Abstract
The utility model relates to an oiling structure, in particular to an oiling structure of a pressing wheel bearing, which can fill grease directly towards the bearing through a pipeline inside a pressing wheel shaft. The oiling structure of the pressing wheel bearing comprises the pressing wheel shaft, a bearing sleeved on the pressing wheel shaft and a protective cover which is arranged on two sides of the bearing and sleeved on the pressing wheel shaft. A grease pipeline two is arranged in the centers of two ends of the pressing wheel shaft along the center line direction. A grease pipeline one communicated with the grease pipeline two is arranged at the position of the pressing wheel shaft where the protective cover is sleeved. The oiling structure of the pressing wheel bearing has the advantages of being convenient to fill grease and easy to disassemble, and improving service life of the bearing.
Description
Technical field
The utility model relates to a kind of oil injection structure, is specifically related to a kind of pinch roller bearing oil injection structure that directly injects butter by the pipeline in the wheel pressing shaft to bearing.
Background technique
The pelleter pressing wheel device is the critical piece of this machine, and the quality of pinch roller bearing seal is very crucial.The quality and the output that are related to main frame.Because the pinch roller per minute rotates the hundreds of circle, temperature is up to nearly Baidu, and the feed dust is all-pervasive, and environment is very abominable in the machine.Now the most of producers of the machine on the market adopt prevent dust two end caps on both sides of stuffing box bearing, and three screws are reinforced, and it is very difficult to think to add butter again during work, in case screw becomes flexible, dust creeps into bearing chamber, and bearing will be stuck.
Summary of the invention
The utility model purpose is to overcome deficiency of the prior art and provides a kind of oiling convenient, can improve the pinch roller bearing oil injection structure of bearing life.
The purpose of this utility model is achieved in that a kind of pinch roller bearing oil injection structure; comprise wheel pressing shaft, be sleeved on bearing on the wheel pressing shaft, be arranged on the bearing both sides and be sleeved on protective cover on the wheel pressing shaft; the center portion at described wheel pressing shaft two ends is provided with butter pipeline two along centerline direction, and the position of suit protective cover is provided with the butter pipeline one that is communicated with this butter pipeline two on wheel pressing shaft.
Between bearing and protective cover, be provided with oil sealing.
The utlity model has following advantage: the utlity model has the filling butter conveniently, dismounting is simple, improves the advantage of bearing life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1; the utility model comprises wheel pressing shaft 1, be sleeved on bearing 2 on the wheel pressing shaft 1, be arranged on bearing 2 both sides and be sleeved on protective cover 4 on the wheel pressing shaft 1; the center portion at described wheel pressing shaft 1 two ends is provided with butter pipeline 27 along centerline direction, and the position of suit protective cover 4 is provided with the butter pipeline 1 that is communicated with this butter pipeline 27 on wheel pressing shaft 1.
Between bearing 2 and protective cover 4, be provided with oil sealing 3.
To achieve these goals, the utility model adopts following technological scheme.Be drilled with butter pipeline 27 at center, wheel pressing shaft 1 two ends, and add grease nipple at the two-end part of butter pipeline 27, grease gun aligning grease nipple gets final product during oiling.The position of suit protective cover 4 is drilled with the butter pipeline 1 that is communicated with butter pipeline 27 on wheel pressing shaft 1, and butter directly enters in the bearing chamber by butter pipeline 27, butter pipeline 1 like this.Near bearing 2 two ends two oil sealings 3 are installed respectively, both sides, oil sealing 3 place respectively are equipped with metal coating lid 4, and 4 outsides are covered in metal coating card 5 in the pinch roller, block 5 in pinch roller, the outer cover of protective cover 4, oil sealing 3, bearing 2 is equipped with pinch roller 8, forms a complete structure like this.
