Abstract
The utility model relates to a spherical roller bearing with an eccentric bushing and a wide inner ring, which comprises an inner ring, an outer ring, a retainer and two rows of rolling bodies, and ischaracterized in that the inner ring is of a wide inner ring, wherein one end of the inner ring is provided with an eccentric bushing, the eccentric bushing is provided with at least one pin hole anda screw hole, the eccentric busing is fixedly connected with the inner ring, the outer ring is sleeved on the middle part of the inner ring, the two columns of rolling bodies are respectively arranged between the inner and the outer rings to form a raceway and are locked and limited by the retainer, and a middle spacing ring is arranged between the two columns of rolling bodies. The spherical roller bearing has scientific, reasonable and creative design, strong economic adaptability, stability and reliability, solves the running problem that two shafts are not concentric to each other on thewood processing machine, and has promising development prospect. The spherical roller bearing is applicable to the wood processing machines.
Description
Technical field
The utility model relates to a kind of bearing, and concrete is the selfaligning roller bearing that has the wide inner ring of eccentric bushing.
Background technique
Bearing is all used on some equipment of all trades and professions and utensil widely, and at practical situations such as the structural feature of equipment, load that bearing is estimated carrying and Environmental Conditions, it is varied that the kind model of bearing also presents, complete.Selfaligning roller bearing just belongs to a series in the bearing, though comparatively general selfaligning roller bearing can bear radial load at present, but can only bear the less axial displacement that is limited in thrust load axle (shell) in the play limit, to have a greatly reduced quality and be installed on the optical axis that does not have shoulder self-aligning performance and radial capacity, mounting or dismounting simultaneously are also convenient inadequately, especially to wood processing machinery, the two ends of bearing are connecting two major axis respectively and are working simultaneously when usually using, this just requires bearing to have the function of aligning, both had the aligning structure, again can two ends connecting two major axis and working simultaneously, this common selfaligning roller bearing to present use is that bigger one of difficulty can inscribe.
This bearing is wearing and tearing extremely easily under for a long time load rotates, this means present use selfaligning roller bearing working life not length also be a defective of its existence.
Summary of the invention
The purpose of this utility model is to exist shortcoming and not enough in order to solve when present woodworking machinery special bearing is worked, and a kind of selfaligning roller bearing that has the wide inner ring of eccentric bushing is provided.
The technological scheme that adopts is:
The selfaligning roller bearing that has the wide inner ring of eccentric bushing, comprise inner ring, outer ring, retainer and two row rolling elements, its technological points is: inner ring is that an end of wide inner ring, inner ring is equiped with eccentric bushing, eccentric bushing is provided with at least one pin-and-hole and screw, eccentric bushing is fixedlyed connected with inner ring, and the outer ring is set in the middle part of inner ring, and two row rolling elements are installed in respectively in the raceway that forms between inner ring and the outer ring, and, between two row rolling elements, be provided with middle spacer ring by retainer locking and spacing.
The width of above-mentioned inner ring is greater than the width of outer ring.
Advantage of the present utility model is:
The selfaligning roller bearing that has the wide inner ring of eccentric bushing is installed in the close bearing support of envelope, owing to have wide inner ring, can connect two major axis and work simultaneously, good operating stability, the aligning effect is splendid, has improved working efficiency, energy efficient, and installation and removal are convenient in addition, avoid the damage of axle simultaneously.
The utility model design science, reasonable, original, economic serviceability is strong, reliable and stable, adequate solution the running problem during the diaxon decentraction on the wood processing machinery, have development prospect preferably.The utility model is applicable to that wood processing machinery uses.
Description of drawings
Fig. 1 is an a kind of embodiment's of the present utility model structural representation.
Embodiment
