Abstract
Title of the present utility model is that a kind of bearing pulls away device, relates to specifically one for NU series bearing, and inner ring is without the device that pulls away of rib cylinder roller bearing.It is mainly to solve to utilize the inertia that knocks end cap that bearing is taken out, and easily makes end cap distortion, causes damage to be scrapped, inefficient problem.The utility model is on one end of screw rod, to be connected with a support, a pallet is installed on the other end of screw rod, this pallet is connected on screw rod by tray nut, and the curve shape of pallet cylindrical matches with the curve shape of bearing radial section inner ring to be pulled away.The utility model drives pallet by screw rod, make pallet be moved to bearing roller to be pulled away bottom, hold the roller of bearing to be pulled away, utilize support as external support, make tray nut drive pallet to rise by spanner or pneumatic tools rotary screw, the bearing in bearing (ball) cover to be pulled away is extracted; Pallet of the present utility model can carry out dismounting and change according to the bearing of different model.
Description
Technical field
The utility model relates to a kind of bearing outer ring and pulls away device, relates to specifically a kind ofly for for NU series bearing, and inner ring is without the device that pulls away of rib cylinder roller bearing.
Background technology
Bearing outer ring is separated from bearing with end cover is indoor because bearing returns man-hour requirement in existing production scene, be all to utilize the inertia that knocks end cap that bearing is taken out in the past, is easy to make end cap distortion, due to shaft strength inequality, likely causes damage to be scrapped.And for coordinating tighter bearing to utilize the said method dismounting effort of more taking a lot of work, efficiency is low.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and a kind of manufacture craft providing is simple, time saving and energy saving, lightweight, has a kind of bearing dismounting tool of versatility.
Technical solution of the present utility model is: on one end of screw rod, be connected with a support, a pallet is installed on the other end of screw rod, this pallet is connected on screw rod by tray nut, and the curve shape of pallet cylindrical matches with the curve shape of bearing radial section inner ring to be pulled away.
Support described in technical solution of the present utility model is that a diameter is greater than bearing diameter to be pulled away, and is less than the cylinder of bearing (ball) cover diameter to be pulled away, and support is connected on screw rod by plane bearing.
On screw rod described in technical solution of the present utility model, with six square toes, the screw thread on screw rod is trapezoidal thread.
When the utility model uses, rotary screw, can make pallet be displaced downwardly to bearing roller to be pulled away bottom by the position, gap of retainer to be pulled away and roller, and rotary-tray can make it hold the roller of bearing.Utilize support as external support, by spanner or the pneumatic tools rotary screw with sleeve, make tray nut drive pallet to rise, pallet holds bearing roller to be pulled away, transmit even climbing power by retainer to be pulled away, outer ring and drive bearing outer ring whole to be pulled away to rise, thereby the bearing in bearing (ball) cover to be pulled away is extracted; Pallet of the present utility model can be dismantled, and changes according to the bearing of different model and specification; The utility model, owing to plane bearing being housed between screw rod and support, makes bolt rotary flexible, reduces wearing and tearing, life-extending.

Detailed description of the invention
As shown in Figure 1, 2, 3, on one end of screw rod 1, be connected with support 2, support 2 is connected on screw rod 1 by plane bearing, and support 2 is that a diameter is greater than bearing 4 diameters to be pulled away, and is less than the cylinder of bearing 4 end cap 3 diameters to be pulled away, on screw rod 1 with six square toes, when use, can, with the spanner of dimension, also can use sleeve and pneumatic tools, screw rod 1 be rotated more convenient, on while screw rod 1, also with trapezoidal thread, energy is carry-over moment preferably; A pallet 5 is installed on the other end of screw rod 1, the tray nut 6 that this pallet 5 is threaded connection on screw rod 1 is connected on screw rod 1, adjust the upper and lower position of tray nut 6 on screw rod 1, can drive pallet 5 to move up and down on screw rod 1, the curve shape of pallet 5 cylindricals matches with the curve shape of bearing 4 radial section inner rings to be pulled away, be that pallet 5 can move up and down vertically in the inner ring of bearing 4 to be pulled away, and in the time that pallet 5 rotates an angle, pallet 5 can interlock with bearing 4 to be pulled away again; Tray nut 6 is unloaded from screw rod 1, can dismantle pallet 5, can change pallet 5 easily according to the bearing to be pulled away 4 of different model and specification.
Operation principle: when use, screw rod 1 of the present utility model is passed from the center of bearing 4 to be pulled away, support 2 is supported on the end cap 3 of bearing 4 to be pulled away, because the curve shape of pallet 5 cylindricals and the curve shape of bearing 4 inner rings to be pulled away match, while being rotated counterclockwise screw rod 1, can make tray nut 6 drive pallet 5 to move down from the retainer of bearing 4 to be pulled away and the position, gap of roller, tray nut 6 and pallet 5 are moved down in the time pulling away bearing 4 roller bottom surface, rotary-tray 5, clockwise rotate screw rod 1 simultaneously, make pallet 5 hold the roller of bearing 4 to be pulled away, utilize support 2 as external support, support the end cap 3 of bearing 4 to be pulled away, make bearing 4 rollers to be pulled away by its retainer, climbing power is transmitted in outer ring, drive on the whole outer ring of bearing 4 to be pulled away and rise, thereby the bearing in bearing 4 end caps to be pulled away is extracted.
