Abstract
The invention relates to a processing method for engine crankshaft vibration damping pulley wheel hub with end surface rat fluted disc. The specific steps are as follows: (1) processing an end surface rat fluted disc A on the metal circular sheet material by using end surface spinning technology; (2) processing a cylindrical assembling surface B at the outer side of the end surface rat fluted disc A by the spinning technology; (3) processing a curve C on the outer side radiation plate of the cylindrical assembling surface B by the spinning technology; (4) processing a multi-wedge tooth D on the blank excircle obtained in above procedures by the spinning technology; (5) processing an annular assembling surface E with an anti-slide bulge at the inner side of the multi-wedge tooth D by machining method; (6) punching a technological hole 1 and an installing hole F on the spoke. The processing method for engine crankshaft vibration damping pulley wheel hub with end surface rat fluted disc has the end surface rat tooth to be tightly engaged with the crankshaft tail, thus the transmission is precise and the transfer torque is larger; meanwhile, by fully using the spinning technology, the processing method is simple in manufacturing technique, convenient in installation and low in cost; at the same time, the processing method has small dynamic balance quantity, lowers noise of the engine and improves service life of the crankshaft.
Description
Technical field
The present invention relates to crank pulley in engine accessory power rating power train, specifically a kind of processing method of the belt pulley for damping vibration of crankshaft of engine wheel hub with end face mouse fluted disc.
Background technology
Electronic engine management system is comprised of sensor, electronic control unit ECU (Electronic Control Unit) and actuator.Sensor is the form input electronic control unit ECU with electronic signal and data the working status parameter of engine, electronic control unit ECU contrasts the setting value in input signal and memory, then to systems such as fuel oil supply system, ignition system, air inlet and exhausts, send corresponding signal instruction, make engine performance optimum working performance.Sensor is generally by the signal panels collection signal being assembled together with damper pulley.Along with the development of auto industry, more and more higher to the precision of sensor collection signal, this has also just proposed more and more higher requirement to the synchronous operation of damper pulley and bent axle end.Existing damper pulley generally tightens together by bolt and bent axle end, once after assembling and debugging complete, bolt just can not have loosening, otherwise can have a strong impact on the precision of signals collecting.Existing damper pulley and the assembling of bent axle end, generally by key, connect and prevent relative sliding, the assembling that key connects is comparatively complicated, the thickness of damper pulley centre bore has been proposed to very high requirement simultaneously, and this just requires damper pulley must adopt cast iron manufacture.Shen Qing Publication day is the engine snubber belt pulley (Fig. 1) that patent of invention that July 20, application publication number in 2011 are CN 102128246A has been announced a kind of mould pressing, but this invention can not guarantee the precision with the synchronous operation of bent axle end, can not effectively reach the easy assembling with bent axle end.
Summary of the invention
Technical problem to be solved by this invention is the defect for prior art, a kind of processing method of the belt pulley for damping vibration of crankshaft of engine wheel hub with end face mouse fluted disc is provided, it all adopts spinning process manufacture, save material, reduced man-hour, reduced cost, adopt end face mouse fluted disc to replace key to connect simultaneously, improved the precision of signals collecting, prevented from again relative sliding from having reduced assembly difficulty.
For solving the problems of the technologies described above, the technical solution used in the present invention is: first by end face rotary pressure technology, on circle metal plate material, be spun to topmost end face mouse fluted disc, then by further spinning, machined and blank operation, finally process belt pulley for damping vibration of crankshaft of engine wheel hub, concrete steps are as follows:
(1) with end face rotary pressure technology, on round metal metal plate material, process end face mouse fluted disc A;
(2) with rotary pressure technology, in the outside of end face mouse fluted disc A, process column fitting surface B;
(3) with rotary pressure technology, on the outer adradialia of column fitting surface B, process curved surface C;
(4) on the blank cylindrical obtaining in above-mentioned operation with rotary pressure technology, process many wedges tooth D;
(5) by mach method, in the inner side of many wedges tooth D, process the annular fitting surface E with anti-skidding projection;
(6) in spoke upper punch, go out fabrication hole and installing hole F.
On wherein said end face mouse fluted disc A, have 20 ° of 17 uniform mouse teeth, wherein the mouse tooth on 360 ° of peripheries has a disappearance.
The present invention is with end face mouse tooth, and tightr with the interlock of bent axle afterbody, transmission is more accurate, and transmitting torque is larger; The present invention simultaneously all adopts spinning process, and manufacturing process is simple, and quality is light, and material is economized, and cost is low; Computing ballance correction of the present invention is little simultaneously, has reduced the noise of engine, the life-span of having improved bent axle; The present invention is simultaneously integral type manufacture, does not need other bindiny mechanism, saves space, simple installation.
