Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in Figs. 1-2, attached drawing is traditional roller, includes roller 1, swivel bearing 2, bearing block 3, inner end cap 4, outer
A swivel bearing 2 is installed at end cap 5 and transmission gear 7,1 spindle nose both ends of roller respectively, and swivel bearing 2 is installed on the seat of bearing block 3
In hole, bearing block 3 is connected by connecting plate 6 with wallboard by 5 fixed lock of inner end cap 4 and outer end cap, bearing block 3,1 axis of roller
First end is equipped with transmission gear 7, drives roller 1 to rotate by the rotation of transmission gear 7, bearing block is equipped with oil on 3 end face
Mouth 8, lubricating grease are injected by oil nozzle 8 inside swivel bearing 2, and Bearing inner ball or roller is made to be lubricated, and reduce bearing
Abrasion.
This kind of mode is only applicable to low speed, discontinuous operating occasion.If roller 1 is in continuous 24 hours and high speed（400
Meter or more/minute）Under working order, this structure is just difficult to be competent at, and bearing easily causes fever, hair during running at high speed
It scalds, and heat is directly passed on bearing block 3, then pass to other parts again, lead to part dilatancy, influence part
Precision aggravates bearing burden to influence bearing service life
A kind of circulating water bearing block disclosed in the present application, is transformed on its original base, passes through recirculated water
