Abstract
The invention discloses a bearing pulling-out device, and particularly relates to a pulling-out device used for NU-series bearings, namely cylindrical roller bearings without flanges on the inner rings. The bearing pulling-out device mainly aims to solve the problems that as bearings are taken out through inertia of knocking end covers, the end covers are prone to deformation, then the end covers are damaged and scrapped, and efficiency is low. A support is connected to one end of a screw rod, a tray is installed at the other end of the screw rod and connected to the screw rod through a tray nut, and the curve shape of the outer circle of the tray is matched with the curve shape of the inner ring of the radial cross section of a bearing to be pulled out. The screw rod is used for driving the tray, so that the tray moves to the bottom of a pin roller of the bearing to be pulled out and drags the pin roller of the bearing to be pulled out, the support serves as the external support, the tray nut drives the tray to ascend by rotating the screw rod through a spanner or a pneumatic tool, and the bearing in an end cover of the bearing to be pulled out is pulled out. The tray can be detached and replaced according to bearings of different types.
Description
Technical field
The present invention relates to a kind of bearing outer ring and pull away device, relate to a kind of for for NU series bearing specifically, namely inner ring pulls away device without rib cylinder roller bearing.
Background technology
Because bearing returns man-hour requirement, bearing outer ring is separated from bearing with end cover indoor in existing production scene, be all utilize the inertia knocking end cap to be taken out by bearing in the past, be easy to end cap is out of shape, because shaft strength is uneven, likely cause damage to be scrapped.And utilizing said method dismounting more to take a lot of work effort for the tighter bearing of cooperation, efficiency is low.
Summary of the invention
The object of the invention is for above-mentioned deficiency, and a kind of manufacture craft provided is simple, time saving and energy saving, lightweight, there is a kind of bearing dismounting tool of versatility.
Technical solution of the present invention is: on one end of screw rod, be connected with a support, the other end of screw rod is provided with a pallet, this pallet is connected on screw rod by tray nut, and the curve shape of pallet cylindrical and the curve shape of bearing radial section inner ring to be pulled away match.
Support described in technical solution of the present invention is that a diameter is greater than bearing diameter to be pulled away, and be less than the cylinder of bearing (ball) cover diameter to be pulled away, support is connected on screw rod by plane bearing.
With six square toes on screw rod described in technical solution of the present invention, the screw thread on screw rod is trapezoidal thread.
When the present invention uses, rotary screw, the position, gap that pallet can be made to pass through retainer to be pulled away and roller is displaced downwardly to bottom bearing roller to be pulled away, and rotary-tray can make it hold the roller of bearing.Utilize support as external support, by spanner or the pneumatic tools rotary screw being with sleeve, tray nut is made to drive pallet to rise, pallet holds bearing roller to be pulled away, transmitting even climbing power by retainer to be pulled away, outer ring drives bearing outer ring whole to be pulled away to rise, thus is extracted by the bearing in bearing (ball) cover to be pulled away; Pallet of the present invention can be dismantled, and the bearing according to different model and specification is changed; The present invention, owing to being equipped with plane bearing between screw rod and support, making bolt rotary flexible, reduces wearing and tearing, life-extending.

Fig. 2 is the postrotational upward view of screw rod in Fig. 1.
Fig. 3 is the upward view in Fig. 1 before screw rod rotation.
Detailed description of the invention
As shown in Figure 1, 2, 3, one end of screw rod 1 is 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 diameter to be pulled away, and is less than the cylinder of bearing 4 end cap 3 diameter to be pulled away, with six square toes on screw rod 1, with the spanner of dimension, also can use sleeve and pneumatic tools, screw rod 1 be rotated more convenient during use, simultaneously on screw rod 1 also with trapezoidal thread, can carry-over moment preferably; The other end of screw rod 1 is provided with a pallet 5, this pallet 5 tray nut 6 be threaded connection on screw rod 1 is connected on screw rod 1, the adjustment upper and lower position of tray nut 6 on screw rod 1, pallet 5 can be driven to move up and down on screw rod 1, the curve shape of pallet 5 cylindrical and the curve shape of bearing 4 radial section inner ring to be pulled away match, namely pallet 5 can move up and down vertically in the inner ring of bearing 4 to be pulled away, and when pallet 5 rotates an angle, pallet 5 can interlock with bearing 4 to be pulled away again; Unloaded from screw rod 1 by tray nut 6, namely can dismantle pallet 5, the bearing to be pulled away 4 according to different model and specification can be changed pallet 5 easily.
Operation principle: during use, the center of screw rod 1 of the present invention from bearing 4 to be pulled away is passed, support 2 is supported on the end cap 3 of bearing 4 to be pulled away, because the curve shape of pallet 5 cylindrical and the curve shape of bearing 4 inner ring to be pulled away match, when being rotated counterclockwise screw rod 1, tray nut 6 can be made to 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 is made to move down in time pulling away bearing 4 roller bottom surface, rotary-tray 5, rotate clockwise screw rod 1 simultaneously, pallet 5 is made to 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 roller 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, thus the bearing in bearing 4 end cap to be pulled away is extracted.
