Abstract
The utility model discloses a bearing puller device for a roller shaft. The bearing puller device for the roller shaft is used in a matching mode with the roller shaft and a bearing. An inner ring is arranged in the bearing, the puller device comprises two half cylindrical roller pullers, a pull rod, a swivel nut and a hold hoop, the two roller pullers wrap in a combined mode to form a hollow cylindrical roller sleeve, threads are arranged on the pull rod, the swivel nut is arranged on the pull rod in a sleeved mode and is arranged in the roller sleeve in a clamped mode, and the hold hoop is arranged outside the roller sleeve in a sleeved mode. One ends of the roller pullers are provided with a groove respectively, the two grooves are combined in a wrapping mode, then are matched with the inner ring of the bearing and are capable of enabling the inner ring of the bearing to be clamped, and the diameter of the pull rod is smaller than that of the inner ring of the bearing. The bearing puller device for the roller shaft is capable of enabling the bearing inner ring clamped on the roller shaft to be taken down smoothly, and the roller shaft will not be damaged.
Description
[technical field]
The utility model relates to a kind of roller shaft and draws the horse device with bearing.
[background technology]
Winding head is to spin key equipment before the chemical fibre industry, its basic structure: chuck and hold-down roller, form a classical coiler device; Roller be play in the textile machine feed to give, the cylindrical rotary part of effects such as drawing-off, output, be widely used in mechanisms such as drawing-off, combing, conveying.Be arranged with bearing on the roller shaft of winding head, bearing needs periodic replacement.In the process of changing bearing, often run into bearing ball and come off, making bearing inner race be stuck on the roller shaft can't take off smoothly.Generally speaking, can be again in bearing, add ball, take off bearing then, but very time-consuming, difficulty is big; Another kind of settling mode is that inner ring is ground off, but easily roller shaft is damaged.
[summary of the invention]
The technical problems to be solved in the utility model, be to provide a kind of roller shaft with bearing draw the horse device, can easily the bearing inner race that is stuck on the roller shaft be taken off smoothly, and not damage roller shaft.
The utility model is achieved in that
A kind of roller shaft draws the horse device with bearing, the described horse device that draws cooperates roller shaft and bearing to use, be provided with inner ring in the described bearing, the described horse device that draws comprises that two semi-cylindrical pressure rollers draw horse, a pull bar, a swivel nut and an anchor ear, described two pressure rollers draw horse to fill the span of a man's arms to form a hollow cylinder and draw the horse sleeve, and described pull bar is provided with screw thread, and described swivel nut is set on the pull bar, and be placed in and draw in the horse sleeve, described anchor ear is set in and draws outside the horse sleeve; Each described pressure roller draws the end of horse to be equipped with a groove, adapts with bearing inner race after the two groove obvolvents, and can block bearing inner race, and the diameter of described pull bar is less than the diameter of bearing inner race.
Advantage of the present utility model is:
Simple to operate, laborsaving; The bearing inner race that is stuck on the roller shaft can be taken off smoothly, and do not damage roller shaft, can reduce equipment cost greatly simultaneously, and the service life of improving equipment.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram after the utility model is opened.
[specific embodiment]
See also illustrated in figures 1 and 2ly, embodiment of the present utility model is described in detail.
As depicted in figs. 1 and 2, the related a kind of roller shaft of the utility model draws the horse device with bearing, the described horse device that draws cooperates roller shaft 10 and bearing (not shown) to use, be provided with inner ring 20 in the described bearing, the described horse device that draws comprises that two semi-cylindrical pressure rollers draw horse 1, a pull bar 2, a swivel nut 3 and an anchor ear 4, described two pressure rollers draw horse 1 to fill the span of a man's arms to form a hollow cylinder and draw horse sleeve 5, described pull bar is provided with screw thread, described swivel nut 3 is set on the pull bar 2, and be placed in and draw in the horse sleeve 5, described anchor ear 4 is set in and draws outside the horse sleeve 5; Each described pressure roller adapts with bearing inner race 20 after drawing the end of horse 1 to be equipped with 11 obvolvents of a groove 11, two grooves, and can block bearing inner race 20, and the diameter of described pull bar 2 is less than the diameter of bearing inner race 20.
During use, bearing inner race 20 is enclosed within the groove 11, the bottom of pull bar 2 props up the roller shaft 10 that blocks in the bearing inner race 20, two pressure rollers draw horse 1 to fill the span of a man's arms then, again anchor ear 4 are set in two pressure rollers and draw horse 1, then rotate swivel nut 3, make swivel nut 3 and pull bar 2 that relative motion take place, roller shaft 10 is ejected.
The utility model, simple to operate, laborsaving; The bearing inner race that is stuck on the roller shaft can be taken off smoothly, and do not damage roller shaft, can reduce equipment cost greatly simultaneously, and the service life of improving equipment.
Though more than described the specific embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
