Description
Technical field
The utility model relates to expansion set technical field, especially a kind of combination separate type expansion set.
Background technique
Connection in machine driving carrys out passing movement generally by key connection, using key connection mode, due to needing
Process keyway on axis and wheel hub, thus reduce the intensity of workpiece, and bearing capacity again by the shearing of key itself and
The limitation of crushing strength.Since key connection axially position is poor, shaft hole matching often selects to be interference fitted, and when installation needs to heat,
With greater need for professional drawbench, or even destructive disassembly when disassembly.As a result of which foreign countries develop one in the five, sixties
Kind Novel connection type, it may be assumed that expansion set connection.Expansion set is no key connection, and inner sleeve and housing cooperate with axis and wheel hub respectively, by twisting
Tight high-strength screw, so that swelling and reducing respectively with the jacket and inner sleeve of cone match, to generate interference with axis and wheel hub
Amount transmits the resultant force of torque, axial force or both by the huge frictional force that the pressure between expansion set and axis and wheel hub generates.
When disassembly is desired, the conical surface of inner-outer sleeve is separated by demounting bolt.
But need to install the expansion set of one group or multiple groups or more in many complicated mechanical equipments to guarantee connection
Intensity, the problem of will result in set-up time long, low efficiency in this way, and need the two neighboring expansion set of higher-strength junction
Between there is no be connected with each other structure, if one of expansion set damage, another expansion set then because intensity will not enough fail,
To cause economic loss, equipment fault or even major accident.

Specific embodiment
The technical solution of the utility model, but the protection scope of the utility model are described in further detail with reference to the accompanying drawing
It is not limited to as described below.
As shown in Figure 1, a kind of combination separate type expansion set is by expansion set I 1, fixing sleeve 2, inner ring sleeve 3, exterior ring cap 4, check bolt
5, tapered surface 6, housing 7, inner sleeve 8, tight fixed bolt 9, fastening block 10, threaded hole 11 and expansion set II 12 form.
A kind of connection type combining separate type expansion set is as follows:
A kind of combination separate type expansion set includes expansion set I 1, expansion set II 12 and the fixation for connecting expansion set I 1 and expansion set II 12
Set 2.
The expansion set I 1 and expansion set II 12 include inner ring sleeve 3, exterior ring cap 4 and several check bolts 5, the inner ring sleeve
3 in the exterior ring cap 4, and the both ends of 4 inner wall of both ends and exterior ring cap of 3 outer wall of inner ring sleeve are tapered surface 6, described
The tapered surface 6 of inner ring sleeve 3 and exterior ring cap 4 tightly fits in together；It is peripherally disposed on the inner ring sleeve 3 to have several logical
Hole, peripherally disposed on the exterior ring cap 4 to have several and the one-to-one screw hole of through-hole, each described check bolt
