Specific embodiment

The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.

As shown in Figure 1, a kind of pre-installation bearing being readily transported, including needle bearing 1, pre-install the structure composition of bearing Part are as follows: including asessory shaft 2, asessory shaft 2 is passed through from the inner ring of needle bearing 1, and right baffle-plate 3A and right gear are arranged on asessory shaft 2 Plate 3B, needle bearing 1 is between right baffle-plate 3A and right shell body 3B, the outside of right baffle-plate 3A and right shell body 3B on asessory shaft 2 Outside is respectively arranged with nylon jacket 5, and nylon jacket 5 and asessory shaft 2 are interference fitted, in order to limit the outside movement of baffle.

In order to facilitate the disassembly of baffle, so baffle includes the first halfround bar slice 31 and the second halfround bar slice 32 again；

The structure of first halfround bar slice 31 are as follows: the inner side edge upper surface of the first halfround bar slice 31 offers the first keyway 33, and first The inner side edge lower surface of halfround bar slice 31 is fixedly installed the first pin key 34；

The structure of second halfround bar slice 32 are as follows: the inner side edge upper surface of the second halfround bar slice 32 offers the second pin key 37, and second The inner side edge lower surface of halfround bar slice 32 is fixedly installed the second keyway 38；

It allows the first halfround bar slice 31 and the second halfround bar slice 32 by mating connection between pin key and cotter way, thus facilitates Baffle dismantle.

Be respectively formed chamfering 35 in the inner side edge upper corners of halfround bar slice and inner side edge lower end angle, such first halfround bar slice 31 with The connection of second halfround bar slice 32 just makes to form V-shaped part between 2 chamferings 35, we can tear baffle open from V-shaped part It unloads, it is more convenient, fast.

The first halfround bar slice 31 or the second halfround bar slice 32 are fallen into mechanical equipment during dismantling baffle in order to prevent, it is difficult to Take out, so be provided with connecting rope 36 between the first halfround bar slice 31 and the second halfround bar slice 32,36 one end free end of connecting rope with The outer semicircle side of first halfround bar slice 31 is fixedly connected, the outer semicircle of the other end free end of connecting rope 36 and the second halfround bar slice 32 Side is fixedly connected, and first halfround bar slice 31 and the second halfround bar slice 32 can be taken from mechanical equipment together by connecting rope 36 Out.

Nylon jacket 5 easy to dismantle is convenient for nylon jacket 5 from asessory shaft 2 so offering the 5A that cracks in nylon jacket 5 It is radial to dial from and then reducing the time used in each component on disassembly pre-installation bearing.

In order to being lubricated and can be opened on surface of the baffle inner side edge with 1 contact aside of needle bearing in needle bearing 1 Equipped with mounting groove, and then oiling cotton 4 is placed in mounting groove so as to being lubricated inside needle bearing 1, in order to better Playing dustproof effect should allow oiling cotton 4 and outer side edges, inner side edge and the needle roller side of needle bearing 1 to fit closely.

Specific operation process is as follows, and asessory shaft 2 is first passed through 1 inner ring of needle bearing, is arranged with right baffle-plate on asessory shaft 2 3A and right shell body 3B, needle bearing 1 between right baffle-plate 3A and right shell body 3B, right baffle-plate 3A and right shell body 3B respectively with needle roller axis It holds 1 two sides to fit closely, be offered on the surface that right baffle-plate 3A and right shell body 3B are contacted with 1 two sides of needle bearing respectively Then mounting groove is provided with the nylon for the 5A that cracks to place oiling cotton 4 on the outside of the outside of right baffle-plate 3A and right shell body 3B Set 5, nylon jacket 5 are interference fitted with asessory shaft 2.

The pre-installation bearing that the utility model is readily transported can prevent needle roller in carrying and transportational process from bearing It falls off, to reduce in the damage carried with generated in transportational process, moreover it is possible to act on and prevent to being lubricated inside needle bearing 1 Dirt prevents needle roller from getting rusty, convenient for the installation in mechanical equipment, all parts easy to disassemble pre-installed in bearing, significantly Improve installation effectiveness, ensure that the utilization rate of needle bearing 1.

It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims Property range.
