Abstract
The utility model discloses the safety coupling of a brake wheel, which comprises a brake wheel arranged on the high speed shaft of a speed reducer. The driving surface of the brake wheel is in a cylindrical shape. A ring gear is fixedly connected with the brake wheel through a bolt. An outer gear shaft sleeve is arranged inside the ring gear. An outer tooth blade A is arranged between the ring gear and the outer gear shaft sleeve. A friction plate mechanism is arranged on one side of the outer tooth blade A. The friction plate mechanism comprises two outer tooth blades B, two friction plates and an inner tooth blade. The two friction plates and the inner tooth blade are sandwiched between the two outer tooth blades B. The friction plates are arranged on the two sides of the inner tooth blade. The end of the friction plate assembly, which is away from the outer tooth blade A, is successively provided with an adjusting pad, an end cap, and a bolt group fixedly arranged on the adjusting pad. The bolt group comprises a nut and a bolt. The end cap is provided with a spring. According to the utility model, a belt brake wheel type brake is adopted instead of a closed-type multi-friction-plate brake, and the safety coupling of a brake wheel can be used for braking.
Description
Technical field
The utility model relates to the coupling technical field, especially relates to a kind of Brake drum safety coupling.
Background technique
Many friction disc brakes of enclosed device adopts the secondary transmitting torque of steel-copper powders may asbestos friction, can make weight keep static or under the state of emergency, carries out retarding braking, but can not use as brake device.Many friction disc brakes of enclosed device structure is compact; Regulate simple and reliable; It is commonly used in planet-gear speed reducer such as revolution, elevator and the engineering machinery, is the desirable brake unit of swirl gear and hoisting mechanism, for the engineering occasion of need with big braking moment and work under bad environment; The utility model changes many friction disc brakes of enclosed device into band brake wheel type, to satisfy the needs of engineering.
The model utility content
The purpose of the utility model is exactly in order to address the above problem, and a kind of Brake drum safety coupling is provided.
To achieve these goals, the utility model adopts following technological scheme:
A kind of Brake drum safety coupling is characterized in that, comprises
One is installed in the Brake drum (1) on the speed reducer high speed shaft, and its drive face is cylindrical;
One passes through the ring gear (2) that bolt is fixedly connected with Brake drum;
One is located at the external tooth axle sleeve (3) in the ring gear, wherein,
Be provided with an outer gear piece A (4) between said ring gear (2) and external tooth axle sleeve (3), be located at the friction plate mechanism of outer gear piece A one side; This friction plate mechanism comprises two outer gear piece B (5) and is held on two friction plates (6) and the inner blade (7) between the outer gear piece B; Said friction plate (6) is distributed in the both sides of inner blade (7); The friction plate group is provided with spacer (8), end cap (9) successively and is fixed in the bolt group on the spacer away from outer gear piece A end; This bolt group comprises nut (11) and bolt (12), and said end cap is equiped with spring (10).
The beneficial effect of the utility model is to change many friction disc brakes of enclosed device into band brake wheel type, can be used as skidding and uses.
