The belt pulley cushion rubber is pressed into frock
Technical field
The utility model relates to a kind of belt pulley cushion rubber and is pressed into frock.
Background technology
Bent axle is an elasticity of torsion system of motor car engine; Belt pulley is mounted in the critical function spare of crankshaft front end; Its major function is that the bent axle to engine plays cushioning effect; Be embodied in the windup-degree that reduces bent axle, the damping effect quality of a belt pulley has determined the length in service life of its bent axle.
If press-fiting and bond firm inadequately between belt pulley cushion rubber and the wheel hub; Along with the rotary inertia of crankshaft-flywheel is big and produce torsional shaking; When vibration frequency became multiple with the shake frequency certainly of bent axle, the vibrations of bent axle were just more violent, thereby caused engine power impaired easily; The rigidity of bent axle, intensity also can correspondingly descend, and have directly influenced the service life of bent axle and even engine.Yet traditional belt wheel cushion rubber method of press-fitting roughly is divided into two kinds: (1) weight impacts belt pulley and is pressed into, and this traditional method is pounded pulley rim on the one hand easily and caused belt pulley to damage; Can not impact point be stabilized on the predetermined axial line on the other hand, be difficult to be in place; Low and the hazardous of manually-operated efficient on the one hand again.(2) use traditional belt wheel cushion rubber to be pressed into frock and be pressed into, traditional be pressed into the tool structure complicacy, cost is high, it is low and be pressed into intensity and do not reach requirement to be pressed into efficient.
The utility model content
The purpose of the utility model is to solve the deficiency that existing belt pulley cushion rubber is pressed into frock; Provide a kind of novel belt pulley cushion rubber to be pressed into frock, overcome conventional belt wheel cushion rubber and be pressed into that tool structure complicacy, cost are high, to be pressed into efficient low and be pressed into shortcoming such as insufficient strength.
The purpose of the utility model realizes through following technical scheme: the belt pulley cushion rubber is pressed into frock, and it comprises fixed head, location-plate, Connection Block, gland, outer guide sleeve a, outer guide sleeve b, interior fairlead, locating shaft, wheel hub, rubber ring, outer ring, base and holder, and fixed head is provided with hydraulic press; Fixed head is fixed on the location-plate through screw; Connection Block is provided with groove, and location-plate is arranged in the groove of Connection Block, and the center of Connection Block is connected with gland; Gland is provided with briquetting; Gland is connected through screw with outer guide sleeve a, and the other end of outer guide sleeve a is connected with locating shaft, and the other end of locating shaft is fixedly connected on the holder; Locating shaft is provided with interior fairlead near the end of outer guide sleeve a, and fairlead was near a side of holder in wheel hub was arranged on; The both sides of Connection Block connect spring conductor rod; The other end of spring conductor rod is fixedly connected with outer guide sleeve b; Be provided with spring between spring conductor rod and the outer guide sleeve b, the outside of outer guide sleeve b is provided with base, and outer guide sleeve b is provided with the outer ring near a side of holder; Rubber ring is arranged between wheel hub and the outer ring, and base through screws is fixed on the holder.
The described hydraulic press of the utility model is fixed on the fixed head through flange arrangement.
Be provided with the slit between fairlead and the outer guide sleeve b in the utility model is described, briquetting and rubber ring cooperate with the slit respectively.
The beneficial effect of the utility model is: provide a kind of simple in structure, production cost is low, the belt pulley cushion rubber is pressed into the high belt pulley cushion rubber of efficient and presses people's frock, it is big that it also has the intensity of being pressed into, effective characteristics such as service life that prolonged belt pulley and bent axle.
