Self-aligning bearing

Abstract

The invention discloses a self-aligning bearing, which comprises an outer spherical bearing, wherein a fixing ring is arranged at the outer side of the outer ring of the outer spherical bearing; the inner surface of the fixing ring is set to be a spherical surface completely matched with the outer surface of the outer ring; two processing grooves are symmetrically formed at one end surface of the fixing ring; the diameter of each processing groove is greater than the greatest diameter of the outer ring; the width of each processing groove is greater than the thickness of the outer spherical bearing; the depth of each processing groove is greater than 1 / 2 of the thickness of the outer spherical bearing. The self-aligning angle of the self-aligning bearing can reach 3 DEG; not only is the relatively self-aligning angle provided, and also a sealing ring can be arranged.

Description

technical field [0001] The invention relates to a bearing, more specifically to a self-aligning bearing. Background technique [0002] The outer spherical bearing is already a very mature industrial standard product. In the printing and packaging industry, adjustable guide rollers, compensation rollers, embossing rubber rollers, cooling rollers, etc. need to use self-aligning bearings, but the existing outer spherical self-aligning bearings Among them, the self-aligning ball bearing without sealing ring allows the self-aligning angle of 2.5°~3°, while the self-aligning bearing with sealing ring allows the self-aligning angle of 0.5°~1.5°. The center bearing cannot be equipped with a sealing ring, so the grease cannot be stored inside the bearing, and often in some structures where it is inconvenient to add grease to the bearing, the bearing is often in long-term operation without lubrication, so the bearing is easy to be worn. In turn, it will affect the flexibility of the ...

In turn, it will affect the flexibility of the roller, thereby affecting the printing quality, and in severe cases, it will cause equipment failure
