Description
Technical field
The utility model belongs to technical field of bearings, more particularly to a kind of novel cylinder roller bearing.
Background technique
Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is to support mechanical rotary body, is reduced
Coefficient of friction in its motion process, and guarantee its rotating accuracy.Traditional ball bearing has the disadvantages thatRolling element and pipe
Road contact area is small；Impact resistance ability is poor, and radial internal clearance is bigger, causes vibration and noise larger；At a high speed, case of heavy load
Under, service life reduction.
Cylinder roller bearing feature: roller and raceway be line contact or repair it is offline contact, radial large carrying capacity is suitable for
Bear heavy load and impact load；Coefficient of friction is small, is suitble to high speed limit revolving speed close to deep groove ball bearing.Therefore cylindrical roller axis
It holds with wide application prospect.
Summary of the invention
The purpose of this utility model is to provide a kind of novel cylinder roller bearing, which uses cylindrical roller, solves
Traditional ball bearing impact resistance ability is poor, noise is big, the service life is short disadvantage has high use value.
Purpose of the utility model is realized as follows: a kind of novel cylinder roller bearing, including inner sleeve, housing, main circle
Housing is arranged in column rolling, the rolling of outside cylinder, inside cylindrical rolling, the outside of inner cover, and the inner sleeve, housing are disposed as annulus
Shape installs main cylinder rolling between the inner sleeve and housing, the both ends of the main cylinder rolling are set as spherical structure, described
The concave spherical surface structure mutually agreed with the spherical structure at main cylinder rolling both ends is respectively set in inner sleeve inner sidewall, housing inner sidewall；
Setting outside cylinder rolls between the main cylinder rolling and housing, and the outside cylinder rolling is spaced with the rolling of main cylinder
Setting, the outside cylinder roll tangent setting respectively between main cylinder rolling adjacent thereto, housing；
Setting inside cylindrical rolls between the main cylinder rolling and inner sleeve, and the inside cylindrical rolling is spaced with the rolling of main cylinder
Setting, the inside cylindrical roll tangent setting respectively between main cylinder rolling adjacent thereto, inner sleeve.
Two bottom surfaces of the axis direction of the main cylinder rolling perpendicular to inner sleeve.
The main cylinder rolls, outside cylinder rolls, the axis of inside cylindrical rolling is parallel to each other.
The both ends of the outside cylinder rolling are set as spherical structure, and the concave spherical surface structure with its corresponding position housing
Mutually agree with.
The both ends of the inside cylindrical rolling are set as spherical structure, and the concave spherical surface structure with its corresponding position inner sleeve
Mutually agree with.
The beneficial effect that the utility model generates is: first is that, the utility model uses cylindrical roller, compared to traditional ball axis
The ball-type roller held increases rolling element and inner sleeve, the contact area of outer inner room, hence it is evident that enhance the receiving of bearing radial load
Ability；The vibration and noise generated when in addition, bearing working can also be reduced using cylindrical roller.Second is that the utility model is arranged
Outside cylinder rolling, inside cylindrical rolling separate every two adjacent main cylinder rolling, avoid main cylinder roll between phase mutual friction, rise
To the function of the retainer of traditional ball bearing, to further enhance the service life of the utility model.Third is that the utility model
The rolling of main cylinder, the rolling of outside cylinder, inside cylindrical rolling both ends be respectively set to spherical structure, and inner sleeve, housing are pacified accordingly
The concave spherical surface structure mutually agreed with is set at holding position, the frictional force of bearing in use can be further decreased, improves axis
The service life held.
