Abstract
The invention relates to a bearing used grease filling device, which includes a fixation pipe and a filling head that are connected fixedly, wherein a grease hole is arranged in the fixation pipe and the filling head, a plurality of circles of filling holes are arranged on the filling head and are communicated with the grease hole. The bearing used grease filling device is characterized by further including O-shaped seal rings, one groove is arranged on the filling head at each of the two ends outside the filling holes, and one O-shaped seal ring is arranged in each groove. The bearing used grease filling device has the advantages of evenly greasing a bearing and reducing grease waste.
Description
Technical field
The present invention relates to a kind of oil addition device, relate in particular to a kind of bearing and use the oil addition device.
Background technique
Present bearing comprises fixed block and filling head with the oil addition device, and fixed block is fixedly connected with filling head, in fixed block and filling head, is provided with grease holes, on filling head, is provided with some circle filler ports, and filler port and grease holes communicate; Bearing is during with the oil addition device busy; Earlier bearing housing is contained on the filling head; Grease is injected in the bearing through grease holes and filler port; When normal oil addition pressure grease easily the gap location from the needle roller Surface runoff to the needle roller two ends pile up, grease can penetrate from the bearing two ends when big when oil addition pressure is transferred, and influences the operating personnel and wastes 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; Pile up from the needle roller Surface runoff to the needle roller two ends when the grease-adder pressure gauge occurs grease again during in normal range (NR) easily, and when bearing is added grease, bearing can be inconjunction with the surplus grease that filler port is emerged when filling head is extracted, it is inhomogeneous to form the bearing bore diameter grease easily.
Summary of the invention
To above-mentioned shortcoming, the object of the present invention is to provide and a kind ofly can carry out even stuffing to bearing and use the oil addition device with the bearing that reduces the grease waste.
Technology contents of the present invention is: a kind of bearing is used the oil addition device; Comprise fixed block and filling head, fixed block is fixedly connected with filling head, in fixed block and filling head, is provided with grease holes; On filling head, be provided with some circle filler ports, 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 present invention is compared with prior art had is: through on the filling head at two ends, the grease holes outside, respectively being provided with a groove; In groove, be placed with an O RunddichtringO; Can prevent that thus grease from getting 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 through 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 in the stuffing process, when the surperficial grease packing phenomenon of needle roller occurring, can extract filling head through bearing.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Further narrate the present invention below in conjunction with embodiment and accompanying drawing thereof.
As shown in Figure 1, a kind of bearing is used the oil addition device, comprises fixed block 1 and filling head 2; Fixed block 1 is fixedly connected with filling head 2; In fixed block 1 and filling head 2, be provided with grease holes 3, on filling head 2, be provided with some circle filler ports 2.1, filler port 2.1 communicates with grease holes 3; 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 invention does, earlier bearing 5 is sleeved on the filling head 2, and grease is injected in the bearing 5 through grease holes 2 and filler port 2.1.
