Description

A kind of system and its production technology for producing tapered sleeve
Technical field
The present invention relates to the technical field of tapered sleeve production, particularly a kind of system and its production technology for producing tapered sleeve.
Background technology
Tapered sleeve is the novel mechanical driving coupling part that a kind of American-European countries generally uses, and has standardization level high, smart Spend the features such as high, compact-sized, easy installation and removal.It is outside one's consideration the conical surface and belt pulley, sprocket wheel and other driving member inner conical surfaces by 8 Connection is compressed, greatly improves the centering precision of various driving members.Tapered sleeve size designs for series standard.Versatility interchangeability is very It is good, various occasion are applicable when driving member passes through long time running, and endoporus and keyway may be damaged, if using cone Set is used as driving member, when this thing happens, need to only change same specification tapered sleeve can and recover to use.Thus greatly improve biography Moving part service life, maintenance cost is reduced, saves the time.
As shown in figure 1, being the structural representation of tapered sleeve, tapered sleeve is all half of with the hole at the belt pulley place of being engaged, and Two and half shape unthreaded holes 50 on tapered sleeve and two and half shape screwed holes on belt wheel have separately constituted a complete hole, on tapered sleeve One and half shape screwed holes 51 constitute a complete hole with one and half shape unthreaded holes on belt pulley again, and half shape screwed hole 51 is located at Between two and half shape unthreaded holes 50.In assembling, by two screwed holes of two screw precessions in belt pulley and the institute of half shape unthreaded hole 50 In the complete bore of formation, with constantly being tightened in the screwed hole of screw over pulleys carried, threaded function pushes screw to belt pulley The small end of upper taper hole, and two unthreaded holes on taper sheath not wear by processing completely, so, when the head of screw props up unthreaded hole During bottom, tapered sleeve is just transmitted the force to, tapered sleeve is with respect to small end motion of the belt pulley to belt pulley taper hole, at this moment because cone The reason for spending, tapered sleeve just constantly packs tightly axle, and axle reacts on tapered sleeve, remakes for belt pulley.So belt pulley, tapered sleeve And axle just closely fits together.
To realize the processing of two and half shape unthreaded holes 50 and one and half shape screwed holes 51 on tapered sleeve, generally use either simplex sequence is carried out Processing, i.e., three holes are drilled out on the large end face of blank first with drilling machine, recycle tapping machine to carry out tapping to one of hole, Subsequently enter face milling processing, finally carry out bore hole, but tool locating again is required for per procedure, it is difficult to ensure that hole with Positional precision between hole, ultimately result in processing after tapered sleeve can not match on belt pulley, additionally, there may be it is cumbersome, very Difficulty realizes continuous production, reduces production yields, can not meet the needs of market.
Keyway 53 is offered on the centre bore of this external conical sleeve, groove 52 is further opened with tapered sleeve outer wall, passes through radial compression Tapered sleeve makes it somewhat shrink, and tapered sleeve can just correctly entered in belt pulley, but existing mode of grooving is used using artificial Saw blade is cut, and is often sawed a groove and is required for repositioning, greatly increases labor strength, and reduce tapered sleeve Production efficiency.
