Abstract
The utility model relates to an engine crankshaft damping belt pulley hub with an end face mouse tooth disc. The engine crankshaft damping belt pulley hub comprises a columnar mounting surface arranged on the hub, multiple wedge-shaped teeth and an annular mounting surface of which the inner wall is provided with anti-slip bosses. The engine crankshaft damping belt pulley hub is characterized in that the middle of the hub is provided with the end face mouse tooth disc; the end face mouse tooth disc and the columnar mounting surface are combined into a whole; the multiple wedge-shaped teeth and the annular mounting surface are combined into a whole; the columnar mounting surface and the annular mounting surface of which the inner wall is provided with anti-slip bosses are connected into a whole through a curved spoke plate; a mounting hole and a process hole are distributed on the curved spoke plate; (18-1=)17 mouse teeth are uniformly distributed on the end face mouse tooth disc in 20 degrees; and a mouse tooth is missing on the 360-degree circumferential surface. The hub is provided with the end face mouse teeth, is tightly engaged with the tail of the crankshaft, and is accurate in transmission and high in transmission torque; meanwhile, the hub is low in dynamic balance, the noise of the engine is reduced, and the service life of the crankshaft is prolonged; and moreover, the hub is integrally manufactured, other connecting mechanisms are not required, the space is saved, and the hub is easily and conveniently mounted.
Description
Technical field
The utility model relates to the annex in the engine driving system, specifically a kind of engine crankshaft damper pulley wheel hub of band edge face mouse fluted disc.
Background technique
Electronic engine management system is made up of sensor, electronic control unit ECU (Electronic Control Unit) and final controlling element.Sensor is the form input electronic control unit ECU of the working status parameter of motor with electronic signal and data; Electronic control unit ECU compares the setting value in input signal and the storage; Send corresponding signal instruction to systems such as fuel oil supply system, ignition system, air inlet and exhausts then, make motor performance optimum working performance.Sensor is generally gathered signal through the signal panel 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 slide relative through key; The assembling that key connects is comparatively complicated, and the thickness to the damper pulley center hole has proposed very high requirement simultaneously, and this just requires damper pulley must adopt the cast iron manufacturing.Notice of authorization day is an engine snubber belt pulley (Fig. 1) of on August 31st, 2011, notice of authorization number having announced a kind of mould pressing for the utility model patent of CN 201953952U; But this model utility 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
The utility model technical problem to be solved is the defective to existing technology; A kind of engine crankshaft damper pulley wheel hub of band edge face mouse fluted disc is provided, and it adopts end face mouse fluted disc to replace key to connect, and has improved the precision of signals collecting; Prevent slide relative again, reduced assembling difficulty.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: it comprises that wheel hub is provided with the annular mating face that column mating face, many wedges tooth and inwall have anti-skidding convexity; It is characterized in that: the centre of wheel hub is provided with end face mouse fluted disc; End face mouse fluted disc and column mating face are combined as a whole, and many wedges tooth and annular mating face are combined as a whole.
The utility model technological scheme preferably is: the annular mating face that column mating face and inwall have anti-skidding convexity connects as one through the curved surface disc, is laid with mounting hole and auxiliary hole on the curved surface disc; 17 mouse teeth of 20 ° of (18-1=) that are uniformly distributed with are arranged on the end face mouse fluted disc, and wherein the mouse tooth on 360 ° of circumferential surfacies has a disappearance.
The utility model wheel hub has end face mouse tooth, and it and the interlock of bent axle afterbody are tightr, and transmission is more accurate, and transmitting torque is bigger; The utility model computing ballance correction is little simultaneously, has reduced the noise of motor, the life-span of having improved bent axle; It adopts the integral type manufacturing, does not need other bindiny mechanism, saves the space, simple installation.
