Abstract

The invention discloses a shaft end hydraulic band-type brake. The shaft end hydraulic band-type brake comprises a base, supporting frames, a guide mechanism, pressing rods, a pressing shaft, a pushing sleeve, an oil cylinder, braking mechanisms, a shell, a first liquid separation block, a first one-way valve, a temporary storage mechanism, an extrusion mechanism, a second one-way valve, a long-stroke electromagnet and a second liquid separation block; and during braking, annular electromagnets arranged in the braking mechanisms are energized and attract attraction sleeves, the long-stroke electromagnet pushes the extrusion mechanism to press non-Newtonian fluid into arc-shaped grooves, transient solid is formed due to the fact that the viscosity of the non-Newtonian fluid in the arc-shaped grooves is extremely high at the moment when brake pads make contact with a high-speed working shaft to brake and buffer vibration of the working shaft, and the non-Newtonian fluid cools the workingshaft until the working shaft is completely stopped along with reduction of the speed of the working shaft. The device is simple in structure, and the functions of braking, vibration buffering and cooling are achieved through the change of the viscosity of the non-Newtonian fluid, so that the service life of the brake pads is prolonged, working vibration is reduced, and high practicability is achieved.

Description

technical field [0001] The invention relates to a mechanical brake, in particular to a shaft end hydraulic brake. Background technique [0002] The hydraulic brake is the so-called hydraulic brake, which is a mechanical part that stops or slows down the moving parts in the machine. In order to reduce the braking torque and structural size, hydraulic brakes are usually installed on the high-speed shaft of the equipment, but large equipment with high safety requirements (such as mine hoists, elevators, etc.) are installed on the low-speed shaft close to the working part of the equipment. On the shaft, some brakes have been standardized and serialized, and are manufactured by professional factories for selection. The brake pads used in the existing hydraulic brakes are mostly made of asbestos fleece friction materials, which wear quickly during use and have poor heat dissipation performance, and the replacement cycle is short. In view of the above defects, it is necessary to ...
