Abstract
The invention discloses a rotor piece processing method, particularly a processing method for an elevator traction machine rotor piece. The method comprises the following processing steps: firstly, drilling holes: drilling holes in the surface of a rotor piece and choosing cutters with different diameters as required; secondly, conducting finish turning: conducting finish turning on the inner surface and the outer surface of the rotor piece and then on the connecting part of the rotor piece, the allowance is 0.025-0.03 mm; thirdly, rolling: adopting a hob cutter to roll the connecting part after finish turning to the required precision; and fifthly, tapping: performing thread tapping on the threaded holes of drilling holes. The hob cutter is a cylindrical hob cutter. As rolling is added based on the original process, the degree of finish of the connecting part is increased by more than 95% after the connecting part is rolled by the hob cutter, and the cylindricity is also increased greatly, so that a bearing can be matched with the rotor piece precisely, the service life of the traction machine can be prolonged, and the transmission efficiency can be improved.
Description
Technical field
The present invention relates to a kind of processing method of rotor element, particularly relate to a kind of processing method of elevator traction machine rotor element.
Background technology
Elevator is the sign of modern society's material progress progress, be that numerous places such as airport, station, harbour, market, office block, high residential building all have application, elevator has effectively been accelerated social rhythm, improved condition of work, improved living standard, elevator kind in the market is also more various, as elevator and escalator etc., and traction machine is the core driver part of elevator, is called as " heart " of elevator.
Traction machine generally comprises support; stator; rotor element; brake etc.; rotor element is installed on the power transmission shaft by key and power transmission shaft rotates together; rotor element is fixed on the support after bearing is installed; so the connecting portion required precision to the rotor element connection bearing is higher; the processing method of existing rotor element is to adopt casting and pouring to become blank earlier; carrying out fine finishining; because causing the installing hole place to be contracted through regular meeting in casting send; make and when the following adopted lathe carries out fine finishining, cause precision to be difficult to reach standard; and this processing method connecting portion difficulty of processing is higher; be difficult to the arrival standard, in use cause the rotor element fracture through regular meeting, the service life of rotor element is shorter.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the processing method of the elevator traction machine rotor element that a kind of connecting portion precision that can make the rotor element connection bearing improves.
A kind of processing method of elevator traction machine rotor element, finish according to following processing step:
One, boring: holed in the rotor element surface, select the cutter of different-diameter as requested;
Two, finish turning: earlier finish turning is carried out on the inside and outside surface of rotor element, again the rotor element connecting portion is carried out finish turning, surplus is 0.025mm-0.03 mm;
Three, roll extrusion: adopt hobboing cutter to be rolled into desired precision the connecting portion behind the finish turning;
Four, tapping: the screwed hole to boring carries out tapping.
Hobboing cutter in the described step 3 adopts cylindrical hobboing cutter.
Beneficial effect compared with prior art of the present invention is: owing to increase roll extrusion on original technology, like this by hobboing cutter to after the connecting portion roll extrusion, the fineness of connecting portion improves more than 95%, cylindricity also improves greatly, make bearing and rotor element precision-fit, prolong the life-span of traction machine, make transmission efficiency improve.
Description of drawings
Fig. 1 is the structural representation of elevator traction machine rotor element.
Fig. 2 is the structural representation of A-A among Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
As depicted in figs. 1 and 2, a kind of elevator traction machine rotor element comprises rotor element body 1, the connecting portion that is provided with connection bearing 2 on rotor element body 1 and a plurality of screwed hole 3.
Concrete processing technology is as follows:
One, boring: holed in the rotor element surface, select the cutter of different-diameter as requested;
Two, finish turning: earlier finish turning is carried out on rotor element body 1 inside and outside surface, again the connecting portion on the rotor element body 12 is carried out finish turning, surplus is 0.025mm-0.03 mm;
Three, roll extrusion: adopt cylindrical hobboing cutter to be rolled into desired precision the connecting portion behind the finish turning 2, not only surface roughness moment just can reach Ry0.1-0.8 μ m by the connecting portion of rolling and processing, and machined surface sclerosis later stage wearability is improved, and fatigue strength has also increased by 30% simultaneously;
Four, tapping: the screwed hole 3 to boring carries out tapping.
So-called connecting portion 2 is meant the position that rotor element body 1 is connected with bearing among the present invention.
Comprehensively above-mentioned, embodiment among the present invention is owing to adopt cylindrical hobboing cutter that connecting portion 2 is carried out roll extrusion, tradition has increased the contact area that adds man-hour with lathe tool turning so relatively, the fineness of product has obviously been improved, the density and hardness at connecting portion 2 places has also all had remarkable improvement, by the connecting portion 2 of rolling and processing not only surface roughness moment just can reach Ry0.1-0.8 μ m, and machined surface sclerosis later stage wearability is improved, fatigue strength has also increased by 30% simultaneously.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
