Sealing performance testing machine for sealing ring of bearing

Abstract

The invention belongs to the technical field of sealing performance test of bearing sealing rings, and particularly relates to a sealing performance testing machine for a sealing ring of a bearing. The sealing performance testing machine for the sealing ring of the bearing is characterized in that a variable frequency motor drives a belt wheel to rotate; the belt wheel drives a workpiece shaft to rotate through a key joint; the workpiece shaft transfers kinetic energy to a core part tool wheel, so the requirement for a rotating speed needed by the test is met; a tested test sealing ring is mounted between the tool wheel and an outer tool ring; the test sealing ring consists of a sealing lip, a lock ring and a dustproof cover; an entire set of bearing does not need to be used for testing; tool parts simulate the inner and outer rings of the bearing for testing. The sealing performance testing machine for the sealing ring of the bearing is simple and compact in structure, and simple and convenient to operate; multiple types and multiple specifications of products can be detected by means of a tool wheel replacement method, and the machine is multifunctional; the tool wheel is low in weight and convenient to replace, and an entire set of bearing does not need to be used for testing, so the test cost is reduced; the occupation space is small, and the maintenance is convenient; a series of detection for temperature, rotating speed, pressure intensity and the like can be performed on the sealing ring.

Description

technical field [0001] The invention belongs to the technical field of testing the sealing performance of bearing sealing rings, and in particular relates to a testing machine for sealing performance of bearing sealing rings. Background technique [0002] At present, domestic performance testing machines for bearing sealing rings still can only simulate the ambient temperature, but cannot simulate the performance of the sealing ring in the rotating body. For example, ZWZ Group’s current test method for bearing sealing performance is: use the existing testing machine in the testing and testing center to conduct a complete set of tests on the bearings, and test two or four sets each time. However, it is impossible to conduct special test research on bearing sealing rings. , such as high and low temperature environment simulation test, high and low pressure test of sealed chamber, etc. The relevant foreign testing machine is to put the sealing ring on the shaft for testing, an...

Problems solved by technology

[0002] At present, domestic performance testing machines for bearing sealing rings still can only simulate the ambient temperature, but cannot simulate the performance of the sealing ring in the rotating body.

For example, ZWZ Group’s current test method for bearing sealing performance is: use the existing testing machine in the testing and testing center to conduct a complete set of tests on the bearings, and test two or four sets each time. However, it is impossible to conduct special test research on the bearing sealing ring , such as high and low temperature environment simulation test, high and low pressure test of sealed chamber, etc.

The relevant foreign testing machine is to put the sealing ring on the shaft for testing, the speed is not high, and it can only be tested for a specific sealing ring, and it is inconvenient to replace
