Abstract
The utility model relates to a grease filling device for a bearing. The grease filling device for the bearing comprises a fixing piece and filling heads, the fixing piece is fixedly connected with the filling heads, grease holes are arranged in the fixing piece and the filling heads, a plurality of circles of filling holes are arranged on the filling heads, and the filling holes are communicated with the grease holes; and the grease filling device for the bearing is characterized by further comprising O-shaped sealing rings, grooves are respectively arranged on the filling heads at two ends of the outer side of the filling holes, and the O-shaped sealing rings are arranged in the grooves. The grease filling device for the bearing has the advantages of evenly filling grease to the bearing and reducing waste of the grease.
Description
Technical field
The utility model relates to a kind of grease filling device, relates in particular to a kind of bearing grease filling device.
Background technique
Present bearing comprises fixed block and filling head with grease filling device, and fixed block is fixedly connected with filling head, is provided with grease holes in fixed block and filling head, is provided with some circle filler ports at filling head, and filler port and grease holes communicate; Bearing uses grease filling device when work, first bearing housing is contained on the filling head, grease is injected in the bearing by grease holes and filler port, grease easily flow to the gap location accumulation at needle roller two ends from the needle roller surface when normal oil addition pressure, grease can penetrate from the bearing two ends when oil addition pressure tunes up, affect the operating personnel and waste a large amount of greases, grease can not well lubricate on the needle roller surface or raceway of bearing when oil addition pressure is turned down, flow to the needle roller two ends from the needle roller surface and pile up when grease easily appears again during in normal range (NR) in the grease-adder pressure gauge, and the surplus grease that filler port can be emerged when when bearing is added grease bearing being extracted from filling head is inconjunction with, and easily forms the bearing bore diameter grease inhomogeneous.
Summary of the invention
For above-mentioned shortcoming, the purpose of this utility model is to provide a kind of and can carries out even stuffing and reduce the bearing grease filling device that grease is wasted bearing.
Technology contents of the present utility model is: a kind of bearing grease filling device, comprise fixed block and filling head, fixed block is fixedly connected with filling head, is provided with grease holes in fixed block and filling head, be provided with some circle filler ports at filling head, filler port and grease holes communicate; It is characterized in that it also comprises the O RunddichtringO, on the filling head at two ends, the filler port outside, respectively be provided with a groove, in groove, be placed with an O RunddichtringO.
The advantage that the utility model compared with prior art has is: by respectively be provided with a groove on the filling head at two ends, the grease holes outside, in groove, be placed with an O RunddichtringO, can prevent that thus grease from entering in the both ends of the surface clearance space from the needle roller surface, thereby reduced the unnecessary waste of grease, the phenomenon that can avoid grease to emerge toward both ends of the surface by elasticity O type circle, grease is more effective to be added on needle roller surface and the bearing race thereby make, and can play the effect of sparing fat by the O seal ring when can extract filling head by bearing when the surperficial grease packing phenomenon of needle roller occurring in the stuffing process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Further narrate the utility model below in conjunction with embodiment and accompanying drawing thereof.
As shown in Figure 1, a kind of bearing grease filling device comprises fixed block 1 and filling head 2, fixed block 1 is fixedly connected with filling head 2, be provided with grease holes 3 in fixed block 1 and filling head 2, be provided with some circle filler ports 2.1 at filling head 2, filler port 2.1 and grease holes 3 communicate; It is characterized in that it also comprises O RunddichtringO 4, on the filling head 2 at two ends, filler port 2.1 outside, respectively be provided with a groove 2.2, in groove 2.2, be placed with an O RunddichtringO 4.
Working principle of the present utility model is, first bearing 5 is sleeved on the filling head 2, and grease is injected in the bearing 5 by grease holes 2 and filler port 2.1.
