Description
Technical field
The utility model relates to crankshaft protection technology field, in particular to a kind of crankshaft protective jacket.
Background technique
The placement of crankshaft is mainly realized by bearing against two spindle ends on rack, will lead to song when putting crankshaft
There is hard contact in the main shaft of axis and rack, and so as to cause colliding with and wear to crankshaft, in the process of transport crankshaft, this is asked
Topic is particularly acute, and often will appear some substandard products, causes very huge economic loss.
Summary of the invention
For disadvantages described above, the purpose of the utility model is to provide a kind of crankshaft protective jackets, it is intended to solve in the prior art
Problem Technical problem of colliding with when crankshaft is placed.
In order to solve the above technical problems, the technical solution of the utility model is:
The medial and lateral of a kind of crankshaft protective jacket, the intermediate ring set including rigid material, intermediate ring set are equipped with flexible material
Inner sleeve and housing, intermediate ring set include two collar extension portions of coaxial arrangement and several connections being connected between two collar extension portions
Bar, several connecting rods are circumferentially arranged around the axis of intermediate ring set, and the both ends of inner sleeve are fixed in the opposite end in two collar extension portions
On face, circumferentially wavy structure, the outer projection correspondence of wavy shaped configuration are connected to adjacent two connecting rod to inner sleeve
Between.
Wherein, the opening in collar extension portion does chamfered.
Wherein, outer casing inner wall is adhered on intermediate ring set.
Wherein, housing is polyurethane gum cover.
Wherein, the outer end of the outer projection of wavy shaped configuration is adhered to outer casing inner wall.
Wherein, the inner end of the internal protrusion of wavy shaped configuration is consistent with cylindrical surface profiling.
Wherein, the front and back ends of the internal protrusion of wavy shaped configuration do chamfered.
Wherein, inner sleeve is ethylene-propylene-diene monomer gum cover.
After above-mentioned technical proposal, the beneficial effects of the utility model are:
Since the utility model crankshaft protective jacket includes the intermediate ring set of rigid material, the medial and lateral of intermediate ring set are equipped with
The inner sleeve and housing of flexible material, the global shape of crankshaft protective jacket is maintained by intermediate ring set, and crankshaft protection is avoided to extract
Existing deformation, is contacted by inner sleeve with the spindle Flexible of crankshaft, and the protection to crankshaft is formed, and is carried out by housing and rack flexible
Contact, forms the protection to rack, and intermediate ring set includes two collar extension portions of coaxial arrangement and is connected between two collar extension portions
Several connecting rods, several connecting rods circumferentially arrange around the axis of intermediate ring set, and the both ends of inner sleeve are fixed in two rings
On the opposing end surface of oral area, circumferentially wavy structure, the outer projection correspondence of wavy shaped configuration are connected to inner sleeve
Between adjacent two connecting rod, inner sleeve is allowed to carry out certain elastic deformation by wavy shaped configuration, to promote inner sleeve
To the chuck(ing) capacity of crank spindle, crankshaft protective jacket is avoided to be detached from from crankshaft.
Since the opening in collar extension portion does chamfered, so that crankshaft protective case is easier to be socketed in the main shaft of crankshaft
On.
Since the outer end of the outer projection of wavy shaped configuration is adhered to outer casing inner wall, avoid protective jacket in set termination process
In, the frictional force between crankshaft and inner sleeve leads to the fold situation of inner sleeve axial deformation appearance.
Since the inner end of the internal protrusion of wavy shaped configuration is consistent with cylindrical surface profiling, guarantee protective jacket in the master of crankshaft
Fastness after axis socket.
In conclusion the utility model solve in the prior art crankshaft place when occur the technical issues of colliding with, this reality
Effective protection can be carried out to crankshaft with novel, reduce collide with wear problem of the crankshaft when putting, ensure that the matter of crankshaft
Amount.
Detailed description of the invention
Fig. 1 is a kind of Structure explosion diagram of crankshaft protective jacket of the utility model；
Fig. 2 is a kind of sectional view of crankshaft protective jacket of the utility model.
In figure, 1- inner sleeve, 10- outer projection, 11- internal protrusion, the centre 2- ring set, 20- collar extension portion, 21- connecting rod, 3-
Housing.
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
The orientation when orientation being related in this specification is worked normally with a kind of crankshaft protective jacket of the utility model is
Standard does not limit orientation when its storage and transport, only represents opposite positional relationship, do not represent absolute positional relationship.
As Fig. 1 and Fig. 2 jointly shown in, a kind of crankshaft protective jacket, including inner sleeve 1, intermediate ring set 2 and 3 three parts of housing,
Inner sleeve 1 is set in the inside of intermediate ring set 2, and housing 3 is socketed on the outside of intermediate ring set 2.
As Fig. 1 and Fig. 2 jointly shown in, intermediate ring set 2 is rigid material, and preferably steel frame construction, intermediate ring set 2 includes
Two collar extension portions 20 and 21 three parts of connecting rod, connecting rod 21 be it is multiple, multiple connecting rods 21 are in uniform circumferential arrangement, and whole
Body is in rail-like structure, and collar extension portion 20 is circular ring structure, and two collar extension portions 20 respectively correspond the both ends for being fixed in rail-like structure
On, in present embodiment, collar extension portion 20 is equipped with mounting hole, and connecting rod 21 is plugged in mounting hole, and is carried out by anaerobic adhesive
It is fixed.
