specific Embodiment 2

[0051]The specific embodiment 2 of the bearing test device of the present invention, the difference between this embodiment and the above specific embodiment 1 is only that: the first heat dissipation channel is an oil lubrication oil circuit circulation channel, the bearing test device adopts oil lubrication, and the bearing test device uses oil lubrication Oil is medium oil cooling. When using oil lubrication, such as Figure 7 As shown, a plunger 10 is set in the through holes of the left and right bushes to block the through holes of the left and right bushes to reduce the number of inlets and outlets of the oil circuit. road. Keep the first heat dissipation channel unblocked. At this time, the lubricating oil circulates through the first heat dissipation channel. A cooling device can be installed in the oil tank of the lubricating oil to cool the circulating oil circuit to achieve the purpose of heat dissipation.

Abstract

The invention relates to the field of bearing test devices, and particularly relates to a bearing test device. The bearing test device comprises a test head component which comprises left and right bushings. The test head component also comprises a positioning bushing. The positioning bushing and the left and right bushings are coaxially fixed. Centering and positioning of the left and right bushings are performed through the positioning bushing in assembling so that the coaxiality of the left and right bushings can be guaranteed, then the coaxiality of left and right test bearings can be guaranteed and the coaxiality error of the left and right test bearings can be reduced. Compared with the present bearing test device that the left and right bushings are fixed on a base, the coaxiality of the left and right bushings can be guaranteed by the positioning bushing of the bearing test device so that the coaxiality precision of the left and right test bearings can be enhanced, and the problem that the present bearing test device cannot be suitable for miniature bearings can be solved.

Description

technical field [0001] The invention relates to the field of bearing testing devices, in particular to a bearing testing device. Background technique [0002] Miniature deep groove ball bearings refer to various deep groove ball bearings in the metric series with an outer diameter of less than 9mm. The main materials are carbon steel, bearing steel, stainless steel, plastic, ceramics, etc. It is suitable for high-speed and low-noise equipment such as various industrial equipment and small rotary motors. At present, the experimental research on miniature deep groove ball bearings is mainly the fatigue life and strengthening performance test. In order to analyze and continuously improve the design level and product quality of miniature deep groove ball bearings, it is necessary to specialize in the performance and performance of miniature deep groove ball bearings. The life test device is used to carry out experimental research and provide real and effective data reference fo...
