Abstract
The utility model relates to a shock attenuation belt pulley group spare with the crankshaft, belt pulley group spare includes rotator, rubber circle, belt pulley, the rotator is the ladder ring -type, and one end is cyclic annular for the ladder of minor diameter end for the major diameter end other end promptly, the fixed cover of rubber circle is established on the outer disc of rotator major diameter end, the belt pulley is the ring form, and the middle part of its outer disc is equipped with the race, and the fixed cover of interior disc of belt pulley is established rubber circles, the utility model discloses simple structure, the preparation is convenient, encloses through rubber effectively to reduce bent axle and the vibrations volume of belt pulley when operateing, has protected the engine annex, has improved the job stabilization nature of engine annex.
Description
Technical field
The utility model belongs to Diesel Engine Technique Field, is specifically related to a kind of damper pulley assembly be connected with bent axle.
Background technique
At present, in the running, bent axle can produce periodically change and reverse and bending deflection multicylinder engine, thus produces torsional vibration and flexure vibrations.Crank pulley is connected with bent axle, and crank pulley is by the running of other engine accessory power ratings of belt drives, as generator, compressor etc.;
But the connection of existing crank pulley and bent axle is for being rigidly connected, the torsional vibration of bent axle and flexure vibrations can aggravate the wearing and tearing of crank pulley, thus affect the engine accessory power rating be connected with crank pulley, cause engine accessory power rating job insecurity.Shock momentum simultaneously because of bent axle is comparatively large, and also can aggravate the wearing and tearing with bent axle connected toothed wheel system, bent axle itself may cause fracture.
Model utility content
For solve existing crank pulley to be connected with bent axle produce vibrations, wearing and tearing, and cause the defects such as engine accessory power rating job insecurity, the utility model devises a kind of damper pulley assembly be connected with bent axle.
The damper pulley assembly be connected with bent axle, described pulley assembly comprises solid of rotation 3, rubber ring 2, belt pulley 1;
Described solid of rotation 3 in stepped annular, the stepped annular of smaller diameter end 32 that to be namely the larger diameter end the other end be in one end;
Described rubber ring 2 fixed cover is located on the periphery of described solid of rotation 3 larger diameter end;
Described belt pulley 1 is in circular, and the middle part of its periphery is provided with belt grooves 12, and the inner headed face fixed cover of belt pulley 1 is located on described rubber ring 2;
During work, the smaller diameter end 32 of solid of rotation 3 is fixedly connected on the end of bent axle 5.
The periphery projection of described solid of rotation 1 has a circle bulge loop 31, and the inner headed face depression of belt pulley 3 has the groove 11 corresponding with described bulge loop 31; Rubber ring 2 laminating is set on the periphery of solid of rotation 1, and bulge loop 31 and groove 11 realize the axially locating to rubber ring 2.
The thickness of described rubber ring 2 is 3mm.
Described belt pulley 1 is wedge belt wheel.
Advantageous Effects of the present utility model:
The utility model is connected with bent axle by solid of rotation, is provided with rubber ring between crank pulley and solid of rotation, and on solid of rotation, is provided with bulge loop, is provided with groove over pulleys carried;
The utility model structure is simple, easy to make, can effectively reduce bent axle and belt pulley shock momentum in the running, protect engine accessory power rating, improve the working stability of engine accessory power rating by rubber ring; Improve the performance of car load, handling and reliability simultaneously; Bulge loop on solid of rotation and the groove on belt pulley have carried out axial, radial location to rubber ring, make rubber ring not easily landing in operation process, extend working life, reduce the incidence rate of accident.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model pulley schematic diagram.
Sequence number in upper figure: belt pulley 1, groove 11, belt grooves 12, rubber ring 2, solid of rotation 3, bulge loop 31, smaller diameter end 32, belt 4, bent axle 5.
Embodiment
See Fig. 1, a kind of damper pulley assembly be connected with bent axle, described pulley assembly comprises solid of rotation 3, rubber ring 2, belt pulley 1;
Described solid of rotation 3 in stepped annular, the stepped annular of smaller diameter end 32 that to be namely the larger diameter end the other end be in one end, the periphery projection of described solid of rotation 3 larger diameter end has a circle bulge loop 31;
The thickness of described rubber ring 2 is 3mm, and rubber ring 2 fixed cover is located on the periphery of described solid of rotation 3 larger diameter end;
Described belt pulley 1 is in circular, and belt pulley 1 is wedge belt wheel, and the middle part of belt pulley 1 periphery is provided with belt grooves 12, and the inner headed face depression of belt pulley 1 has the groove 11 corresponding with described bulge loop 31; The inner headed face fixed cover of described belt pulley 1 is located on described rubber ring 2, and bulge loop 31 and groove 11 realize the axially locating to rubber ring 2;
See Fig. 2, during work, the smaller diameter end 32 of solid of rotation 3 is fixedly connected on the end of bent axle 5; Other engine accessory power ratings are driven to operate by the belt 4 of configuration in the belt grooves 12 of belt pulley 1.
