Abstract
Provided is a novel overload protection structure of a coupler. A driving friction disc is installed at one end of a driving shaft through a driving shaft key, a pressure spring is installed between a step and the driving friction disc, a driven friction disc is fixedly connected with a driven shaft through a driven shaft key, and a convex-concave matching relation is formed between concentric circular V-shaped grooves on the driving friction disc and the driven friction disc. Power of the driving shaft is transmitted through the friction force generated under the compressing conditions of the driving friction disc and the driven friction disc, and the friction force depends on pressure of the pressure spring. Therefore, the novel overload protection structure of the coupler can not only protect a prime motor from being impacted, but also protect a transmission system when overload occurs.
Description
Technical field
The present invention relates to a kind of structure of overload protection coupling, particularly a kind of structure of novel overload protection coupling belongs to the mechanical parts technical field.
Background technique
Coupling is a kind of parts that connect dynamic power machine and input shaft in the mechanical transmission, plays that in mechanical transmission prime mover is shielded; At present, in the product of coupling, though the structure of coupling be not quite similar,, all coupling just have protective action to the impact of prime mover, can't play a protective role for the overload of transmission system.
Summary of the invention
The objective of the invention is to: a kind of structure of novel overload protection coupling is provided, and the structure of this overload protection coupling is except having impact to prime mover plays a protective role, and simultaneously, also can play a protective role for the overload of transmission system.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of structure of novel overload protection coupling; It is an end that is installed in driving shaft by the active friction disk through the active axle key; Pressure spring is installed between step and the active friction disk; Driven friction disk is fixedly connected through passive axle key with driven axle, initiatively formation convex-concave matching relationship between the concentric round V-type groove on friction disk and the driven friction disk.
Beneficial effect: the structure of a kind of novel overload protection coupling of the present invention; The power of driving shaft is realized transmission through active friction disk and driven friction disk in the frictional force that compresses under the situation, and the size of frictional force is by the pressure decision of pressure spring, so; The structure of a kind of novel overload protection coupling of the present invention; Except having impact to prime mover plays a protective role, simultaneously, also can play a protective role for the overload of transmission system.
