Long-acting temperature control friction coupler

Abstract

The invention provides a long-acting temperature control friction coupler. The long-acting temperature control friction coupler comprises a half coupling, a spline shaft, a friction ring, a positioning spline, a fixed bolt, an inner spline housing, a spline friction disk, and a pollution discharge radiating valve, wherein a working condition wedge block axially slides under the action of a centrifugal force to overcome resistance of a clamp spring to contact a left clutch and a right clutch with the friction ring, the spline friction disk heats up, the heat is transmitted to the working condition wedge block so that liquid in the working condition wedge block is expanded to push the piston to extend out, and meanwhile, the working condition wedge block backward moves under the action of a tension spring. According to the long-acting temperature control friction coupler, the friction disk and the friction ring in the long-acting temperature control friction coupler contact with each other in a double-faced mode, so that friction coefficients are increased, a temperature control system is reliable, the manufacture process is simple, the coupler is convenient to install, manufacturing technologies need not particular preciseness, and material costs are reduced; particularly, by means of a temperature control device, the condition of disposable friction materials is changed, a potential safety hazard that friction produces a high temperature is thoroughly eliminated, and any friction resisting material can be used, so that the effect of long-acting use can be achieved.

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...
