Description

Snake-shaped spring coupling

Technical Field

The utility model relates to a shaft coupling field specifically indicates a serpentine spring shaft coupling.

Background

The coupling is also called coupling. Mechanical parts for firmly coupling the driving shaft and the driven shaft in different mechanisms to rotate together and transmitting motion and torque. Usually, the two halves are combined and fastened to the two shaft ends by a key or a tight fit, and then the two halves are connected in a certain way. The coupling can compensate the offset between the two shafts caused by inaccurate manufacture and installation, deformation or thermal expansion in work and the like, including axial offset, radial offset, angular offset or comprehensive offset; and shock mitigation and absorption. The existing coupler is installed and disassembled only by stopping and moving the main machine away when being installed and disassembled, and the main machine can be started to operate after being moved to a corresponding position again after the installation is finished, so that the maintenance is very inconvenient, the machine is long in downtime, and the production cost of a factory is correspondingly increased.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome above difficulty, when providing an installation and dismantlement shaft coupling, a serpentine spring shaft coupling that need not move the host computer and can go on.

In order to solve the technical problem, the utility model provides a technical scheme does: a serpentine spring coupling comprises a housing and a serpentine spring, wherein openings are arranged at two axial ends of the housing, a containing cavity is arranged in the housing, a first bearing guide piece and a second bearing guide piece are arranged in the containing cavity, a connecting part of the first bearing guide piece and the second bearing guide piece is provided with a clamping groove and a buckle which are matched with each other, the inner side peripheral surfaces of the axial centers of the first bearing guide piece and the second bearing guide piece are provided with a groove, the outer side peripheral surfaces of the axial centers of the first bearing guide piece and the second bearing guide piece are respectively and correspondingly provided with a first fluted disc and a second fluted disc, the end surfaces of the first fluted disc and the second fluted disc are attached, the outer side peripheral surfaces of the first fluted disc and the second fluted disc are provided with tooth grooves, the serpentine spring is arranged in the tooth grooves, gaps are reserved between two ends of the serpentine spring and the inner wall of the housing, a sealing retainer ring is arranged in the gaps, and the sealing retainer, the opening parts at the upper two ends of the housing are provided with sealing grooves, and sealing rings are arranged in the sealing grooves.

In a further development, the first toothed disc is fixedly connected to the first bearing guide and the second toothed disc is fixedly connected to the second bearing guide.

As a modification, the housings are connected by bolts.

Compared with the prior art, the utility model the advantage lie in: draw-in groove and buckle slip block each other on first bearing piece and the second bearing piece make the installation with need not remove the host computer when dismantling and can go on, serpentine spring can absorb when the host computer moves and assault and vibration, makes the host computer move more steadily, and sealing ring can reduce serpentine spring to the impact of housing, and the sealing washer can reduce the dust and get into between first bearing piece of gap protection, second bearing piece, the serpentine spring, makes the machine move more steadily.
