Summary of the invention
The utility model technical problem to be solved is that a kind of front end structure that can make the vehicular compressed machine that compressor operation is steady, vibration is little is provided to above-mentioned existing technology present situation; Also make the shaft seal of main shaft of compressor stressed evenly in addition, reduce the wearing and tearing and the leakage of oil of shaft seal.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of front end structure of vehicular compressed machine; Comprise main shaft, belt pulley, friction disk, reach and the coaxial magnet yoke ring that sets and be provided with coil in it of main shaft; It is characterized in that: also comprise the front cover on the body that is fixed on compressor; Said front-end of spindle passes and exposes outside front cover, is equipped with clutch shaft bearing and shaft seal between the inner chamber of main shaft and front cover, and said magnet yoke ring is fixed on the front cover; Said belt pulley rotates on the outer circumferential face that is supported on the front cover that exposes outside body freely via second bearing; And radially surround said magnet yoke ring, said friction disk be connected the main shaft outer end and can and main shaft rotate together, the interior edge face of friction disk and Pulley shaft to the exterior edge face be oppositely arranged; The outer end of said main shaft is fixed with spring sheet, and this spring sheet and said friction disk are fixed.
The outer end of above-mentioned main shaft is connected with spline housing through spline, and said friction disk is set on the spline housing, and said spring sheet is fixed on this spline housing front-end face through pressing plate, circumferentially then being fixed together through screw and said friction disk of this spring sheet.This structure is convenient to friction disk and spring sheet are assembled on the main shaft.
Above-mentioned pressing plate presses solidly the front end at main shaft through the lock bolt that is threaded in the main shaft outer end, and pad is provided with elastic washer between the front-end face of pressing plate and main shaft.Through the effect of pressing plate and elastic washer, can be with friction disk and spring sheet firm fixation at front-end of spindle.
Be provided with backing plate between the head of above-mentioned lock bolt and the pressing plate exterior edge face.Backing plate can increase the area of contact with pressing plate, and lock bolt can be connected with main shaft is more firm through backing plate.
Above-mentioned second bearing through the hole in the endoporus that is arranged on belt pulley with back-up ring, the omoplate that is fixed on the shaft block ring on the front cover that exposes outside body and is arranged in the endoporus of belt pulley retrains the endoporus of belt pulley.
Above-mentioned front cover has outward flange, and the front-end face of this outward flange and body is fitted, and fixes through the front-end face of bolt and body.
The front end mask of above-mentioned belt pulley is provided with many grooves.Groove can increase the frictional force between friction disk and the belt pulley.
Compared with prior art; The advantage of the utility model is: because the weight of belt pulley is born by front cover through second bearing; Reduced main shaft because the caused circular runout of unbalanced force that the belt pulley rotation produces; Make compressor operating steadily, reduce vibration; Overcome simultaneously owing to the tension force that connects the driving belt between motor and the belt pulley causes main shaft deflection to produce the radial force to main shaft, thereby improve the uniformity coefficient of shaft seal, reduce shaft sealing wearing and tearing and leakage of oil the radial force of main shaft external diameter.
