Detailed Description

The invention will be further described with reference to the drawings and the following examples, but the scope of the invention is not limited thereto.

As shown in fig. 1 and 2, a bearing product impact resistance testing machine comprises a traction device 5, a track 2, a magnetic attraction device 4, a box body 7 and a bearing 6, wherein the traction device 5 and the track 2 are fixed on a bottom plate 8; the magnetic attraction device 4 consists of a magnet and a winding, wherein the winding is wound on the magnet and is connected with a power supply; the traction device 5 comprises a driving motor 51, a steel wire rope 52 and a fixed pulley 53, the fixed pulley 53 is fixed at the upper end of the track 2, an output shaft of the driving motor 51 is connected with a roller, the steel wire rope 52 is wound on the roller, and the steel wire rope 52 penetrates through the fixed pulley 53 to drive a magnet. The two sides of the box body 7 are provided with slide blocks which can slide in the track 2; the weight 3 is arranged in the box body 7, and the box body 7 can be opened and is used for replacing the weight 3 with different masses; the bottom end of the box body 7 is connected with a flange bulge through a bolt. And a bearing mounting seat 1 is fixed on the bottom plate 8 right below the flange bulge, and the bearing mounting seat 1 is used for mounting a bearing 6. The material of the box 7 is metal. During the impact test, the lifting height of the box 7 can be controlled by the rotating speed of the driving motor 51, and different scales can be arranged on the track 2.

The utility model relates to a bearing product impact resistance testing machine's theory of operation does: before the test, a heavy object 3 with required mass is selected and placed in a box body 7, the driving motor 51 is controlled to rotate forwards, the steel wire rope 52 drives the magnet to gradually approach the box body 7, the winding is electrified, the box body 7 is attracted by the magnet, the driving motor 51 is controlled to rotate backwards, the steel wire rope 52 is retracted, the box body 7 gradually rises until the required height is met, the winding is powered off, the box body 7 freely falls along the track 2, then the bearing 6 at the bottom end is impacted, impact load is applied to the bearing 6, after the impact, the bearing 6 is taken down, whether the bearing 6 has slight retardation, obvious retardation, clamping, rotation incapability and other phenomena are detected, and whether cracks, fractures, fragmentation and other phenomena exist in the appearance of the bearing. In the process of impact, the weight of the heavy object 3 is continuously adjusted, the limit of the impact load which can be born by the bearing 6 is tested, and designers can be helped to deeply know the bearing characteristic of the bearing 6, so that the product is further optimized, the success rate of product development is improved, and the product has more competitive advantages.

The embodiment is a preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and any obvious improvement, replacement or modification which can be made by those skilled in the art without departing from the essence of the present invention belongs to the protection scope of the present invention.
