Abstract

An upright rib thrust self aligning roller bearing comprises a pedestal ring, shaft washer, a plurality of rollers, cage and a bush. The surroundings of the upper section of the pedestal ring is provided with a plurality of rollers; the upper end of the plurality of rollers is enclosed inside roller locating hole of the cage; the shaft washer is embedded in the inner loop of the cage; the ribs at he upper section of the shaft washer are arranged in a line; and the shaft washer is locked with the plurality of rollers through the bush. The utility model is reasonable in design, easy in manufacture, low in cost and less in maintenance work. The upright rib thrust self aligning roller bearing can effectively reduce the sliding friction of the bearing; and the bearing has a good lubricating effect so that the rotation of the bearing is much flexible; the loading weight is increased and the life span is longer with in increasing of 20 to 30 percent. The utility model is applicable in the industries of machinery, metallurgy, mine, petrochemical industry, shipping and submarine, water conservancy and electric power and processing and so on, in particular suitable in the complex burden circumstance of that the thrust load of the bearing is in charge and shifted from thrust load to radial load.

Description

Straight rib type self-aligning thrust roller bearing

Technical field

The utility model relates to a kind of bearing, and concrete is straight rib type self-aligning thrust roller bearing.

Background technique

Bearing is the general component of multiple machinery, and bearing is because of the difference of usage and load-carrying ability, and has diversified kind and specification.Self-aligning thrust roller bearing is exactly a kind of series product in the bearing class, the self-aligning thrust roller bearing that uses is to adopt the circular arc type rib structure on the rib of blowout patche at present, this structure is adding man-hour, the size of circular arc rib be difficult to guarantee its precision, and the circular arc rib is very big with the sliding friction of roller contacting point in using, i.e. the very big sliding friction of existence, lubricant oil is difficult to enter, thereby cause insufficient lubrication, very be easy to generate rib burn phenomenon, thereby bearing life is reduced.Simultaneously take into account the circular arc rib structure in processing and making process, the volume of roller just can only be done more a little bit smallerly, thereby the load nature just can not be too big.This also is the major defect that adopts circular arc type rib self-aligning thrust roller bearing at present.

Summary of the invention

The purpose of this utility model is for the circular arc type rib self-aligning thrust roller bearing that solves present use exists that lubricant oil is difficult for flowing to, insufficient lubrication, load are lower, the troublesome problem of bearing and defective, change the circular arc rib into straight rib and provide a kind of, thereby fully lubricated, the straight rib type self-aligning thrust roller bearing of increase bearing capacity.

The technological scheme that adopts is:

Straight rib type self-aligning thrust roller bearing comprises seat ring, blowout patche, a plurality of roller, retainer and lining, install a plurality of rollers around the described seat ring top, the upper end of a plurality of rollers is sleeved in the roller positioning hole of retainer, blowout patche blocks its structure outline with the bottom of roller all around by lining:

Described blowout patche is embedded in the interior ring of the retainer that roller is housed all around, and the rib above the blowout patche is not set to straight line type.

The principle explanation:

Straight rib type self-aligning thrust roller bearing is on the basis of the circular arc type rib self-aligning thrust roller bearing that uses at present, the transformation of the way of circular arc rib is straight rib, make rolling element and rib be a way of contact, thereby reduce the sliding friction of bearing, lubricant oil enters easily, guarantee to lubricate fully, avoid the generation of rib burn phenomenon.The volume that can add large roller simultaneously increases the bearing rated load, thus the working life of improving bearing.

The utility model is reasonable in design, processes, makes simply, and cheap, the regular maintenance amount is less; Straight rib type self-aligning thrust roller bearing effectively reduces the sliding friction of bearing, bearing lubrication is good, rotate more flexible, bearing load is bigger, life-span is longer, bearing life can improve 20～30%, is applicable to all trades and professions such as machinery, metallurgy, mine, oil, chemical industry, the manufacturing of boats and ships submarine, hydraulic and electric engineering, processing, is specially adapted to use based on the occasion of the combined stress of the axial load of axial load and radial load.Need to prove that under the prerequisite that does not change present principles, can also make some changes or distortion to the utility model, this belongs to protection domain of the present utility model equally.
