Abstract
The invention discloses a bearing puller. A bearing can be supported and pulled out through a plurality of bearing supporting blocks. Compared with a hooking-claw type bearing puller, the bearing puller is better in stability and capable of bearing larger force, and meanwhile the bearing puller is higher in use strength and suitable for detaching the bearing under the condition that the bearing is tightly matched.
Description
Technical field
The present invention relates to a kind of bearing extractor, belong to the machine tool field.
Background technology
Traditional bearing extractor is that bearing puller general employing 2 pawls or the tension of 3 pawls are extracted by the bearing that screw rod will be enclosed within on axostylus axostyle, and the mode of pawl formula chucking can cause damage and the danger of axostylus axostyle in this case in the situation that bearing holder (housing, cover) is taken over the excessive situation that collapses tooth or slippage that easily causes of the power of straining at.
Summary of the invention
The object of the invention is to:
A kind of technical scheme that can overcome the above problems is provided.
The present invention realizes by the following method:
A kind of bearing extractor, described bearing extractor comprises screw rod, shell and some bearings pieces, described screw rod is flexibly connected by screw thread and shell, described screw rod comprises for the extruding axostylus axostyle extracts the pressed end of bearing and the operating side of rotary screw, described enclosure is provided be used to the cavity that holds bearing near the pressed end position, described some bearings pieces pass shell and stretch into cavity inside, be symmetrical arranged and be positioned on same horizontal plane with respect to screw rod, described some bearings pieces and shell are flexibly connected.
As further innovation of the present invention, described some bearings pieces are fixed by securing member and shell.
As further innovation of the present invention, described securing member is screw.
As further innovation of the present invention, the quantity of described bearings piece is 3 multiple.
As further innovation of the present invention, described pressed end head is hemispherical.
As further innovation of the present invention, described shell is cast steel.
As further innovation of the present invention, described screw rod and some bearings pieces are the brass material.
Beneficial effect
1. the present invention realizes the support of bearing and extracts by several bearings pieces, than the bearing puller of identical hook pawl formula, stability of the present invention is better, and the power that can bear is larger, working strength is higher simultaneously, the dismounting of the state lower bearing that suitable bearing fit is tighter.
2. in order to guarantee the stability of bearing drawing process middle (center) bearing back-up block, and the bearings piece facilitate mobility to be fit to the bearing of multiple diameter, bearings piece of the present invention is fixed by screw, has the convenience of adjusting and the stability of operation concurrently.
3. cause pulling force inhomogeneous and produce slippage when arranging because leg-of-mutton stability prevents similar square, the present invention says that the quantity of bearings piece is 3 multiple.
4. in order to reduce the damage to workpiece when working of this bearing extractor, the parts that contact with bearing with axostylus axostyle in the present invention have all adopted the brass material, have the soft on rigidity and surface concurrently.
Description of drawings
Fig. 1 is front view of the present invention.
Fig. 2 is upward view of the present invention.
In figure: 1, screw; 2, screw rod; 3, bearings piece; 4, pressed end; 5, shell.
The specific embodiment
Be described further below in conjunction with accompanying drawing:
as shown in Figure 1 and 2, described bearing extractor comprises screw rod 2, shell 5 and some bearings pieces 3, described screw rod 2 is flexibly connected by screw thread and shell 5, described screw rod 1 comprises for the extruding axostylus axostyle extracts the hemispherical head pressed end 4 of bearing and the operating side of rotary screw, described shell 5 is inner to be provided be used to the cavity that holds bearing near pressed end 4 positions, described three bearings pieces 3 pass shell and stretch into cavity inside, be symmetrical arranged and be positioned on same horizontal plane with respect to screw rod 2, described some bearings pieces 3 are flexibly connected with shell 5, and by screw 1 locking.
In use, the shell of this extractor 5 cavitys are socketed on axostylus axostyle, and bearings piece 3 are loosened until with bearing, contact, lock-screw 1 afterwards, and rotation spiral shell 2 takes off bearing from axostylus axostyle.
Claims (7)
