Abstract
The invention provides a coupler with an overload protection function, which is characterized in that a driving friction disk is arranged at one end of a driving shaft by a driving shaft key so as to ensure that the driving friction disk has degree of freedom (DOF) for sliding along the axial direction and non-rotational DOF; and a pressure spring is arranged between a step A and the driving friction disk, and a driven friction disk and a driven shaft form a fixed connection by a driven shaft key so as to ensure that concentric rounded V-shaped grooves on the driving friction disk and the driven friction disk form a concavo-convex cooperation relationship.
Description
Technical field
The present invention relates to a kind of coupling, refer in particular to coupling, belong to the mechanical parts technical field with overload protection function.
Background technique
To be a kind of parts of connecting dynamic power machine and input shaft in the mechanical transmission play protective action to prime mover in mechanical transmission with coupling; At present, in the product of coupling, though the structure of coupling be not quite similar,, so these coupling just to its protective action of 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 overload protection coupling is provided, this overload protection coupling except having to the surge protection effect of prime mover 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 overload protection coupling; it is an end that the active friction disk is installed in driving shaft by the active axle key; guarantee that initiatively friction disk has the degrees of freedom of sliding vertically; there is not the degrees of freedom of rotating; pressure spring is installed between step A and the active friction disk; driven friction disk and driven axle are formed a fixed connection by passive axle key, guarantee initiatively on the friction disk and driven friction disk formation convex-concave matching relationship between the concentric round V-type groove.
Beneficial effect: a kind of overload protection coupling of the present invention; the power of driving shaft is realized transmission by active friction disk and driven friction disk in the frictional force that compresses under the situation; the size of frictional force is by the pressure decision of pressure spring; so; a kind of overload protection coupling of the present invention; except having to the surge protection effect of prime mover and, simultaneously, also can play a protective role for the overload of transmission system.
