A long-term temperature-controlled friction coupling

Abstract

The invention provides a long-acting temperature-control friction coupler, which includes a half-coupling, a spline shaft, a friction ring, a positioning spline, a fixing bolt, an inner spline sleeve, a spline friction disc, and a blowdown cooling valve. Under the action of centrifugal force, the shaped block slides axially to overcome the resistance of the circlip, so that the left clutch and right clutch contact the friction ring, the spline friction disc heats up, and the temperature is transmitted to the wedge-shaped block in the working condition, resulting in the wedge-shaped block in the working condition The liquid in the body expands, pushing the piston out, and under the action of the tension spring, the wedge-shaped block in the working condition moves backward; the friction disc inside the patent is in double-sided contact with the friction ring, which increases the friction coefficient, and the temperature control system is relatively reliable. It is simple, easy to install, and the production technology does not need to be particularly rigorous, which reduces the cost of materials, especially the temperature control device is used to change the current situation of one-time use of friction materials, and completely solve the safety hazard of high temperature caused by friction. Any friction-resistant material can be used , so as to achieve the effect of long-term use.

Description

technical field [0001] The invention relates to the field of mine electromechanical equipment, in particular to a long-term use temperature control friction coupler. Background technique [0002] At present, most of the existing electromechanical equipment such as scraper machines and belt conveyors for mining use hydraulic clutches or centrifugal friction to protect the motors. clutch. [0003] The hydraulic clutch is partially filled with a liquid medium in the inner cavity of the clutch. When the motor drives the clutch to rotate, the liquid medium impacts the turbine wheel blades of the clutch under the action of centrifugal force, thereby driving the output shaft to rotate. Since hydraulic clutches generally use oil or water as the force transmission medium, high temperatures are likely to occur during operation, causing oil or water to expand and boost pressure, resulting in the melting of the fusible plug set on the clutch housing, oil and water leakage, and eventual...
