Abstract
The utility model relates to the manufacturing technology of a motor and discloses a dismounting apparatus for a cylindrical roller bearing. The dismounting apparatus comprises a screw rod. A top plate passes through one end of the screw rod; the screw rod is provided with a nut pushing the external end surface of the top plate; at least two top rods are evenly distributed on the internal end surface of the top plate; the other end of the screw rod is fixedly provided with a tooth disc; tooth columns are evenly distributed on the periphery of the tooth disc; the tooth columns are arranged between two adjacent roller columns of the cylindrical roller bearing; and an addendum circle diameter of the tooth disc is larger than an internal ring diameter of the cylindrical roller bearing. By the use of the dismounting apparatus for the cylindrical roller bearing, the cylindrical roller bearing can be easily dismounted and a dismounting process is simplified.
Description
Technical field
The utility model relates to motor manufacturing technology, particularly a kind of provision for disengagement for cylinder roller bearing.
Background technology
In the assembling process of motor, because a lot of reasons need to be changed cylinder roller bearing; The inner ring of cylinder roller bearing is easy to take off with rotating shaft, and the outer ring of cylinder roller bearing is interference fits structure with bearing block, and this type of cylinder roller bearing is unidirectional installation, when dismounting, can only cylinder roller bearing be taken out from a direction, when dismounting, a lot of conventional instruments are had no way of doing it, even if adopt certain methods to pull down the matching surface that also easily weares and teares, reduce quality of fit, cause dismounting and change cylinder roller bearing very inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of provision for disengagement for cylinder roller bearing, and this device can reach the object of easy removal cylinder roller bearing, has simplified unloading process.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme to be reached.
For a provision for disengagement for cylinder roller bearing, it is characterized in that, comprise screw rod, one end of described screw rod is penetrated with top board, and is provided with the nut for promoting described top board outer face, and the inner face of described top board is uniform is provided with at least two push rods; The other end of described screw rod is installed with fluted disc, described fluted disc be circumferentially evenly equipped with tooth post, described tooth post is between two adjacent rollers of described cylinder roller bearing, the tip diameter of described fluted disc is greater than the inner ring external diameter of described cylinder roller bearing.
Feature of the present utility model and further improvement are:
Described top board is circular, and the outside diameter of described top board is greater than the outer ring external diameter of cylinder roller bearing.
The axial length of described push rod is greater than the axial length of cylinder roller bearing.
Cylinder roller bearing disassembling fixture of the present utility model, first fluted disc is adjusted, gap between its roller from cylinder roller bearing is passed through, by an angle of fluted disc rotation, make it against the roller on cylinder roller bearing, nut is arranged on to top board outside, slow circumvolve nut moves screw axial, under the pulling force effect of screw rod, cylinder roller bearing is slowly pulled out in cylinder roller bearing seat, reaches the object of easy removal cylinder roller bearing.

Detailed description of the invention
Cylinder roller bearing mainly comprises outer ring, inner ring, retainer, roller, and wherein inner ring and outer ring are separable, is convenient to installation and removal, and the inner headed face of outer ring is provided with raceway, and roller is arranged on retainer, and retainer is installed on outer ring, and roller is in raceway inside.
With reference to Fig. 1, it is the structural representation of a kind of provision for disengagement for cylinder roller bearing of the present utility model.This device comprises screw rod 1, and one end of screw rod 1 is penetrated with top board 3, and is provided with the nut 4 for promoting top board 3 outer faces, uniform at least two push rods 5 that are provided with of inner face of top board 3, and the present embodiment is symmetrically arranged with two push rods; The other end of screw rod 1 is installed with fluted disc 2, fluted disc 2 be circumferentially evenly equipped with tooth post, tooth post is between two adjacent rollers 8 of cylinder roller bearing 6, the tip diameter of fluted disc 2 is greater than the inner ring external diameter of cylinder roller bearing 6 and is less than the outer ring internal diameter of cylinder roller bearing 6, the root diameter of fluted disc 2 is less than the inner ring external diameter of cylinder roller bearing 6, make fluted disc 2 can pass through the gap between the roller 8 on cylinder roller bearing 6, and can block the roller 8 on cylinder roller bearing 6 at rotation rear tooth disk 2.
The axial length of push rod 5 is greater than the axial length of cylinder roller bearing 6, makes to use this frock cylinder roller bearing 6 can be taken out completely.
As shown in Figure 2, this frock in use, is first adjusted fluted disc 2, the gap between its roller 8 from cylinder roller bearing 6 is passed through, as shown in Figure 3; Fluted disc 2 is rotated to an angle, make it against the roller 8 on cylinder roller bearing 6, as shown in Figure 4; Then load onto top board 3, make push rod 5 withstand bearing block 7, mounting nuts 4 is also tightened, slow circumvolve nut 4 moves axially screw rod 1, under the pulling force effect of screw rod 1, roller 8 drives the outer ring of cylinder roller bearing 6 outwards to move, thus by cylinder roller bearing 6 from the interior slow pull-out of bearing block 7, reach the object of easy removal cylinder roller bearing 6.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art, under the enlightenment of description, in the case of not departing from the scope that the utility model claim protects, can also make a variety of forms, and these all belong to the row of the utility model protection.
