Abstract
The utility model discloses a guide driven device for loader-digger transmission. Through the connection of a transmission chain and a driving chain wheel, the guide driven device comprises a guide wheel shaft (2), the guide wheel shaft (2) is matched with a guide wheel (6) through a sliding bearing (5), stop screws (7) are arranged in the circumferential direction of the sliding bearing (5), limiting shaft sleeves (10) are arranged at the two ends of the sliding bearing (5), a check ring (8) and a framework oil seal (4) are arranged between the two limiting shaft sleeves (10), and set screws (9) are arranged on the limiting shaft sleeves (10). An oil cup (1) is arranged at one end of the guide wheel shaft (2), and an O-shaped seal ring (3) is further arranged between the guide wheel shaft (2) and the limiting shaft sleeves (10). The phenomenon that a chain is clamped due to the fact that tooth scrambling occurs to driven meshing in a chain transmission process is eliminated, the performance of preventing non-lubrication foreign matter from entering the device is improved, the lubrication function of lubricating grease on the bearing is guaranteed, the structural style of lubricating the bearing is changed, and the abrasion resistance of the bearing is improved.
Description
Technical field
The utility model relates to a kind of structure of chain conveying means, particularly follower.
Background technique
At present, be applied to excavate transloader loading conveying trough quarrel and expect that the kind of drive of Conveying chains mainly combines with drive sprocket and driven sprocket, this is the non-precision drive of low speed, has following two kinds of problems:
1 with Transmitted chains roller when engagement, cause chain and the stuck clamping stagnation chain phenomenon that occurs of follower cover plate because robbing the tooth top chain.Simultaneously, in the chain transmission process, have the circular runout phenomenon, and the bearing capacity of rolling bearing roller is limited.
Poor sealing performances such as 2 waterproof and dustproofs, non-lubricated foreign matter easily infiltrates, and has had a strong impact on the lubrication of lubricating grease to bearing, and has reduced the working life of bearing.Therefore, exist to change shortcomings such as frequency height, labor intensity are big, maintenance cost height.
Summary of the invention
The technical problems to be solved in the utility model is: be provided for the guiding driven device that loader-digger transmits, driven engagement occurs in the elimination chain transmission process and rob the clamping stagnation chain phenomenon that tooth causes, improve the performance that anti-non-lubricated foreign matter enters, guarantee that lubricating grease is to the lubrication of bearing, change the structural type of lubricating bearings, improve its wear resistance.
The technical solution of the utility model is: a kind of guiding driven device for the loader-digger transmission, be connected with drive sprocket by drive chain, described guiding driven device comprises guide wheel shaft, guide wheel shaft cooperates with upper saw pulley by sliding bearing, and sliding bearing circumferentially has lock screw, and the sliding bearing two ends are spacing axle sleeve, back-up ring and outside framework oil seal are arranged between the two, position-limited shaft has put Cock screw, and guide wheel shaft one end has lubricating cup, also has the O RunddichtringO between guide wheel shaft and the spacing axle sleeve.
Described upper saw pulley is anodontia upper saw pulley, and the anodontia upper saw pulley kind of drive has been avoided because robbing the clamping stagnation chain problem that tooth or top chain situation produce.
Adopt sliding bearing (material is tin bronze) structure, can carry bigger radial load.
Adopt outside framework oil seal section sealing configuration, prevent the infiltration of non-lubricated foreign matter, guarantee lubricating grease lubricating bearing.
Employing is installed spring preloading device additional at the adjusting screw rod of drive sprocket, increases the tension force of chain, thereby increases the frictional force between upper saw pulley and the chain roller, prevents that the chain of taking off is arranged in the chain transmission process, phenomenon such as jumping chain.
The utility model eliminated occur in the chain transmission process rob the clamping stagnation chain phenomenon that tooth causes because of driven engagement, improved the performance that anti-non-lubricated foreign matter enters, guarantee that lubricating grease to the lubrication of bearing, by changing the structural type of lubricating bearings, improves its wear resistance.
