Abstract
The utility model provides a press mounting head of external sealing element of supporting roller bearing, which is characterized in that: the shape of the main body is cylindrical. A through hole along axial line of a circular axis is divided into two sections, wherein diameter of a thicker section is the same with the outer diameter of an external sealing element exposed at the end surface of a bearing seat, and diameter of a thinner section is the same as that of the supporting roller shaft. The utility model makes the press mounting of external sealing element of bearing in two-piece laminated type bearing sealing element in place. Moreover, the sealing element is not easy to be damaged.
Description
The utility model belongs to a kind of installation Idler bearing seal compaction tool, is a kind of Idler bearing outside seal may press-loading head specifically.
At present, the Idler bearing seal is generally the integral structure that has metal, installs to compress the used press-loading head of seal only for a kind of.And new 207 profile shafts that adopt to hold seal be two-piece-dress laminated type plastic seal, existing press-loading head structure can't be press-fit into place inside and outside plastic seal.
The purpose of this utility model is to provide a kind of Idler bearing outside seal may press-loading head at the deficiencies in the prior art, can exactly the bearing outside seal may in the two-piece-dress laminated type bearing seal be press-fit into place, and, be difficult for making the seal breakage.
The purpose of this utility model is achieved by the following technical solution: a kind of Idler bearing outside seal may press-loading head, it is characterized in that body shape is cylindric, circular shaft through hole along its axis is divided into two sections that join, thicker one section diameter is identical with the outside diameter that outside seal may is exposed the bearing block end face, and thinner one section diameter is identical with the roller carrier shaft diameter.
Described thicker one section circular shaft through hole length is identical with the height that outside seal may is exposed the bearing block end face.
The utility model compared with prior art has many advantages and good effect:
1, the body shape of the utility model press-loading head is cylindric, circular shaft through hole along its axis is divided into two sections that join, thicker one section circular shaft through-hole diameter is identical with the outside diameter that outside seal may is exposed the bearing block end face, and thinner one section diameter is identical with the roller carrier shaft diameter.Thinner one section circular shaft through hole can insert roller carrier shaft one end, and thicker one section circular shaft through hole inner face and circle side thereof can compress the outside seal may that is enclosed within on the roller carrier shaft easily.
2, thicker one section circular shaft through hole length of the utility model press-loading head and the outside seal may height that exposes the bearing block end face is identical.Make to press-fit accurately to put in place, and, be difficult for making the seal breakage.
3, it is simple in structure, and processing and fabricating is convenient, uses reliable.
Fig. 1 is the utility model press-loading head user mode schematic diagram.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to Fig. 1, a kind of Idler bearing outside seal may press-loading head, its body shape is cylindric, circular shaft through hole along its axis is divided into two sections that join, thicker one section circular shaft through-hole diameter is identical with the outside diameter that outside seal may (4) is exposed bearing block (2) end face, thicker one section circular shaft through hole length is identical with the height that outside seal may (4) is exposed bearing block (2) end face, and thinner one section circular shaft through hole is identical with roller carrier shaft (6) diameter.During use, with inner seal liner press-loading head (7) inner seal liner (3) is press-fited earlier.Again outside seal may (4) and outside seal may press-loading head (5) are enclosed within on the roller carrier shaft (6), oil cylinder push rod (8) inserts and pushes ahead from inner seal liner press-loading head (7) one ends, inner seal liner press-loading head (7) front end face withstands on outside seal may press-loading head (5) rear end face, rely on thicker one section circular shaft through hole inner face of outside seal may press-loading head (5) and circle side thereof easily 207 plastic outside seal may (4) front ends that are enclosed within on the roller carrier shaft (6) to be pressed on bearing (1) end face, and make inside and outside seal (3,4) keep certain interval, it is smooth to guarantee that carrying roller rotates.
Claims (2)
1, a kind of Idler bearing outside seal may press-loading head, it is characterized in that body shape is cylindric, circular shaft through hole along its axis is divided into two sections that join, thicker one section diameter is identical with the outside diameter that outside seal may (4) is exposed bearing block (2) end face, and thinner one section diameter is identical with roller carrier shaft (6) diameter.
2,, it is characterized in that the height that described thicker one section circular shaft through hole length and outside seal may (4) expose bearing block (3) end face is identical according to the described Idler bearing outside seal may of claim 1 press-loading head.
