Description
Technical Field
The utility model relates to a speed reducer convenient to manual drive belongs to speed reducer technical field.
Background
In the application process of the speed reducer, if faults occur, the speed reducer needs to be removed, and due to the fact that some applications need to be operated under the condition that the power is not supplied, the output end of the speed reducer drives the reduction gear to rotate reversely, and therefore much inconvenience is brought to maintenance.
In addition, the brake of the input end of the speed reducer can be divided into: standard brake and hand release brake, wherein, the basic operating principle of standard brake: under the action of the elastic force of the spring, the magnetic conduction pressure plate on the brake friction plate pushes the motor in the opposite direction, so that friction force is generated between the brake friction plate and the heat dissipation fan blade, and the braking purpose is further generated. After the magnetic force is generated by the wire feeding coil body, the brake friction plate is forced to move towards the motor direction so as to offset the thrust of the spring and eliminate the friction force between the brake friction plate and the heat dissipation fan blade, thereby generating the brake release effect.
The standard brake has the defect that under the condition that the motor stops, the brake friction plate cannot be separated from the heat dissipation fan blade manually, so that the effects of releasing the brake and adjusting the motor are achieved.
Basic working principle of hand-release brake: the elastic force of the spring in the spring bolt component is used, and the thrust of the armature plate towards the motor direction is used, so that the armature plate, the brake friction plate and the motor back support generate friction force between every two parts, and the braking purpose is further generated. After the magnetic force is generated by the wire feeding coil body, the armature plate is forced to move towards the opposite direction of the motor so as to offset the thrust of the spring in the spring bolt assembly and eliminate the friction force between the armature plate and the brake friction plate, thereby generating the brake release effect.
The hand-released brake has the following disadvantages:
1. the coil body is arranged on the uppermost surface and does not have the fan blade heat dissipation function, so that the temperature of the motor is overhigh when the motor runs for a long time.
2. The 6 groups of nuts in the adjusting bolt kit are used for adjusting the brake clearance, and the assembly is time-consuming.
3. The motor axis is fixed with the hexagonal block through a mounting key and then connected with the brake friction plate through six opposite surfaces of the hexagonal block. When the motor runs, the brake friction plate rotates together with the axis of the motor, but is not fixed up and down, so the brake friction plate can move up and down and rub with the armature plate and the rear support of the motor, thereby abrasion is generated, the service life is influenced, and meanwhile, the friction process can generate sand sound. When the motor stops and starts, strong impact force is generated between the brake friction plate and the hexagonal block instantly, so that the hexagonal hole of the brake friction plate is lost, the clearance between the brake friction plate and the hexagonal block is enlarged, and the braking force is delayed.
