Embodiment Construction

[0025] according to Figure 1~7Detailed description of the specific structure of the present invention, the wear gap adjustment type ring block friction and wear testing machine includes a support 1, a power and transmission mechanism fixed on the support 1 and a material box 2 provided with a loading mechanism and a testing mechanism, and a measurement components such as control circuits. Among them, the power and transmission mechanism adopt the basic structure of the applicant's previous patent "a ring block friction and wear testing machine with intelligent control of speed". It includes a main shaft 16 assembled in a headstock 23 , a drive shaft 20 with a torque sensor 17 fixed thereon, an output shaft 19 of a servo motor 18 and the like connected on the same axis by a coupling 21 . The main shaft 16 in this embodiment is installed in the main shaft box 23, and is respectively sealed by the bearing end cover 22 and the mechanical seal 24, so as to ensure the working accu...

Abstract

The invention relates to a ring and block friction abrasion testing machine with an abrasion gap adjusting function. The problem that according to an existing friction abrasion machine, test ring and test block loading and gap adjustment cannot be achieved on one testing machine is solved. The ring and block friction abrasion testing machine comprises a machine base, a power and transmission mechanism fixed to the machine base, a material box provided with a loading mechanism and a testing mechanism and a measurement control loop. The ring and block friction abrasion testing machine is characterized in that the loading mechanism comprises an adjusting rod, a handle, a fine adjustment dial, a fixing base, a guide base with a clamp and guide rails, a stud section of the adjusting rod is matched with a threaded hole of the material box to form a spiral matched pair, the handle is fixedly connected to the top end of the adjusting rod, quantitative vertical loading and accurate adjustment of the gap between a test block and a test ring can be realized by rotating the handle, and the adjusting rod is fixed through the fixing device. The ring and block friction abrasion testing machine is reasonable in design, simpler in structure compared with other existing similar products and stable in operation, the test ring and the test block are convenient to load and unload, the gap is easy to adjust, spacing is accurate, and the reliability of test results conforming to actual working conditions is further improved.

Description

technical field [0001] The invention relates to a friction and wear testing machine, in particular to a wear gap adjustment ring block friction and wear testing machine for researching the tribological properties of rubber test blocks and metal test rings in a liquid medium containing solid particles. It can be used for the friction and wear test of rubber test block and metal test ring pair under dry friction, and can also be used for the friction and wear test of metal test ring and metal test block pair under liquid medium containing solid particles or dry friction. Background technique [0002] At present, liquid conveying equipment composed of rubber / metal pairs is widely used in crude oil mining and mine drilling, such as the metal rotor and rubber stator in the submersible screw pump, the rubber bushing and the metal screw of the screw mixed pump. With vice and so on. In the actual use process, the rubber bushing material is not only squeezed and sheared by solid par...
