Abstract
The invention relates to a cylindrical thrust roller bearing with a novel combined cage, which is mounted on the large precision vertical lathe spindles and is mainly used in the lathe industry. The bearing comprises shaft washers, a roller, races, cage seats, a spring pin and a cage cover, wherein the roller is arranged in one cage seat; the cage cover is in interference fit with the other cage seat; the spring pin links the other cage seat and the cage cover; the roller, the cage seats, the spring pin and the cage cover form a roller assembly; the roller assembly, the shaft washers and the races form the bearing; and the cage seats and the cage cover are all made of brass. The invention has the following benefits: the cage cover is in interference fit with the other cage seat; linkage through the spring pin is adopted to replace screw welding, thus solving the problems of large deformation under heat in the original welding mode, insecure welding spots and complex machining process; and the quality and the production efficiency of the bearing are obviously improved and the service life of the bearing is also obviously prolonged.
Description
Technical field
The present invention relates to a kind of cylindrical roller thrust bearing that machine industry is installed on the novel combined cage on the large-scale precision vertical lathe spindle that is mainly used in.
Background technique
Be applied to one of the former employing of serial cylindrical roller thrust bearing that machine industry is installed on the large-scale precision vertical lathe spindle and keep stand and a retainer cover combined structure; keep stand and connecting of lid to adopt the screw-type welding; the defective of this structure is that bearing constantly clashes into the retainer lid because of roller in high speed rotating work; making the screw attachment place snap and cause through regular meeting comes off; cause bearing life to reduce; use feedback from the user; this kind damage type is the principal element that influences bearing life; therefore, improving composite cage connection form is to improve the effective measures of bearing life.
Summary of the invention
In order to solve the low problem of bearing life, the invention provides a kind of cylindrical roller thrust bearing of novel combined cage.
Technological scheme of the present invention is: the cylindrical roller thrust bearing of novel combined cage comprises blowout patche 1, roller 2, seat ring 3, keeps stand 4, spring pin 5 and retainer to cover 6.Roller 2 is contained in and keeps in the stand 4, retainer lid 6 and maintenance stand 4 interference fit, spring pin 5 will keep stand 4 and retainer lid 6 to connect, and roller 2, maintenance stand 4, spring pin 5 and retainer lid 6 consist of roller assembly, and roller assembly and blowout patche 1, seat ring 3 are formed bearing.
Wherein, keep stand 4 and retainer lid 6 all to select brass material for use.
The invention has the beneficial effects as follows: retainer lid and maintenance stand interference fit, adopt spring pin to connect and replace the screw-type welding, it is big to have solved former connecting mode temperature distortion, solder joint is not firm, the processing technology complicated problems, bearing quality and manufacturing efficiency obviously improve, and also obviously improve working life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. blowout patche, 2. roller, 3. seat ring 4. keeps stand, 5. spring pin, 6. retainer lid.
Embodiment
