of the speed reducer body; and the clamping mechanism comprises a clamping assembly, a concave frame and a sleeve, the clamping assembly comprises a first L-shaped movable rod and a second L-shaped movable rod, and the first L-shaped movable rod and the second L-shaped movable rod are movably connected through four sets of rotating rods. According to the invention, the speed reducer body can be quickly clamped during testing, automatic oiling is realized, dripping caused by manual pushing of the pipe body for oiling is reduced, and oil leakage conditions of the speed reducer body and the interior of the speed reducer body can be observed in real time, so that timely repair is facilitated, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of reducer testing, in particular to a testing device for a worm gear reducer. Background technique [0002] In order to improve the efficiency, the worm gear reducer generally uses non-ferrous metals as the worm wheel, and the worm is made of harder steel. Because it is a sliding friction transmission, it will generate high heat during operation; while the worm gear reducer is running Whether the outer casing leaks oil is an important indicator to determine the performance of the main body of the reducer. Since the reducer casing is thin, it is easy to collide with the outside when it is in use, causing the bottom to crack, which will cause the leakage of lubricating oil. The main body of the reducer is not sufficiently lubricated, which affects heat dissipation and use. [0003] The existing patent (notification number: CN111337247A) is a precision worm gear reducer testing equipment, including a bottom p...

Problems solved by technology

[0005] 1. For some worm gear reducers that have been put into use, it is necessary to detect their oil leakage during maintenance. However, when inspecting the main body of the reducer, first of all, the main body of the reducer must be completely clamped to maintain its detection. stability, but the clamping process of the above-mentioned invention is cumbersome and cannot quickly clamp the main body of the reducer. The operation process is complicated, time-consuming and labor-intensive, and affects the detection efficiency;

[0006] 2. The precision worm gear reducer testing equipment is aimed at testing the reduction ratio, operating temperature, amplitude and noise level. However, the above test is based on the normal state of the reducer body, and the test results are open to question; while the above test is being carried out If there is oil leakage inside the main body of the reducer, it will affect the working temperature of the main body of the reducer. Generally, when adding lubricating oil to the inside of the reducer, it is generally added manually The method is not only time-consuming and labor-intensive, but also easy to cause dripping of lubricating oil. When repairing the worm gear reducer that has been used for a long time, due to long-term use, the surface is mixed with oil and dust to form a thick dirt layer. During the maintenance process, it is difficult to observe well with the naked eye, and it is also impossible to visually see the oil leakage and damage of the main body of the reducer and its casing, which greatly reduces the test efficiency
