Description

Ratchet coupling with special transmission

Technical Field

The utility model belongs to the field of steelmaking continuous casting, and relates to a ratchet coupling with special transmission.

Background

The coupling is a device for connecting two shafts or a shaft and a rotating part, rotating together in the process of transmitting motion and power and not separating under normal conditions. Sometimes it is used as a safety device to prevent the coupled machine parts from bearing excessive load, and it plays the role of overload protection.

Couplings can be divided into two broad categories, rigid couplings and flexible couplings. Rigid coupling: the coupler does not have the buffer property and the capability of compensating the relative displacement of the two axes, and the two axes are required to be strictly centered. Flexible coupling: the flexible coupling can be divided into an inelastic element flexible coupling and an elastic element flexible coupling, the former type only has the capability of compensating relative displacement of two axes but cannot buffer and damp vibration, and the sliding block coupling, the tooth type coupling, the universal coupling, the chain coupling and the like are common.

The billet conveying roller ways of steel plants and steel rolling plants are damaged in a short time due to large difference of rotating speed.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides a special transmission ratchet coupling, which organically combines a ratchet structure and a transmission coupling, and solves the problem of equipment damage caused by impact load when the same billet is lapped on roller tables with different rotation speeds.

Optionally, the star half coupler is further provided with a bearing, a bearing outer sleeve arranged outside the bearing and an end cover fixed on the bearing outer sleeve through a fastener and used for fixing the bearing;

optionally, the bearing outer sleeve is fixedly connected with the ratchet gear ring through a hinged bolt and a hinged nut.

Optionally, a cam positioning plate is fixedly mounted between the star half coupler and the bearing outer sleeve through a third bolt.

Optionally, the driving end half-coupling is fixedly connected with the star-shaped half-coupling through a second bolt.
