Embodiment Construction

[0011] A device for reciprocating and rotating motion used in oil seal experiments, refer to figure 1 , the left support 3 and the right support 11 are respectively fixed on both sides of the base 12, the left end of the experimental shaft 2 is installed in the left support 3 through a bearing, and the end surface of the experimental shaft 2 passing through the left support 3 and the eccentric cam 1. The outer cylindrical surface fits tangentially. The axis of the eccentric hole of the eccentric cam 1 coincides with the axis of the external power. The external power drives the eccentric cam 1 to rotate. The right end of the experimental shaft 2 is provided with a spiral groove 7. The pressing column 9 that has boss is connected, and the right end of pressing column 9 is installed in the right support 11 by bearing and is positioned by nut, and the compression spring 10 is set on the pressing column 9 between boss and right support 11, The head of the guide column 8 fixed on th...

Abstract

The invention discloses a device for realizing reciprocating and rotating motion for an oil seal experiment. A medium cavity is formed in the inner side of a left support; the medium cavity is provided with an oil seal bottom hole used for installing an oil seal to be tested. An experiment shaft penetrates through an oil seal to be tested which is arranged on the oil seal bottom hole; the left endof the experiment shaft is arranged in the left support through a bearing; the end surface of the experiment shaft penetrating through the left support is attached and tangent to the outer cylindrical surface of an eccentric cam; external power drives the eccentric cam to rotate; a spiral groove is formed outside the right end of the experiment shaft; the right end of the experiment shaft is connected with a pressing column provided with a boss; the right end of the pressing column is mounted in a right support through a bearing and is positioned through a nut; the compression column betweenthe boss and the right support is sleeved with a compression spring, and the head of a guide column fixed to the base extends into a spiral groove of the spiral shaft groove. The device has the advantages that the eccentricity of the eccentric cam and the characteristics of the spiral groove are used for achieving rotation and reciprocating motion, the structure is simple, and the device can meetthe experiment requirements of oil seals of different specifications.

Description

technical field [0001] The invention belongs to the technical field of oil seal testing experimental equipment, in particular to a device for realizing reciprocating and rotating motions used in oil seal testing. Background technique [0002] At present, in the field of oil seal testing experiments, most of the test benches basically only do rotation or reciprocating motion, and shaft seals can only be used to test rotation or reciprocating motion. Complicated and expensive. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies of the prior art and provide a realization of the oil seal experiment that utilizes the eccentricity of the eccentric cam and the characteristics of the spiral groove to realize the rotation and reciprocating motion, has a simple structure, and can adapt to the requirements of oil seal experiments of different specifications. Devices for reciprocating and rotating motion. [0004] The purpose of the...
