Abstract
The invention discloses a one-way thrust ball bearing, which is suitable for a rotor II-type jetting machine for mining and has the characteristics of long service life, flexible rotation and great smoothness. The one-way thrust ball bearing comprises a seat washer, a shaft washer, a retaining rack and steel balls, wherein the retaining rack is arranged between the seat washer and the shaft washer, the steel balls are mounted in the retaining rack and respectively come into contact with the seat washer and the shaft washer; the one-way thrust ball bearing has the outer diameter of 340-420mm, the inner diameter of 280-360mm and the height less than 36mm; the number of the steel balls is 50-80; and the retaining rack is made of nylon material.
Description
Technical field
The present invention relates to a kind of bearing, relate in particular to a kind of single direction thrust ball bearing.
Background technique
Mining to the size requirement height, and requires the long service life of bearing with the single direction thrust ball bearing that uses on the rotor II type sprayer, to avoid changing continually bearing.In addition, can not reduce flexible, the smooth degree of its rotation for this large-sized bearing.
Summary of the invention
Technical problem to be solved by this invention provides a kind of single direction thrust ball bearing, and this bearing is applicable to mining rotor II type sprayer, and long service life is rotated flexible, smooth and easy.
The present invention includes seat ring, blowout patche, retainer and steel ball, described retainer is arranged between seat ring and the blowout patche, and steel ball is installed in the retainer and is in contact with one another with seat ring and blowout patche respectively, and the external diameter of described single direction thrust ball bearing is 340～420mm, internal diameter is 280～360mm, and height is less than 36mm; Described retainer is made by nylon material; Described steel ball is 50～80.
Single direction thrust ball bearing among the present invention is applicable to mining rotor II type sprayer, and it can guarantee the normal operation of machine.The retainer that nylon material is made is long service life not only, and the cost of material is low.50～80 steel balls can guarantee that this large-sized bearing rotates more flexible, smooth and easy.
Figure of description
Fig. 1 is the structural representation of single direction thrust ball bearing.
Embodiment
