Environment-friendly noise-reduction energy-saving device for electromagnetic brake

Abstract

The invention relates to an environment-friendly noise-reduction energy-saving device for an electromagnetic brake. The environment-friendly noise-reduction energy-saving device for the electromagnetic brake comprises a brake disc base body, a brake disc, a wear-resistant noise-reduction spline sleeve and a hollow spline shaft. The brake disc and the brake disc base body are vulcanized or bonded together; the brake disc base body is in a disc shape with a boss, and a spline hole is formed in the center of the brake disc base body; the wear-resistant noise-reduction spline sleeve is connected to the interior of the spline hole in a sleeving mode; the wear-resistant noise-reduction spline sleeve is in a hollow cylindrical shape, and spline grooves are formed in the cylindrical inner surface and the cylindrical outer surface of the wear-resistant noise-reduction spline sleeve; an outer spline groove of the wear-resistant noise-reduction spline sleeve is matched with the spline hole; splines are arranged on the outer circle of the hollow spline shaft; and a spline of the hollow spline shaft is matched with an inner edge spline groove of the wear-resistant noise-reduction spline sleeve. The brake disc base body is made of aluminum alloy, and the thickness of the wear-resistant noise-reduction spline sleeve is 0.15-0.8 mm. and the wear-resistant noise-reduction spline sleeve is made of PA66 and glass fibers. The environment-friendly noise-reduction energy-saving device for the electromagnetic brake has the beneficial effects that through the wear-resistant noise-reduction spline sleeve, the impact force of the brake disc is effectively reduced, noise is reduced, and the working environment is more comfortable.

Description

technical field [0001] The invention relates to the technical field of brake discs, in particular to an environment-friendly, noise-reducing and energy-saving device for electromagnetic brakes. Background technique [0002] The technology of the brake disc is relatively mature at present, and it is also widely used in equipment such as automobiles, trains, motors, and automatic control devices; while the brake disc generally needs to be moved during use, and the brake disc is connected to the device that drives the brake disc Usually, it is connected by splines. The brake disc is provided with a spline groove, and the device for driving the brake disc is provided with a spline shaft. Due to the need for frequent braking, the spline shaft needs to slide repeatedly in the spline groove. The fit gap is too large, resulting in noise. At the same time, when the gap becomes larger, the impact force during braking will also be increased, and the wear of each component will be accel...

[0002] The technology of the brake disc is relatively mature at present, and it is also widely used in equipment such as automobiles, trains, motors, and automatic control devices; while the brake disc generally needs to be moved during use, and the brake disc is connected to the device that drives the brake disc Usually, it is connected by splines. The brake disc is provided with a spline groove, and the device for driving the brake disc is provided with a spline shaft. Due to the need for frequent braking, the spline shaft needs to slide repeatedly in the spline groove. The fit gap is too large, resulting in noise. At the same time, when the gap becomes larger, the impact force during braking will also be increased, and the wear of each component will be accelerated, which urgently needs to be solved;

[0003] In the prior art, the spline shaft is directly connected to the brake disc base. In order to reduce friction and resistance, it is necessary to add butter to the spline; when the brake disc is used, the butter will inevitably flow to the brake disc The braking surface of the brake disc; the brake disc is generally made of resin and wear-resistant materials; after the butter flows on the brake disc, it will affect the braking performance of the brake disc; in the rainy season in the south or in the winter in the north, construction sites Generally, it will stop working. For equipment using brake discs, such as elevators and elevators, due to long-term non-use, the butter will harden between the brake disc base and the spline shaft, and the spline shaft and the system will be caused when the machine is turned on again. The base of the moving disc is stuck, causing the brake to not brake. The above problems need to be solved
