Abstract
A bearing roller shaft convenient for quickly disassembling a bearing in a vinegar sheet finished product washer is characterized in that an oil filling hole leading to a bearing installation part is drilled at one end of the bearing roller shaft, one end of the oil filling hole is arranged on the end face of the bearing roller shaft, and the other end of the oil filling hole is arranged on the excircle of the bearing installation part on the bearing roller shaft. The diameter of the oil filling hole is 10 mm. And an oil injection nozzle is arranged at one end of the oil injection hole on the end surface of the carrier roller shaft. And continuously filling lubricating grease into the oil filling hole to form an oil film between the inner diameter of the bearing and the outer diameter of the support mixing shaft, and separating the bearing from the support mixing shaft along with the increase of oil pressure. The utility model discloses set up the oil filler point between the tip of bearing roller axle and bearing installation position, utilize the lubrication characteristic of lubricating grease, form the one deck oil film between bearing internal diameter and support mixed axle external diameter, through lasting filling lubricating grease, the oil pressure increase makes the two easy separation of bearing and bearing roller axle come, has reduced the maintenance degree of difficulty, and convenient the dismantlement has avoided the violence to dismantle.
Description
Technical Field
The utility model relates to a bearing roller axle that is arranged in vinegar piece finished product scrubber to be convenient for dismantle large-scale bearing on it fast to the realization belongs to bearing installation bearing roller axle technical field to transformation, maintenance and the maintenance of scrubber.
Background
In the production of cellulose acetate, there are two washers in the finished acetate flake area, called washer A and washer B, respectively, and the direction of the washing water is opposite to the main flow of the cellulose acetate flake. The diameter of the washer is DN2700mm, the length of the washer is 12800mm, 24 cells are arranged in the washer, and each cell is internally provided with a screen. The vinegar pieces are washed by water in each cell in sequence, the whole washer rotates at the speed of 1.2 revolutions per minute, and the carrier roller shafts are important supports for maintaining the normal rotation of the washer and are positioned at the middle part and the lower part of the washer.
The washer bearing roller shaft is matched with a bearing with the model of 22320, the inner diameter of 100mm, the outer diameter of 215mm, the width of 73mm and the weight of 13KG, the shaft diameter of the bearing roller shaft is cun phi 100mm, the bearing roller shaft and the bearing form interference fit, no gap exists between the shaft outer diameter of the bearing roller shaft and the inner diameter of the bearing, the bearing roller shaft is tightly and fixedly connected, and the bearing roller shaft cannot rotate independently.
The existing problems are that when the washer works normally, the carrier roller shaft and the bearing are taken as a whole, the carrier roller shaft and the bearing bear load together, the bearing is easy to wear and break down, the bearing needs to be overhauled on site by maintainers, various dismounting devices cannot be used during dismounting and inspection due to the position of the bearing, the original carrier roller shaft bearing is difficult to dismount and particularly difficult to dismount, the maintainers cannot deeply inspect whether the bearing is damaged or not, the equipment fault cannot be eliminated, and the bearing sometimes can be dismounted violently, so that the labor is wasted and the safety is not ensured.
SUMMERY OF THE UTILITY MODEL
The utility model discloses dismantle the problem of difficulty to the large-scale bearing among the vinegar piece finished product scrubber that cellulose acetate production process used, provide a simple structure, can dismantle the bearing in the vinegar piece finished product scrubber of bearing fast convenient to dismantle the bearing's bearing roller axle fast.
The utility model discloses a bearing roller axle convenient to dismantle bearing fast in vinegar piece product washing ware adopts following technical scheme:
one end of the carrier roller shaft is drilled with an oil filling hole leading to the bearing mounting part, one end of the oil filling hole is arranged on the end surface of the carrier roller shaft, and the other end of the oil filling hole is arranged on the excircle of the bearing mounting part on the carrier roller shaft.
The diameter of the oil filling hole is 10 mm.
And an oil injection nozzle is arranged at one end of the oil injection hole on the end surface of the carrier roller shaft.
And continuously filling lubricating grease into the oil filling hole to form an oil film between the inner diameter of the bearing and the outer diameter of the support mixing shaft, and separating the bearing from the support mixing shaft along with the increase of oil pressure.
The utility model discloses set up the oil filler point between the tip of bearing roller axle and bearing installation position, utilize the lubrication characteristic of lubricating grease, form the one deck oil film between bearing internal diameter and support mixed axle external diameter, through lasting filling lubricating grease, the oil pressure increase makes the two easy separation of bearing and bearing roller axle come, has reduced the maintenance degree of difficulty, and convenient the dismantlement has avoided the violence to dismantle.
Drawings
Fig. 1 is a schematic structural view of the carrier roller shaft of the present invention.
In the figure: 1. a roller carrier shaft, 2 an oil filling hole and 3 a bearing mounting part.
Detailed Description
The utility model provides a bearing roller shaft of large-scale bearing in vinegar piece finished product scrubber, the epaxial bearing of bearing roller is dismantled fast to the convenient to, whether the inspection bearing damages.
As shown in FIG. 1, an oil hole 2 is formed at an end portion of a carrier roller shaft 1, and the diameter of the oil hole 2 is 10 mm. One end of the oil filling hole 2 is arranged on the left end face of the carrier roller shaft 1, and the other end of the oil filling hole is arranged on the excircle of the bearing installation part 3 of the carrier roller shaft 1, namely, the oil filling hole is arranged between the carrier roller shaft 1 and a bearing, so that the excircle of the carrier roller shaft at the bearing installation part 3 is communicated with the outside. The oil filler hole 2 can be an axial straight hole and a radial straight hole which are communicated with each other, as shown in figure 1. Or may be a slanted hole. The oil filling hole 2 can be provided with an oil filling nozzle.
Lubricating grease is continuously filled into the oil filling hole 2 through the oil filling nozzle, a layer of oil film is formed between the inner ring of the bearing and the outer circle of the supporting and mixing shaft 1, a gap is formed between the outer circle of the supporting and mixing shaft 1 and the inner diameter of the bearing along with the increase of oil pressure to 0.3-0.8MPa, and then the bearing is rotated, so that the bearing and the supporting and mixing shaft are easily separated.
The method forms an oil film by continuously filling lubricating grease, separates the bearing from the roller carrier shaft 1 by a simple method, realizes the quick and simple disassembly of the bearing, and solves the problem in the field of the disassembly of large bearings in washers.
