Abstract
The invention discloses a shaft coupler with a safety protection function. The shaft coupler with the safety protection function comprises a first half-shaft coupler and a second half-shaft coupler, wherein the second half-shaft coupler is embedded into the first half-shaft coupler; the first half-shaft coupler and the second half-shaft coupler are connected through a safety pin shaft. When a driven part is deadly clamped, a torque delivered between the first half-shaft coupler and the second half-shaft coupler increases rapidly; when the torque value increases to a certain value, the safety pin shaft is sheared off, the connection between the first half-shaft coupler and the second half-shaft coupler is cut off, and the safety protection function is accordingly played.
Description
Technical field
The present invention relates to a kind of coupling for transmitting torque, particularly a kind of coupling with function of safety protection.
Background technique
Coupling is parts conventional in mechanical transmission, is mainly used to the intermediate transmission mechanism of joining shaft and axle or joining shaft and other revolution part, to transmit motion and torque.In the transmission system of current most of equipment, driving link and driven member are all directly be connected by gear, spline engagement or other modes.In transmission system, use these above Placements, when driven member because of fault stuck time, be connected because driven member cannot depart from driving link, and cause driving link and driven member simultaneously impaired.In the equipment run up, this type of fault may cause that equipment is badly damaged even to be scrapped.
Summary of the invention
Goal of the invention: in order to solve the problems of the technologies described above, the invention provides a kind of coupling of the band function of safety protection that driving link and driven member can depart from when driven member is stuck.
Technological scheme: a kind of coupling with function of safety protection, comprises the first half-coupling and the second half-coupling, and described second half-coupling is inlaid in the first half-coupling, by safe pinned connection between described first half-coupling and the second half-coupling.When driven member is stuck, the moment of torsion of the transmission between the first half-coupling and the second half-coupling is caused to increase sharply, when torque value increases to certain value, safe bearing pin is cut off, and the connection between the first half-coupling and the second half-coupling disconnects, thus plays the function of safety protection.
Preference, described first half-coupling one end is provided with the first flange edge, described second half-coupling is provided with the second flange edge, described first flange edge and the second flange edge are adjacent to mutually, and are circumferentially provided with the through hole for installing safe bearing pin that at least three groups run through the first flange edge and the second flange edge.
Preference, second half-coupling is embedded in the first half-coupling completely, described first half-coupling one end is provided with the sleeve for holding the second half-coupling, the first bearing pin mounting hole and the second bearing pin mounting hole for installing safe bearing pin that described sleeve is all identical with the second half-coupling peripheral wall being respectively equipped with quantity, position and size.
Beneficial effect: the present invention's can be cut off by safe bearing pin, thus when realizing driven member fault, whole coupling disconnects, thus serve the function of protection driving link.
