Input end assembly of mechanical supercharger

Abstract

The invention provides an input end assembly of a mechanical supercharger, which is applied to the field of mechanical superchargers. The input end assembly of the supercharger comprises a belt pulley (2). A front cover plate (20) and a bearing plate at the input end of the mechanical supercharger form a hollow cavity structure, an input shaft (3) and a driving shaft (12) are installed in a hollow cavity and are connected by a shaft coupling (15), a driving gear (13) is sleeved and installed on the driving shaft (12), a driven gear (14) is sleeved and installed on a driven shaft (16), the driving gear (13) and the driven gear (14) are engaged, the input shaft (3) is fixedly connected with the belt pulley (2), and a decorative cover (1) is installed on the other face of the belt pulley (2) which is connected with the input shaft (3). By the technical scheme, the coaxiality of the driving shaft and the input shaft when the supercharger is in different working conditions can be ensured, the running stability of the supercharger is enhanced, and the condition that the lubricating oil of the supercharger is free from maintenance perpetually is realized.

Description

Technical field [0001] The present invention relates to the field of mechanical superchargers. More specifically, the present invention relates to a mechanical supercharger input end assembly. Background technique [0002] Without increasing the cylinder volume, engine supercharging technology can greatly increase the power and torque of the engine, so it is getting more and more attention. The supercharging technology of automobile engine mainly includes exhaust gas turbocharging and mechanical supercharging. Compared with exhaust gas turbocharging, superchargers have advantages such as good transient response characteristics, simple use and maintenance, and long life, so they have gradually been widely used in the engine industry. [0003] The working principle diagram of the traditional supercharged and intercooled engine is attached Image 6 Shown. The supercharger 39 has a pair of driving rotor 35 and a driven rotor 36 meshing with each other. The two rotors are fixed on the ...

AI Technical Summary

Problems solved by technology

Since the output torque of the vehicle engine is not completely stable and constant, but pulsating, this will cause a pair of timing gears in the supercharger to rebound, accompanied by the sound of clicking, so the vibration and vibration of the existing supercharger Mechanical noise is loud

In addition, the high-speed rotation of the gears and bearings that mesh with each other needs to ensure that the gears and bearings are fully lubricated, otherwise the reliability and durability of the supercharger will be seriously affected; The performance is not good, and oil leakage often occurs, which requires regular replenishment of lubricating oil for the supercharger during normal maintenance

This not only increases maintenance costs, but also puts the durability of the supercharger at potential risk
