Abstract

The utility model belongs to the technical field of transmission systems, and particularly relates to a permanent-magnet cushion pulley. In the utility model, bearings are arranged on a spindle to support and connect the pulley; a bearing is arranged on a shaft lining of the pulley to support and connect a fixed base; and the fixed base is installed on a bracket. The permanent-magnet cushion pulley is characterized in that a cushion disc is arranged inside a cavity of the pulley and connected with a spindle spline; permanent magnets are respectively embedded in the corresponding positions of the pulley and the cushion disc; more than two open through grooves are uniformly distributed on the circumference of the cushion disc; cushion pads are arranged in the open through grooves; and the cushion pads are fixed on the inner surface of the cavity of the pulley through bolts. The utility model has the advantages as follows: the synchronous and stable running of the pulley is driven by an engine or a motor so as to prolong the service life of the engine.

Description

Permanent magnetism check strap wheel

Technical field: the utility model belongs to the transmission system technical field, is specifically related to a kind of permanent magnetism check strap wheel.

Technical background: more and more higher along with auto manufacturing technology constantly develops to the requirement of automotive service life, and existing belt pulley transmission is too big to the anti-force of motor when starting running, has shortened the working life of motor.

Summary of the invention: the purpose of this utility model provide a kind of stable, can reduce car noise, and motor is played the permanent magnetism check strap wheel of buffer function.

Technological scheme of the present invention is: a kind of permanent magnetism check strap wheel, and on main shaft, establish bearings and connect belt pulley, to establish bearings on the axle sleeve of belt pulley and be connected and fixed seat, fixed base is rack-mount; It is characterized in that: in the cavity of belt pulley, establish buffer disc; Buffer disc is connected with main spindle multiple spline; Inlay permanent magnet respectively on the mutual corresponding position of belt pulley and buffer disc; Be laid with two with the saturating groove of upper shed on the circumference of buffer disc, establish cushion pad in the saturating groove of opening, cushion rubber bumper is fixed by bolts on the belt pulley cavity inner surface.

Owing to adopt technique scheme, motor or driven by motor belt pulley rotate, and utilize the characteristic of the permanent magnet N utmost point and the S utmost point of belt pulley and buffer disc, and buffer disc is slowly turned round with belt pulley, and buffer disc drives spindle operation, and transmission of power is gone out; Because it is excessive to start the moment moment of torsion, buffer disc can not slippage occur synchronously with the belt pulley running, plays buffer function, when the saturating groove of the opening of buffer disc with after cushion rubber bumper contacts, belt pulley and buffer disc are locked; Thereby have the motor of making or the synchronous smooth operation of driven by motor belt pulley, thereby improved the advantage in the working life of motor.

Description of drawings: come the technical solution of the utility model is elaborated below in conjunction with the drawings and specific embodiments.Fig. 1 is a structural representation of the present utility model.Fig. 2 is the A-A sectional view of Fig. 1.Fig. 3 is the B-B sectional view of Fig. 1.

Embodiment: with reference to figure 1--Fig. 3.A kind of permanent magnetism check strap wheel is established bearing 2,3 support and connection belt pulleys 4 on main shaft 1, establish bearing 6 support and connection fixed bases 7 on the axle sleeve of belt pulley 4, and fixed base 7 is installed on the support 8; In the cavity of belt pulley 4, establish buffer disc 5; Buffer disc 5 is connected with main spindle multiple spline; Inlay permanent magnet 9,10 respectively on belt pulley 4 and the buffer disc 5 mutual corresponding positions; Be laid with two with the saturating groove of upper shed on the circumference of buffer disc 5, establish cushion pad 12 in the saturating groove of opening, cushion rubber bumper 12 is fixed by bolts on belt pulley 4 cavity inner surfaces; If buffer disc 5 is made for non-magnet_conductible material, between buffer disc 5 and permanent magnet 10, also establish soft iron 11 and get final product.In the present embodiment, be laid with 4 saturating grooves of opening on the circumference of buffer disc 5.
