Abstract
The utility model relates to a ball bearing nylon holding frame structure with a reinforcing rib, comprising a ball bearing nylon holding frame, a holding pawl, a ball bag, and a ball bag lock, characterized in that the ball bag lock opening is provided with a cylindrical surface, an oil groove is provided at the bottom of the ball bag, and a reinforcing rib is provided at the back of the holding pawl. Deformation of the holding frame is reduced, lubrication effect of the contact surface between the steel ball and the holding frame is improved, and poor bearing flexibility caused by the holding frame is greatly improved. In 6210 cases of the utility model during practical using, Ball damage rate of the steel ball caused by the holding frame is reduced by over 20%, and the poor flexibility rate caused by the holding frame is reduced by over 50%.
Description
Technical field
The utility model relates to a kind of ball bearing nylon cages, particularly a kind of ball bearing nylon cages structure with stiffening rib.
Background technique
The bearing nylon cages structure of normal configuration is shown in figure one at present.Retainer ball pocket 2 adopts the shaping of proper circle ball, and ball pocket fore shaft 1 adopts the tangent plane structure, and when the bearing assembling press-fited nylon cages, the fore shaft tangent plane of retainer easily made steel ball surface scratch, and then influences the bearing vibration noise; Simultaneously, because the nylon cages easy deformation adopts ball pocket grease when bearing working of proper circle ball shaping to be difficult for entering inside, ball pocket hole, cause that easily the bearing flexibility of revolution is bad.
Summary of the invention:
The purpose of this utility model is ball pocket and the existing the problems referred to above of ball pocket fore shaft that solve prior art middle (center) bearing nylon cages, and a kind of ball bearing nylon cages structure with stiffening rib is provided.A kind of ball bearing nylon cages structure of the utility model design with stiffening rib, comprise ball bearing nylon cages, holding claw, ball pocket, ball pocket fore shaft, it is characterized in that: ball pocket fore shaft is the cylndrical surface, offers an oil groove in the bottom of ball pocket, is provided with a stiffening rib at the back side of holding claw.The utility model has the advantages that the distortion that has reduced retainer, improved the lubrication effect of steel ball and retainer surface of contact again, it is bad to reduce the bearing flexibility that retainer causes greatly.Show that through actual the use 6201 being example, this structure can reduce retainer to the ball rate of hindering of steel ball more than 20%, reduce the flexibility reject ratio that retainer causes and reach more than 50%.
Description of drawings:
Fig. 1 is the bearing nylon cages structural representation of prior art,
Fig. 2 is the ball bearing nylon cages structural representation of band stiffening rib of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment:
Comprise ball bearing nylon cages 1, holding claw 2, ball pocket 3, ball pocket fore shaft 4, it is characterized in that: ball pocket fore shaft 4 is the cylndrical surface, offers an oil groove 5 in the bottom of ball pocket 3, is provided with a stiffening rib 6 at the back side of holding claw 2.Because this new structure is modified into cylindrical surface structure at ball bearing nylon cages 1 ball pocket fore shaft 4 places, when bearing press mounting ball bearing nylon cages 1, steel ball is in the cylndrical surface of ball pocket fore shaft 4 falls into the ball pocket 3 of ball bearing nylon cages 1, and so ball bearing nylon cages 1 just is not easy steel ball is scratched.Simultaneously, increased a stiffening rib 6 at the back of holding claw 2, bottom in ball pocket 3 holes increases an oil groove 5, like this, both increased the intensity of ball bearing nylon cages 1 holding claw 2, and can make ball bearing nylon cages 1 ball pocket 3 store grease again, in bearing working, both reduced the distortion of ball bearing nylon cages 1, and improved the lubrication effect of steel ball and ball bearing nylon cages 1 surface of contact again, it is bad to reduce the bearing flexibility that ball bearing nylon cages 1 causes greatly.Show that through actual the use 6201 being example, this structure can reduce retainer to the ball rate of hindering of steel ball more than 20%, reduce the flexibility reject ratio that ball bearing nylon cages 1 causes and reach more than 50%.
Claims (1)
1. ball bearing nylon cages structure with stiffening rib, comprise ball bearing nylon cages, holding claw, ball pocket, ball pocket fore shaft, it is characterized in that: ball pocket fore shaft is the cylndrical surface, offers an oil groove in the bottom of ball pocket, is provided with a stiffening rib at the back side of holding claw.
