Description
Technical field
The utility model is related to belt pulley parts technical fields, more particularly to belt pulley expansion sleeve.
Background technology
Expansion sleeve is a kind of advanced basic components, in taking turns the connection with axis, increases the pressure of the conical surface by bolt,
Since its installation and dismounting do not have to compared to more convenient by other tools, and by the joyous of vast manufacturer and client
It meets, but spoilage is very high in the use of high intensity, therefore, quality is also required to improve therewith.
Invention content
And, the utility model provides a kind of high quality, prolongs in view of the above-mentioned defects in the prior art
The belt pulley expansion sleeve of long service life of equipment.
Technical solution adopted by the utility model to solve its technical problems is：Belt pulley expansion sleeve, including belt pulley and
Expansion sleeve in belt pulley, which is characterized in that the expansion sleeve is coaxially disposed with belt pulley, and the belt pulley is equipped with more
A threaded hole, the expansion sleeve are equipped with bolt mounting holes corresponding with multiple threaded holes, and the expansion sleeve passes through with belt pulley
Bolt is fixedly connected, and the expansion sleeve is tapered, and the expansion sleeve is axially arranged with opening, and the belt pulley accommodates expansion sleeve
Endoporus be also tapered.
Further, the taper of the expansion sleeve is more than the taper of endoporus on belt pulley.
Further, the shaft-driven keyway of at least one donating bond is equipped in the expansion sleeve.
The utility model has the beneficial effects that：The prior art is compared, the belt pulley expansion sleeve of the utility model has following
Advantage：Expansion sleeve and belt pulley are fixed by bolt, belt pulley all has taper with expansion sleeve, and the taper of expansion sleeve is more than
The taper of belt pulley, expansion sleeve are axially arranged with opening, therefore, can will be connected between expansion sleeve and belt pulley after bolt is tightened solid
It is fixed, in dismounting, bolt is backed out, convenient for taking out expansion sleeve.

Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to specific embodiment of the present utility model, furthers elucidate the utility model
The advantages of and outstanding contributions compared with the existing technology, it is possible to understand that, following embodiments is only preferable to the utility model
The detailed description of embodiment should not be construed as any restrictions to technical solutions of the utility model.This practicality is not being departed from
Under the premise of new design is conceived, various modifications and change that ordinary people in the field makes the technical solution of the utility model
Into should fall within the protection scope of the present utility model, the claimed technology contents of the utility model are all documented in
In claims.
As shown in Figs. 1-5, belt pulley expansion sleeve, including belt pulley（1）And it is set to belt pulley（1）Interior expansion sleeve（2）, swollen
It is fixed（2）With belt pulley（1）Coaxial arrangement, belt pulley（1）It is equipped with multiple threaded holes（12）, expansion sleeve（2）Be equipped with it is more
A threaded hole（12）Corresponding bolt mounting holes（21）, expansion sleeve（2）With belt pulley（1）Pass through bolt（3）It is fixedly connected, swelling
Set（2）It is tapered, expansion sleeve（2）It is axially arranged with opening（22）, belt pulley（1）Accommodate expansion sleeve（2）Endoporus（11）?
It is tapered.
Further, expansion sleeve（2）Taper be more than belt pulley（1）Upper endoporus（11）Taper.
Further, expansion sleeve（2）The shaft-driven keyway of donating bond there are one inside setting（23）.
When installation, expansion sleeve is put into belt pulley, makes the threaded hole on the bolt mounting holes and belt pulley on expansion sleeve
It is corresponding, it is then screwed into bolt, since belt pulley and expansion sleeve all have taper, and the taper of expansion sleeve is more than the cone of belt pulley
Degree, expansion sleeve are axially arranged with opening, therefore, can will be connected and fixed, dismantle between expansion sleeve and belt pulley after bolt is tightened
When, bolt is backed out, convenient for taking out expansion sleeve.
