The invention relates to an oil pump device in deflection-free drive as well as a crane. The oil pump device in deflection-free drive comprises an oil pump, an oil pump support, an oil pump auxiliary support, a receiving disc, a pressing disc, a drive shaft and a power takeoff, wherein the oil pump support is welded to a frame; the head part of the oil pump is pressed by the pressing disc, and is connected with the receiving disc; the head part of the oil pump is fixedly connected to the oil pump support; one end of the drive shaft is fixedly connected with the receiving disc; the other end of the drive shaft is fixedly connected with the power takeoff; one end of the oil pump auxiliary support is fixedly connected with the tail part of the oil pump, and the other end of the oil pump auxiliary support is fixedly connected to the frame; a shaft axis of the oil pump is coincident with that of the drive shaft. According to the oil pump device and the crane disclosed by the invention, the stress situation of an oil pump shaft head can be improved, so that the service life of the oil pump shaft head is prolonged, and the problem of installation and configuration in a small space is solved.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to an oil pump device and a crane driven without deflection angle. Background technique [0002] The gearbox is a box-shaped part equipped with a speed change mechanism, which is divided into manual and automatic. The manual transmission is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations, while the automatic transmission is composed of a hydraulic torque converter, a planetary gear and a hydraulic control system, and is achieved through hydraulic transmission and gear combination. Variable speed and torque. It has the following three functions: [0003] ①Change the transmission ratio and expand the range of driving wheel torque and speed to adapt to changing driving conditions, such as starting, accelerating, uphill, etc.; [0004] ② On the premise that the engine speed remains unchanged, the car can run...
