Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1: an inner ring lengthened deep groove ball bearing is shown in figure 1 and comprises a bearing inner ring 1, a bearing outer ring 2, steel balls 3, a retainer 4 and a dust cover 5. The axial center of the outer side surface of the bearing outer ring 2 is provided with a circle of connecting groove 15 for connecting a rubber sleeve. The steel balls 3 are clamped between the bearing outer ring 2 and the bearing inner ring 1 and are circumferentially and uniformly distributed in a limiting manner through the retainer 4. The edge at 2 axial both ends of bearing inner race has joint interface 18, and shield 5 includes lid 19, and the outward flange of lid 19 is provided with the joint turn-ups 20 that the joint interface 18 was gone into to the card, and the inward flange of lid 19 has the interior edge 21 of supporting of perpendicular to lid 19, supports earlier in along 21 and bearing inner race 1 after supporting, through to the application of force of joint turn-ups 20, makes the deformation of lid 19, along the card joint interface 18 that goes into.
As shown in fig. 1 to 4, a circle of oil storage tank 6 is disposed at the center of the bearing inner ring 1 along the axial length, a mounting groove 7 for rolling and mounting the steel balls 3 is disposed on the inner wall of the bearing inner ring 1, an oil outlet 8 is disposed at the bottom of the oil storage tank 6 facing the mounting groove 7, and an oil filling hole 9 facing the oil storage tank 6 along the axial direction of the bearing is disposed at the bearing inner ring 1. An oil outlet sponge 16 is bonded at the oil outlet 8, and the oil outlet sponge 16 is directly contacted with the steel ball. The seal groove 11 of symmetry is seted up to oil filler point 9 one end outwards, seal groove 11 includes along 9 axial entering sections 12 of oil filler point and wavy linkage segment 13, 11 departments of seal groove are connected with the ferromagnetic sealing plug 10 to the shutoff of oil filler point 9, the both ends an organic whole of sealing plug 10 is provided with the connecting rod 22 the same with the 11 width in seal groove, connecting rod 22 rotates after entering section 12 entering, it is stable at wave section department, need just can change sealing plug 10 out through the instrument.
