Abstract
The utility model relates to a machine part, in particular to a joint slack, comprising an inner shaft sleeve, a slot sleeve and a key box located on the inner shaft sleeve, wherein the inner shaft sleeve is connected with the slot sleeve through a flat end on the inner shaft sleeve, the shape of the flat end is a cylinder which is concentric with the inner shaft sleeve, whose height is smaller than that of the inner shaft sleeve, whose diameter is bigger than that of the inner shaft sleeve, and which is cutting along two ends of a same axial cord, wherein the inner shaft sleeve comprises an inner shaft sleeve I and an inner shaft sleeve II, external flat ends of the inner shaft sleeve I and the inner shaft sleeve II can be perpendicular to each other in installing, and can be mutually parallel, the slot sleeve comprises a slot sleeve I and a slot sleeve II, which are respectively matched with the inner shaft sleeve I and the inner shaft sleeve II, the slot sleeve I is connected with the slot sleeve II through a bolt, the slot sleeve can be made into an integrated structure, and two ends of the slot sleeve are provided with retainers matched with the slot sleeve. The joint slack has simple structure, low requirement in installing accuracy, longer service lift and low manufacture cost, and is easy to realize rapid change.
Description
Technical field:
The utility model relates to a kind of mechanical parts, relate in particular to a kind of coupling.
Background technique:
Coupling is the mechanical parts on a kind of basis of mechanical field, and general power engine mostly links by means of coupling and working machine, so the quality of coupling is also very big to the performance impact of entire machine.And in actual applications,,, thereby cause being unfavorable for the quick replacing of coupling because employed coupling boundary dimension is bigger than normal, complex structure or installation precision require than higher especially in the occasion of some low-speed heave-loads; In addition, in the abominable occasion of environment, the life-span of coupling is shorter, has improved cost of production accordingly.Existing in prior technology deficiency that Here it is.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, provides a kind of simple in structure, long service life, installation precision is less demanding and be easy to quick-replaceable coupling.
This programme is realized by following technical measures: this coupling, comprise internal axle sleeve, flat borehole jack and be positioned at keyway on the internal axle sleeve, described internal axle sleeve is connected by the homalocephalus on the internal axle sleeve with flat borehole jack, homalocephalus be shaped as with internal axle sleeve concentric and height less than internal axle sleeve height, diameter greater than internal axle sleeve diameter, cylindrical along the cutting of same axis two ends, the circular arc of homalocephalus can reduce position and the augular offset between the diaxon that the coupling two ends connect, and the planar section of the side cut of homalocephalus can transmit bigger torque under with the situation of speed ratio.
Above-mentioned internal axle sleeve comprises internal axle sleeve I and internal axle sleeve II, homalocephalus on internal axle sleeve I and the internal axle sleeve II can be mounted to orthogonal, also can be mounted to parallel to each otherly, when coaxality is less demanding, can make the homalocephalus on internal axle sleeve I and the internal axle sleeve II orthogonal during installation; When coaxality is had relatively high expectations, can make the homalocephalus on internal axle sleeve I and the internal axle sleeve II parallel to each other during installation.
Above-mentioned flat borehole jack comprises flat borehole jack I and flat borehole jack II, cooperates with internal axle sleeve I and internal axle sleeve II respectively, and flat borehole jack I is connected by bolt with flat borehole jack II; Also flat borehole jack can be made of one structure, can select different structural type according to different operation needs.
There is the back-up ring that is mated at above-mentioned flat borehole jack two ends, and back-up ring both can prevent flat borehole jack axial float effectively, can guarantee again to have enough lubricant oil in the flat borehole jack.
The beneficial effect of this programme can learn that this coupler structure is simple according to the narration to such scheme, is easy to realize quick replacing, and it can self-aligning, and installation precision requires lower, and working life is longer, has reduced cost of production.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
