Abstract
The utility model relates to a key connection structure, including axle, wheel hub, key, the key connect the transmission in order to realize the moment of torsion with axle and wheel hub, the key be spherical, the surface of axle is provided with the semi -circular groove according to the processing of spherical key size, is provided with the round ARC through groove according to the processing of spherical key size along the axial on wheel hub's the hole, some installs spherical key at epaxial semi -circular inslot, partly and wheel hub arc wall cooperatees. The utility model discloses epaxial processing volume can be effectively reduced, the space is practiced thrift, reduce the stress concentration that wheel hub went up the keyway, improve life.
Description
Technical field
This utility model relates to a kind of attachment structure, a kind of bonded structure, can ensure the strong of link position
Degree.
Background technology
Bonded is widely used a kind of propeller boss type of attachment, bonded realize between axle and wheel hub circumferentially positioned,
Moment of torsion can be transmitted simultaneously.The shape of bonded button can be divided into the types such as flat key connection, woodruff key connection.Bonded need at axle and
Processing groove on wheel hub, the cross sectional shape of groove is generally rectangular cross-section, and on axle, the groove size of processing is big, and the sharp corner at groove can exist simultaneously
Stress is concentrated, and reduces axle and wheel hub intensity.
Summary of the invention
The purpose of this utility model is to design a kind of bonded structure, preferably solves to add section chief on the axle of bonded existence
Groove, stress collection are medium causes axle and wheel hub intensity to reduce problem.
The technical solution of the utility model is, bonded structure includes axle, wheel hub, key, and axle and wheel hub are connected by described key
Connecing to realize the transmission of moment of torsion, described key is spherical, and the outer surface of axle is provided with the semi-circular groove by spherical key dimensioned,
The axially disposed arc-shaped slot pass having by spherical key dimensioned on the endoporus of wheel hub, a spherical key part be mounted on an axle half
In circular trough, a part matches with wheel hub arcuate groove.
Axle of the present utility model is circular arc with the position installing key of setting on wheel hub, reduces processing capacity on axle, and exempts from
Wedge angle occurs, reduces stress and concentrate, the effective axle solving bonded existence is processed elongated slot, stress collection is medium causes axle and wheel
Hub intensity reduces problem.This utility model is effectively reduced processing capacity on axle, saves space；Reduce the stress collection of keyway on wheel hub
In, improve service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
As it can be seen, bonded structure includes axle 1, wheel hub 3, key 2, described key 2 axle 1 and wheel hub 3 are connected with
Realizing the transmission of moment of torsion, described key 2 is spherical, and the outer surface of axle 1 is provided with the semicircle by spherical key 2 dimensioned
Groove, the axially disposed arc-shaped slot pass having by spherical key 2 dimensioned on the endoporus of wheel hub 3, spherical key 2 part is installed
In semi-circular groove on axle 1, a part matches with wheel hub 3 arcuate groove.
