Abstract
The invention discloses an eccentric cam swivel bearing sleeve. According to the eccentric cam swivel bearing sleeve, the external diameter of the eccentric cam swivel bearing sleeve is composed of two circular columns with different center lines; the center line of an upper end part, which matches with an inner hole of a bevel gear wheel, and the center line of a lower end part, which slidingly matches with an inner hole of a straight lining are staggered. The eccentric cam swivel bearing sleeve is capable of eliminating additional impact loading, reducing vibration, reducing noise, and prolonging service life of gears.
Description
The invention belongs to a kind of eccentric cam running shaft bearing sleeve in a kind of machinery.
At present, the eccentric shaft bearing sleeve of existing a kind of machinery disintegrator, its external diameter is a cylindrical body, power by transmission shaft through bevel pinion oral instructions to bevel gear wheel, then driving cam axle sleeve rotation.Cam sleeve should be around same center line rotation with large cone pulley, but because the center line of straight lining has distance, cause gap between cam sleeve and straight lining, cause bevel gear wheel around former center line rotation, can only make circular movement take half of both gaps as radius.Obviously, this motion has destroyed this normal meshing condition to bevel gear.When its result causes disintegrator normally to work, on gear and transmission shaft, produce added impact load, and aggravated the wearing and tearing on Gear Contact surface, increased vibration and noise, reduced the life-span of gear.
The object of the invention is.A kind of normal meshing condition of bevel gear that guarantees is provided, eliminates added impact load and reduce vibration, reduce noise, extend the eccentric cam running shaft bearing sleeve of gear life.
The object of the present invention is achieved like this: the external diameter of its cam sleeve is made up of the cylindrical body of two sections of different center lines, its upper end section, match with the endoporus of bevel gear wheel position and lower end section, with the endoporus of the straight lining center line at the position distance that mutually staggers that is slidably matched.
Below in conjunction with embodiment and accompanying drawing thereof, the invention will be further described:
Fig. 1 is existing eccentric cam running shaft bearing sleeve fundamental diagram.
Fig. 2 is the A-A sectional view of Fig. 1.
Shown camshaft bearing sleeve, its external diameter upper end, figure stage casing is and the endoporus matching part of bevel gear wheel; Lower end, figure stage casing is and the endoporus of the straight lining position that is slidably matched.
Shown camshaft bearing sleeve, the cylindrical upper end of its external diameter, the center line of the endoporus section of joining of camshaft bearing sleeve and gearwheel and the lower end of camshaft bearing sleeve, the center line distance that staggers of section, value equal camshaft bearing sleeve and the gap between lining directly partly because disintegrator specification is motionless.
Shown on two sections of external cylindrical surfaces of figure, have a points of tangency, other structure all with figure identical.
Claims (2)
1. an eccentric cam running shaft bearing sleeve, it is characterized in that, the external diameter of camshaft bearing sleeve is by two sections of different center lines, and cylindrical body forms, the endoporus of its bevel gear wheel match position and lower end section, with the endoporus of the straight lining center line at the position distance that mutually staggers that is slidably matched.
2. eccentric cam running shaft bearing sleeve according to claim 1, is characterized in that: the external diameter of camshaft bearing sleeve is made up of the cylindrical body of two sections of different center lines.
