Joint bearing dust cover waterproof tester

Abstract

The invention provides a joint bearing dust cover waterproof tester comprising a swing mechanism, a long shaft, a supporting base, a short shaft, a workpiece fixing plate, a slide rod and a swing plate. The swing mechanism is connected with one end of the long shaft and the long shaft is enabled to rotate around the axis in a reciprocating way through the swing mechanism. The other end of the longshaft is installed on the experiment joint bearing inner race. An installing base is fixed on the workpiece fixing plate. The experiment joint bearing outer race is installed in the installing base.One end of the short shaft is supported by the supporting base. The swing plate is installed on the other end of the short shaft. The joint bearing is embedded in the swing plate. One end of the sliderod penetrates into the joint bearing, and the other end of the slide rod and the long shaft are fixed. The swing plate is enabled to rotate around the axis of the short shaft in a reciprocating waythrough reciprocating rotation of the long shaft. The workpiece fixing plate and the swing plate are connected. The simple mechanism can be used, and one micro-motor and the connecting rod mechanism are applied to simultaneously drive the product to perform circumferential and left and right swinging.

Description

technical field [0001] The invention relates to the technical field of joint bearings, in particular to a waterproof testing machine for dust-proof covers of joint bearings. Background technique [0002] Spherical joint bearings are widely used in various fields. In some special working conditions or environments such as mud or water, in order to protect the internal working surface from being eroded and dirty by mud, it can still maintain a good working condition and extend the service life of the product. Due to the long service life, the sealing cover is often used to protect the working surface. Therefore, the sealing design of the dust cover directly determines the service life of the product. The most effective way to judge the sealing effect of the dust cover on the product is to simulate the real working environment of the product. The results of the experiment are convenient for the designer to verify and improve the design. [0003] It is known that the price of ...

Problems solved by technology

[0003] It is known that the price of testing machines with similar functions on the market is mostly around 100,000 yuan, which is relatively high. This type of testing machine usually uses two servo or stepping motors to drive the product ball head to swing left and right and the shell to move circularly. The test conditions of this product, combined with the needs of our company, comprehensively consider the following shortcomings of this equipment: complex structure, large footprint, high procurement cost, long procurement cycle, troublesome use and operation, etc. Generally speaking, it is suitable for various tests. In terms of conditions, the price / performance ratio may be more advantageous, but for our product with a single test condition, the price / performance ratio is very low, which will greatly increase the cost of the product
