Abstract
The utility model relates to a four-group eccentric shaft working device which belongs to an eccentric shaft working device of a road roller. Four groups of eccentric shaft working devices are arranged around a main drive shaft in a vibrating working wheel and on a circle taking the main drive shaft as the circle center. Every two eccentric shafts are spaced with 90 DEG. Four groups of eccentric shaft working devices are connected in parallel. Each eccentric shaft working device is provided with an eccentric shaft provided with fixed eccentric blocks and moving eccentric blocks. The side of the main drive shaft is provided with a drive mechanism. The working device with simple structure and large exciting force can be assembled into the working device for vibration, oscillation or combined vibration and oscillation by changing the combining modes of the fixed eccentric blocks and the moving eccentric blocks.
Description
The utility model relates to a kind of eccentric shaft equipment of road roller, four groups of eccentric shaft equipments that use on particularly a kind of road roller.
At present, the equipment of large-tonnage road roller, be in the vibration active wheel, final drive shaft to be installed, two groups of eccentric shaft equipments are installed on final drive shaft, the eccentric shaft equipment is that fixed eccentric block and movable eccentric block are installed on final drive shaft, two groups of eccentric shaft equipments and overlap with vibration active wheel center of circle line on same axis, and two groups of eccentric shaft equipments centres are connected in series by coupling.This equipment is subjected to its structural limitations exciting force little, is subjected to the restriction of bearing factor, and eccentric block can not unrestrictedly amplify, and service behaviour is low.
The purpose of this utility model is that four groups of eccentric shaft equipments that a kind of exciting force is big, service behaviour is high will be provided.
The purpose of this utility model is achieved in that in the vibration active wheel and around final drive shaft four groups of eccentric shaft equipments is installed, the eccentric shaft work clothes are equipped with eccentric shaft, fixed eccentric block and movable eccentric block are installed on eccentric shaft, transmission mechanism are arranged in the side of final drive shaft.
Transmission mechanism is in the end of final drive shaft master gear to be installed, master gear be connected from gear, be installed on the eccentric shaft from gear.
Transmission mechanism is that the end at final drive shaft is equipped with main pulley, is equipped with on eccentric shaft from belt pulley, is connected with synchronous belt at main pulley and between the belt pulley.
It is on the circumference in the center of circle that the eccentric shaft equipment is installed in the final drive shaft, interval 90 degree between two eccentric shafts, and four groups of eccentric shaft equipments are for being connected in parallel.
Owing to adopted such scheme, around final drive shaft four groups of eccentric shaft equipments are installed, bear the work of former one group of eccentric shaft equipment by four groups of eccentric shaft equipments, so employed bearing should not damage, and the output exciting force is big, performance height, the compound mode of change fixed eccentric block and movable eccentric block, promptly can change the working method of the vibration or the vibration of road roller, reach the purpose of this utility model.This equipment is simple in structure, and exciting force is big, and performance greatly improves, and by changing the compound mode of fixed eccentric block and movable eccentric block, promptly can be assembled into vibration, vibration, vibration and the equipment that vibrates and mix.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
