Abstract
The invention relates to a screw rolling machine eccentric bushing, comprising a front eccentric bushing, a rear eccentric bushing, a shifting form, and a mandrel. The front eccentric bushing is provided with a front eccentric axle hole. The axis of the front eccentric axle hole and the excircle axis of the front eccentric bushing are in an eccentric shape. The rear eccentric bushing is provided with a rear eccentric axle hole. The axis of the rear eccentric axle hole and the excircle axis of the rear eccentric bushing are in an eccentric shape. The mandrel passes through the front eccentric axle hole and the rear eccentric axle hole. A front holder holding dense balls is arranged between the mandrel and the inner wall of the front eccentric axle hole. A rear holder holding dense balls is arranged between the mandrel and the inner wall of the rear eccentric axle hole. The mandrel and the front eccentric bushing are fixed with a front screw through a front gasket. The mandrel and the rear eccentric bushing are fixed with a rear screw through a rear gasket. The eccentric bushing can ensure unification of eccentricity of the front eccentric bushing and the rear eccentric bushing under unified processing standard of the front eccentric axle hole, the rear eccentric axle hole, the excircle of the front eccentric bushing, and the excircle of the rear eccentric bushing.

Background technology
Screw-rolling machine eccentric bushing is assembly, comprising pre-eccentric cover, rear eccentric bushing, shift fork three part forms, connect by alignment pin and soket head cap screw, there is 26mm offset in brearing bore and the cylindrical of pre-eccentric cover and rear eccentric bushing, because of the restriction of gear box structure, can only assemble in gear-box assembling, parts processing is adopted in prior art, combine in assembling, this just causes the accuracy of manufacture of part to have greater loss to during assembling, main cause is that pre-eccentric overlaps the dowel hole and brearing bore processed with rear eccentric bushing, the benchmark of cylindrical is difficult to reach coincidence, and it is very harsh to the alignment requirements of processing.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, and provide a kind of screw-rolling machine eccentric bushing, machining accuracy is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of screw-rolling machine eccentric bushing, there is pre-eccentric cover, rear eccentric bushing, shift fork, axle, described pre-eccentric cover, rear eccentric bushing is connected by shift fork, described pre-eccentric cover has pre-eccentric axis hole, the cylindrical axis that the axis of described pre-eccentric axis hole and pre-eccentric overlap is eccentric shape, described rear eccentric tackling has rear eccentric pivot hole, the axis of described rear eccentric pivot hole and the cylindrical axis of rear eccentric bushing are eccentric shape, described axle is through pre-eccentric axis hole and rear eccentric pivot hole, the front retainer that close pearl is housed is set between the inwall of described axle and pre-eccentric axis hole, the rear retainer that close pearl is housed is set between the inwall of described axle and rear eccentric pivot hole, described axle and pre-eccentric cover are fixed by front packing ring and front nut, described axle and rear eccentric bushing are fixed by rear packing ring and back nut.
Further, described pre-eccentric cover has the front oil groove path leading to front retainer, and described rear eccentric tackling has the rear oil groove path leading to rear retainer.
Further, described pre-eccentric cover has the prelocalization pin-and-hole needed for being connected with shift fork, described shift fork is fixedly connected with by prelocalization pin with pre-eccentric cover, and described rear eccentric tackling has the rear dowel hole needed for being connected with shift fork, and described shift fork is fixedly connected with by rear alignment pin with rear eccentric bushing.
The invention has the beneficial effects as follows: the present invention can ensure that the cylindrical of the cylindrical that pre-eccentric axis hole, rear eccentric pivot hole, pre-eccentric overlap, rear eccentric bushing is under unified machining benchmark, meet the unification of offset of pre-eccentric cover, rear eccentric bushing.And meet further pre-eccentric cover to be connected with shift fork needed for prelocalization pin-and-hole, rear eccentric bushing be connected with shift fork needed for rear dowel hole, the cylindrical that pre-eccentric overlaps, rear eccentric bushing cylindrical under unified machining benchmark.
