Problems solved by technology

[0003] The invention provides a bridge tooth structure, which mainly solves the problem that the rolling bearings of the existing oil pump inside the Weichai engine will be worn and damaged after being used for a period of time, and once worn and damaged, the power of the oil pump will be reduced. The transmission is interrupted, so that the pressure lubricating oil of the engine is lost, which in turn causes serious damage to the engine

Embodiment

[0010] Example: such as figure 1 As shown, a bridge tooth structure in this example includes a bridge gear (1), which is characterized in that a bushing (2) is embedded inside the bridge gear (1), and the bushing ( 2) A fixed shaft (3) is inserted inside, and the fixed shaft (3) is also provided with an oil channel (6). One end of the oil channel (6) communicates with the main oil circuit inside the engine, and the other One end communicates with the shaft end surface of the fixed shaft (3), and the middle part of the fixed shaft (3) is provided with a plurality of screw holes (4), and a set of screw rods (5) are inserted in the plurality of screw holes (4) . Because the bridge teeth of the oil pump inside the Weichai engine adopt the positioning method of the shaft and the bushing, and the mutual rotation contact surface of the shaft and the bushing is lubricated with oil, so that the bridge teeth of the oil pump can be Long-term high-load operation without wear and tear en...

Abstract

The invention relates to a carrier gear structure. The carrier gear structure comprises a carrier gear. The carrier gear structure is characterized in that a shaft sleeve is embedded in the carrier gear, a fixing shaft is inserted in the shaft sleeve, a plurality of screw holes are formed in the middle of the fixing shaft, and a set of screw rods are inserted in the screw holes. According to the carrier gear structure, due to the fact that a shaft and shaft sleeve positioning manner is adopted in a carrier gear of an oil pump in a Weichai engine, and an oil lubricating manner is adopted on contact faces, mutually rotating, of the shaft and the shaft sleeve, the carrier gear of the oil pump can run with the high load for a long term but not abrade; and the long-term normal work of the oil pump is guaranteed, and the service life of the engine is guaranteed.

Description

technical field [0001] The invention relates to the field of Weichai engines, in particular to a bridge tooth structure. Background technique [0002] The oil pump inside the Weichai engine transmits power through a bridge gear. The existing bridge gear uses a gear on the outside, a ball bearing is installed inside the gear, and a shaft inserted into the ball bearing is used to transmit power. This structure will cause wear and damage to the rolling bearing after a period of use, and once the wear is damaged, the power transmission of the oil pump will be interrupted, the pressure lubricating oil of the engine will be lost, and the engine will be seriously damaged. , the present invention well solves the existing technical problems. Contents of the invention [0003] The invention provides a bridge tooth structure, which mainly solves the problem that the rolling bearings of the existing oil pump inside the Weichai engine will be worn and damaged after being used for a pe...
