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 the engine accessory power rating power train, specifically a kind of processing method of engine crankshaft damper pulley wheel hub of band edge face mouse fluted disc.
Background technology
Electronic engine management system is made up of sensor, electronic control unit ECU (Electronic Control Unit) and actuator.Sensor is the form input electronic control unit ECU of the working status parameter of engine with electronic signal and data; Electronic control unit ECU compares the setting value in input signal and the memory; Send corresponding signal instruction to systems such as fuel oil supply system, ignition system, air inlet and exhausts then, make engine performance optimum working performance.Sensor is generally gathered signal through the signal panels that are assembled together with damper pulley.Along with developing of automobile industry, increasingly high to the precision of sensor acquisition signal, this has also just proposed increasingly high requirement to damper pulley and the terminal synchronous operation of bent axle.Existing damper pulley generally leans on bolt and bent axle end to tighten together, in case after assembling and debugging were accomplished, bolt just can not have loosening, otherwise can have a strong impact on the precision of signals collecting.The terminal assembling of existing damper pulley and bent axle; Generally connect and prevent relative slip through key; The assembling that key connects is comparatively complicated, and the thickness to the damper pulley centre bore has proposed very high requirement simultaneously, and this just requires damper pulley must adopt the cast iron manufacturing.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 terminal synchronous operation of bent axle, can not effectively reach and the terminal easy assembling of bent axle.
Summary of the invention
Technical problem to be solved by this invention is the defective to prior art, and a kind of processing method of engine crankshaft damper pulley wheel hub of band edge face mouse fluted disc is provided, and it all adopts the spinning process manufacturing; Practice thrift material, reduced man-hour, reduced cost; Adopt end face mouse fluted disc to replace key to connect simultaneously; Improve the precision of signals collecting, prevented relative slip again, reduced assembly difficulty.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: at first on circle metal plate material, be spun to topmost end face mouse fluted disc through the end face rotary pressure technology; Then through further spinning, machined and blank operation; Finally process engine crankshaft damper pulley wheel hub, concrete steps are following:
(1) on round metal metal plate material, processes end face mouse fluted disc A with the end face rotary pressure technology;
(2) process column fitting surface B with rotary pressure technology in the outside of end face mouse fluted disc A;
(3) on the outer adradialia of column fitting surface B, process curved surface C with rotary pressure technology;
(4) on the blank cylindrical that above-mentioned operation obtains, process many wedges tooth D with rotary pressure technology;
(5) process the annular fitting surface E that has anti-skidding convexity in the inboard of many wedges tooth D with mach method;
(6) on spoke, go out fabrication hole and installing hole F.
20 ° of 17 mouse teeth that are uniformly distributed with are arranged on the wherein said end face mouse fluted disc A, and wherein the mouse tooth on 360 ° of peripheries has a disappearance.
The present invention has end face mouse tooth, and tightr with the interlock of bent axle afterbody, transmission is more accurate, and it is bigger to transmit moment of torsion; The present invention simultaneously all adopts spinning process, and manufacturing process is simple, light weight, 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 simultaneously is the integral type manufacturing, does not need other bindiny mechanism, saves the space, simple installation.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done and to further describe:
Like Fig. 1, shown in Figure 2; Product processed of the present invention comprises that end face mouse fluted disc A, column fitting surface B, many wedges tooth D, inwall have annular fitting surface E, installing hole and the fabrication hole F of anti-skidding convexity; 20 ° of 17 mouse tooth G that are uniformly distributed with are arranged on the wherein said end face mouse fluted disc A, and wherein the mouse tooth on 360 ° of peripheries has a disappearance H.
Processing method of the present invention is: at first on circle metal plate material, be spun to topmost end face mouse fluted disc through the end face rotary pressure technology; Then through further spinning, machined and blank operation; Finally process engine crankshaft damper pulley wheel hub finished product, concrete steps are following:
