A kind of antiseize device is applied on the chain sprocket drive, and this driving device comprises transmission shaft, axle sleeve, be sheathed on the sprocket wheel on the described axle sleeve and be positioned at chain on the described sprocket wheel; Described sprocket wheel is rotating to be fixed on the described axle sleeve; At least one side is provided with groove on the described sprocket wheel, is embedded with friction lining in the described groove; Described axle sleeve is provided with and is used for elastic pressure parts that described friction lining is compressed, and described friction lining and the equal fixed cover of described elastic pressure parts are located on the described axle sleeve, and described elastic pressure parts is consistent with the quantity of described friction lining.
Preferably, the both sides of described sprocket wheel are provided with groove.
Preferably, described elastic pressure parts is a bowl type structure.
Preferably, also comprise and be used for described sprocket wheel is positioned latching device on the described axle sleeve.
Preferably, described latching device is the jam nut that is rotatably connected in described axle sleeve one end.
Preferably, the both sides of described friction lining are provided with lines or the salient point that is used to increase friction.
The disclosed antiseize device of the utility model, friction lining is set on sprocket wheel, by the elastic pressure parts that is fixedly set on the axle sleeve friction lining and sprocket wheel are compressed, effect drive sprocket wheel by friction force rotates with axle sleeve, when load is excessive, friction force is less than the application force of load, transmission shaft still can drive axle sleeve, friction lining and elastic element and rotate, but sprocket wheel is motionless, avoided the damage or the motor overload of driving device to burn, guarantee the service life of driving device, reduce production, maintenance, handling cost, enhance productivity.

The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of antiseize device, avoid sprocket transmission device to damage, reduce production, maintenance, handling cost, guarantee the purpose of production efficiency to reach.
As Figure 1-3, a kind of antiseize device is applied on the chain sprocket drive, and this driving device comprises transmission shaft 11, axle sleeve 12, be sheathed on the sprocket wheel 13 on the axle sleeve 12 and be positioned at chain (not looking out) on the sprocket wheel 13; Sprocket wheel 13 rotating being fixed on the axle sleeve 12; Both sides on the sprocket wheel 13 are provided with groove 14, are embedded with friction lining 15 in the groove 14; Axle sleeve 12 is provided with and is used for elastic pressure parts 16 that friction lining 15 and sprocket wheel 13 are compressed, and friction lining 15 is located on the axle sleeve 12 with elastic pressure parts 16 equal fixed covers, and elastic pressure parts 16 is consistent with the quantity of friction lining 15.Motor (not looking out) drives transmission shaft 11 and rotates, axle sleeve 12 drive fixed covers are located at friction lining 15 and the elastic pressure parts 16 and transmission shaft 11 run-in synchronisms on the axle sleeve 12 simultaneously, because elastic pressure parts 16 compresses friction lining 15 and sprocket wheel 13, by between friction force drive sprocket wheel 13 and rotate.When keeping off load force greater than friction force, transmission shaft 11 drives elastic pressure parts 16 and friction lining 15 running as usual, and sprocket wheel is motionless, has avoided preventing that owing to the damage of overload to driving device motor overload from burning.In addition, groove 14 also can only be provided with a side, enough drives the sprocket wheel running as long as guarantee friction force, and quantity does not limit.
