Background technology
Axle sleeve is the tubular machine components being sleeved in shaft, is an important component of sliding bearing, and axle sleeve is whole
Body formula structure and split structure, monolithic construction are only used for the shorter shaft of length, and split structure as shown in Figure 1,
It includes first segment axle sleeve 1 and the second nodal axisn set 2, and the right part of first segment axle sleeve 1 offers threaded hole, the second nodal axisn set 2
Left part is provided with boss, and external screw thread is provided on the cylinder of boss, and the second nodal axisn set 2 is threadedly coupled through boss with threaded hole solid
Due on first segment axle sleeve 1.Due to using two nodal axisn sets, length to be lengthened, therefore it is suitable for long shaft.In order to ensure
One nodal axisn set 1 connect secured with the second nodal axisn set 2, usually twists the two very tight, this brings to detaching two nodal axisn sets again
It is difficult.If that twists is too loose, it is easy to loosen in the axial direction, it is very dangerous, therefore there are certain contradictions.Therefore there is an urgent need for one kind
Convenient disassembly, safe and reliable axle sleeve.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provide it is a kind of it is compact-sized, be suitable for long shaft,
It is connected firmly, safe and reliable extension type axle sleeve.
The purpose of this utility model is achieved through the following technical solutions：A kind of extension type axle sleeve, it includes first segment
The left part of axle sleeve and the second nodal axisn set, the second nodal axisn set axis hole offers annular groove, the cylinder of the first segment axle sleeve
On offer annular stopper, on annular stopper and lower end disposed thereon is both provided with limiting slot, and first segment axle sleeve is inserted in ring
In shape slot, the upper and lower sides of annular groove are both provided with groove, and groove is located at the left side of limiting slot, Vertical Spring is installed in groove,
The bottom of Vertical Spring is fixed with steel ball, and steel ball is pressed under the elastic force of Vertical Spring on first segment axle sleeve, and the annular is stopped
Multiple crossed strips are distributed between the bottom of mouth and the left side of the second nodal axisn set and around the circumferencial direction of annular stopper, it is described
It is cased with retaining ring between first segment axle sleeve and the second nodal axisn set.
The first segment axle sleeve is identical as the outer diameter that the second nodal axisn covers.
The first segment axle sleeve and the second nodal axisn set are coaxially disposed.
The crossed strip is uniformly distributed.
The depth of the groove is more than the depth of limiting slot.
The utility model has the following advantages：The utility model is compact-sized, suitable for long shaft, be connected firmly, safety
Reliably.

Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Fig. 2 ~ 5, a kind of extension type axle sleeve, it includes that first segment axle sleeve 1 and the second nodal axisn cover 2, described second
The left part that nodal axisn covers 2 axis holes offers annular groove 3, and annular stopper 4 is offered on the cylinder of the first segment axle sleeve 1, annular
On seam allowance 4 and lower end disposed thereon is both provided with limiting slot 5, and first segment axle sleeve 1 is inserted in annular groove 3, annular groove 3 it is upper
Downside is both provided with groove 6, and the depth of groove 6 is more than the depth of limiting slot 5, and groove 6 is located at the left side of limiting slot 5, in groove 6
It is installed with Vertical Spring 7, the bottom of Vertical Spring 7 is fixed with steel ball 8, and steel ball 8 presses on first under the elastic force of Vertical Spring 7
On nodal axisn set 1, between the bottom of the annular stopper 4 and the left side of the second nodal axisn set 2 and around the circumferencial direction of annular stopper 4
Multiple crossed strips 9 are distributed with, crossed strip 9 described in the present embodiment is uniformly distributed, 1 and second nodal axisn of the first segment axle sleeve
It is cased with retaining ring 10 between set 2.
As shown in Fig. 2 ~ 5, first segment axle sleeve described in the present embodiment 1 is identical as the outer diameter of the second nodal axisn set 2, and described first
2 coaxial arrangement of nodal axisn set 1 and the second nodal axisn set.
The course of work of the utility model is as follows：First segment axle sleeve 1 as shown in Figure 3 and the second nodal axisn cover 2 total length compared with
It is short, it can be installed in short shaft.When to be installed in long shaft, retaining ring 10 is unloaded, the second nodal axisn set 2 is in lateral bullet
It moves right along annular stopper 4 under the effect of 9 spring restoring force of spring, steel ball 8 moves right also along annular stopper 4, when groove 6
With limiting slot 5 relatively after, steel ball 8 is pressed under the elastic force of Vertical Spring 7 in limiting slot 5, to limit the second nodal axisn set 2
Axial movement, first segment axle sleeve 1 and the second nodal axisn set 2 total length lengthen as shown in figure 5, at this time can be by long shaft by the right side
It turns left and the second nodal axisn is sequentially passed through to cover 2 axis hole, the axis hole of first segment axle sleeve 1, to realize the installation of long shaft；When to shorten away from
When length, need to only push away the second nodal axisn set 2 to the left makes steel ball 8 be moved out from limiting slot 5, and compresses crossed strip 9, works as crossed strip
After 9 are pressed onto extreme position, upper locking ring 10 is covered between first segment axle sleeve 1 and the second nodal axisn set 2, realizes the light of two axle sleeves
Shorten, therefore the telescopic axle sleeve is split type compared to traditional, overcomes the defect of original engagement thread, is suitable for long shaft
Installation, and be easily achieved growth or shortening, the operation is more convenient.
