Description

A kind of gapless spline coupling
Technical field
The utility model relates to a kind of gapless splined shaft coupling, belongs to mechanical transmissioning technology field.
Technical background
Splined has following feature in intensity, technique and use: because directly and equably make more tooth and groove on axle with on hub bore, therefore connect stressed comparatively even; Because groove is more shallow, tooth root place stress is concentrated less, and the strength reduction of axle and hub is less; The number of teeth is more, and total area of contact is larger, thereby can bear larger load; The centering of parts on shaft and axle is good, and this is very important to high speed and precision machinery.The applicable centering precision requirement of splined is high, transmitting torque is large or the connection of frequent slippage.
Coupling and axle adopt splined more, and splined is owing to adopting multiple tooth cooperation, and error is larger, in order to install, convenient disassembly, must be designed to Spielpassung.In some large impacts or the occasion frequently that commutates, gappedly just easily there are the wearing and tearing of the flank of tooth.And while using gapless to transmit, splined adds and has processing, the large shortcoming of installation and removal difficulty.For these shortcomings, also there is people to improve spline coupling, the installation and removal of spline coupling have been facilitated many, but or can not eliminate gap completely, eliminate the wearing and tearing to the flank of tooth.
Summary of the invention
The problem existing for solving above-mentioned prior art, the utility model provides a kind of gapless spline coupling, and these coupling installation and removal are convenient, and after installation, coupling compresses splined shaft, thoroughly eliminates spline gap, thoroughly eliminates the wearing and tearing to the spline flank of tooth.
Realize the technological scheme that the utility model object is taked:
A kind of gapless spline coupling, at least comprise spline housing and hexagon socket head cap screw, hexagon socket head cap screw is arranged in spline housing, spline housing has the groove from axial subdivision by axle sleeve on radially, the width of groove is 1~3 millimeter, the groove degree of depth is diametrically 0.65~0.75 times of spline housing external diameter, one side of spline housing inner splined hole is evenly provided with at least two for connecting the screw hole of spline housing, each screw hole is all vertically through groove, in screw hole, be separately installed with hexagon socket head cap screw, on spline housing spline housing, along spline housing, be axially arranged with two lightening holes, two lightening holes are all positioned at the side that splined hole is relative with screw hole.
Described screw hole is two, and two screw holes are all positioned at the centre of sleeve lining and outer wall.
Described hexagon socket head cap screw strength grade is 12.9.
As shown from the above technical solution: the length diametrically of the groove on spline housing is 0.65~0.75 times of spline housing external diameter, and be groove in the axial direction, on spline housing, fluting makes the installation and removal of splined shaft very convenient, and because groove is very little in the length of axle sleeve hole opposite side, after hexagon socket head cap screw is tightened, gap can be do not produced, tooth surface abrasion can be do not caused.Due to the width of groove very little, only have 1~3 millimeter, and the grade of hexagon socket head cap screw is 12.9, be high strength screw, after hexagon socket head cap screw is tightened, axle sleeve can be easy to compress splined shaft, groove can disappear, thereby is easy to spline gap to eliminate.High-intensity hexagon socket head cap screw is also very firm, is not easy to produce distortion, and Safety performance is high and increase considerably working life of this coupling.If while needing dismounting couplers because of maintenance, unclamp hexagon socket head cap screw and get final product dismounting couplers.The more important thing is, this coupling is provided with lightening hole, makes the weight balancing of axle sleeve hole both sides axle sleeve, and the weight of whole axle sleeve, in state of equilibrium, makes the vibration of coupling little, is more conducive to coupling and runs up, and is conducive to improve the working efficiency of coupling.
The beneficial effects of the utility model and advantage are:
These coupling installation and removal are convenient, fast, use this coupling can thoroughly eliminate spline gap, thoroughly eliminate the wearing and tearing to the spline flank of tooth in the splined of splined shaft and spline housing, and the long service life of this coupling, Safety performance is high and working efficiency is high.
Accompanying drawing explanation
The structural representation of the gapless spline coupling that Fig. 1 provides for the utility model and splined shaft assembling.
Fig. 2 is the partial sectional view of Fig. 1.
1-spline housing, 2-screw hole, 3-hexagon socket head cap screw, 4-groove, 5-lightening hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
As depicted in figs. 1 and 2, this coupling at least comprises spline housing 1 and hexagon socket head cap screw 3 to the structure of the gapless spline coupling that the utility model provides, and spline housing has the groove 4 from axial subdivision by axle sleeve on radially, and the width of groove is 1~3 millimeter.The width of groove is smaller, is more conducive to eliminate gap after tightening the screw.Groove 4 degree of depth is diametrically 0.65~0.75 times of spline housing 1 external diameter, and such design makes groove very little in the length of axle sleeve hole opposite side, after two hexagon socket head cap screws are tightened, can not produce gap, can not cause tooth surface abrasion.One side of spline housing 1 inner splined hole is evenly provided with at least two for connecting the screw hole 2 of spline housing.Screw hole number arranges according to sleeve length, and the length of axle sleeve is longer, and the number of screw hole is more, and screw hole is evenly to arrange, and the coupling mechanism force after screw tightening is larger, is more conducive to eliminate gap.In the present embodiment, the number of screw hole is two, and two screw holes are all positioned at the centre of sleeve lining and outer wall.Each screw hole 2, all vertically through groove, is separately installed with hexagon socket head cap screw in screw hole.Hexagon socket head cap screw strength grade is 12.9.Hexagon socket head cap screw is high strength screw, has improved the safety coefficient and the working life that has extended coupling of coupling.On spline housing spline housing, along spline housing, be axially arranged with 5, two lightening holes of two lightening holes and be all positioned at the side that splined hole is relative with screw hole.The setting of lightening hole is in order to make the overall weight balance of axle sleeve, reduces vibration, improves the working efficiency of axle sleeve.
The using method of the gapless spline coupling that the utility model provides:
Splined shaft is arranged on after spline housing, hexagon socket head cap screw is arranged on respectively in screw hole, by tightening the screw, make spline housing produce inside deformation, thereby splined shaft is compressed, disappear thoroughly except spline gap.
