Abstract
A kind of tapered sleeve shaft coupling only tightens with torque spanner or unclamps round nut when dismounting, whole lighter, and shaft coupling alignment；Because connecting by frictional force, also have the function of protecting prime mover when overload.
Description
Technical field:
The present invention relates to a kind of shaft joints, are a kind of parts for two axis connections, belong to machinery industry.
Background technique:
Present expansion set shaft joint is the axial distance for shortening inner ring and outer rings by tightening multiple clamping screws, makes inner ring and axis
Between, enclasping force is generated between outer ring and wheel hub, realize the connection of axis and wheel hub.The intensity of expansion set shaft joint is high, and super
When load, frictional force fail safe equipment is not damaged；But the multipair bolt for needing diagonally to tighten or unscrew one by one when dismounting, than
It is cumbersome, and expansion set shaft joint is integrally heavier.Roller chain coupling is suitable for middle load-carrying and carries occasion, but its alignment is poor.
Summary of the invention:
The purpose of the present invention: proposing a kind of tapered sleeve shaft joint, is only tightened with torque spanner to solve the above problems, when dismounting or pine
Round nut is opened, it is whole lighter, and also shaft coupling alignment might as well；Because connecting by frictional force, also there is overload
When protect the function of prime mover.
Driving shaft and driven shaft are packed into after shaft coupling, tighten the round nut in external member, the inner cone of external member with torque spanner
Face pressure compels cone part, and cone part is by the pressure for being directed toward big end from small end, and then internal diameter is gradually reduced to firmly grasp driving shaft and driven shaft,
In round thread rundown process, round nut not yet contacts stop washer when torque spanner reaches the moment values of setting, round nut and
Still have about one millimeter of gap between stop washer (should not yet grab designed for preventing round nut from having forced tight stop washer but boring part
Mandrel), the outer stop ear of stop washer is beaten in the notch of indentation round nut prevents external member from rotating backward.
Stop ear is identical with the direction of outer stop ear in existing stop washer, and needs to output one on external thread piece
Elongated slot accommodates interior stop ear, and the fluting on axis can weaken the intensity of external thread piece；And the inside and outside of the stop washer of new model stops
The direction of both dynamic ears is opposite, in the slot of interior stop ear insertion external thread piece side, so external thread piece does not have to along axially grooved,
Such external thread piece intensity will not be weakened, and increase the quantity of outer stop ear, make not having to turn over too greatly during external member locking
Angle can make its outer wrench position and the outer stop ear of stop washer match, and be embedded in after outer stop ear is then suppressed deformation
In outer wrench position.
The alignment of tapered sleeve shaft coupling is good, easy to loading and unloading；When overload, resistance be greater than cone part and between centers frictional force, axis and
Shaft coupling is opposite to be slided, and prime mover is protected.
The diameter dimension of driving shaft and driven axle can be identical or different.In the not of uniform size of driving shaft and driven shaft
The occasion of cause can make external thread piece, cone part, external member that both ends match with two axis respectively to measure.
Tapered sleeve shaft coupling can be made series of products, and the diameter corresponding to axis is every to increase one millimeter of connection that a model is arranged
Axis device.
The steering of thread rotary orientation and axis on shaft coupling matches, so that screw thread pair has and tightens becoming of not loosening at work
Gesture；The axis that right-hand thread cooperation rotates (in terms of from driving shaft toward the direction of driven shaft) clockwise, Left-hand threads cooperation is counterclockwise (from
The direction of driving shaft toward driven shaft is seen) rotation axis.

Specific embodiment:
The embodiment of the present invention is described further with reference to the accompanying drawing.
Production external thread piece 1: round steel is clamped in lathe and is got on the bus external threads 13 and inner cylinder 14, is then clamped on milling machine
Mill out die nut position 11 and side locking groove 12.
Production cone part 2: round steel blank clamping appropriate is got on the bus out male cone (strobilus masculinus) 21 and inner hole 23 in lathe, then in milling machine
On mill out longitudinal seam 22, heat treatment makes to bore the whole diameter with certain toughness inner hole 23 under external member pressure of part 2 and can reduce.
Production external member 3: round steel blank clamping appropriate is got on the bus out round nut 31 in lathe, round nut includes internal screw thread 31
With tapered sleeve 32, the inner conical surface 321 of tapered sleeve 32 is thermally treated to become more wear resistant, then mills out outer spanner position 312；The internal screw thread 31 of design
Length be greater than external thread piece 1 external screw thread 13 length, can ensure that driving shaft 5 and driven shaft 6 are locked in this way.
Production stop washer 4: going out the base shape of stop washer 4 with punching machine combination mold, then in stop ear 42 it is inside or
90 ° of bendings are done outward, outer stop ear 41 does 25 ° of bendings round about.
Operator is first successively respectively fitted over external member 3, cone part 2 on driven shaft 6 and driving shaft 5；External thread piece 1 is first covered
Thread complete set 3 and external thread piece 1 are tentatively tightened on driven shaft 6 again；Driving shaft 5 is put into external thread piece 1, in external thread piece 1
For the upper dial gauge that sets up to detect the bounce of driving shaft 5, the stabilizer blade parallels for then adjusting prime mover makes driving shaft 5 and driven shaft 6
The two is coaxial；It is multiple to twist so that the locking torque of external member 3 and external thread piece 1 reaches design requirement, then by stop washer 4 it is outer only
Dynamic ear 41 is suppressed in the outer spanner position 312 of deformation insertion external member 3.
The above are the preferred embodiment of the present invention, are not intended to restrict the invention, for those skilled in the art,
The invention may be variously modified and varied；All within the spirits and principles of the present invention, any modification for being made, equivalent replacement
Deng should be included within scope of the presently claimed invention.
