Description
Technical Field
The utility model relates to a shaft coupling technical field, especially a swinging unlubricated air compressor shaft coupling assembly.
Background
The air compressor coupling is generally a device for connecting the rotary power of the motor to the air compressor through a belt and a pulley so as to smoothly start the air compressor. When the air compressor has serious irrecoverable abnormality (or fault) and overload operation exceeding a torque limit is generated, such as stopping the rotation of an air compressor shaft, the power between a belt pulley and the air compressor is immediately and automatically cut off by an air compressor coupling, so that the damage of a belt connecting an engine and the belt pulley and the power loss of the engine are prevented, and the safety of other parts can be ensured.
Chinese patent publication No. CN202500916U discloses a vehicle-mounted dry screw air compressor safety coupling, which includes a motor end flange connected to a motor end and a compressor end flange connected to a compressor end, wherein both the motor end flange and the compressor end flange are provided with locking screws. The design key points are as follows: the air compressor safety coupling is characterized in that one end of a motor end flange is fixedly connected with a first transition flange, one end of a compressor end flange is fixedly connected with a second transition flange, the outside of the first transition flange is connected with the outside of the second transition flange in a positioning mode through a safety transmission pin, the inside of the first transition flange is movably connected with the inside of the second transition flange through a central shaft, the safety coupling can improve the transmission stability between the air compressor and the motor, but the safety coupling is rigidly connected, so that the air compressor is greatly vibrated in the operation process.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, a swing type no-lubrication air compressor shaft coupling assembly has been designed, the double-end flange that flange, one end and air compressor machine that is connected including one end and transmission end are connected, the other end of double-end flange is connected with the center pin, flange's the other end is equipped with elastic coupling, elastic coupling and center pin are connected.
Preferably, the center pin includes pole portion, and locates the disc of pole portion one end, the central axis of pole portion is on the same straight line with the central axis of disc, double-end flange is connected with disc one side, the opposite side and the elastic coupling of disc are connected.
Preferably, a protective cover is arranged on the outer side of the elastic coupling, one side of the protective cover is connected with the connecting flange, and the other side of the protective cover extends to the outer side of the disc.
Preferably, the elastic coupling is a rubber coupling.
The utility model has the advantages that: the oscillating type unlubricated air compressor coupling assembly changes rigid connection between a compressor and a transmission shaft into flexible connection, improves torque, and reduces vibration of the compressor and the whole machine.
