Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of combined type input shaft.
Background technique
For input shaft for transmitting power, existing input shaft is usually a monolithic construction.If the both ends ruler of input shaft
When very little diversity ratio is larger, entire input shaft difficulty of processing is caused to become larger in this way, yield rate is relatively low.
In order to solve this problem, people have devised split type input shaft, i.e. large scale end and small size end is independent
Large scale end, is fixedly connected with by production with small size end again after molding.But being solidly connected mode is usually fastener or weldering
It connects.
As can be seen that above-mentioned fixed form precision is not high, it is poor to eventually lead to entire input shaft stability.
Summary of the invention
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, to provide a kind of easy to assembly and stability
High combined type input shaft.
The purpose of this utility model can be realized by the following technical scheme:
A kind of combined type input shaft, including ontology in the shape of a rod, the both ends of the ontology are respectively input terminal and output end,
It is characterized in that, the ontology includes the ontology one and ontology two in the form of annular discs in elongated rod shape, above-mentioned input terminal is located at ontology
Two sides, above-mentioned output end are located at one outer end of ontology, are connected between one inner end of ontology and ontology two by connection structure
It connects.
This input shaft is creative to be connected ontology one with ontology two by connection structure, therefore, ontology one and ontology
Two can independently make, and the two links together again after ontology one and the molding of ontology two.
Obviously, its is compact-sized for entire input shaft, and is connected by connection structure, avoids using bolt or other
Fastener connection, therefore, stability is also relatively high.
Certainly, since output end is located at one outer end of ontology, input terminal is located at two side of ontology.The input shaft energy being composed
Stablize transmission power.
Input terminal is the circumferential teeth being evenly arranged at one outer end of ontology, and output end is circumferentially to be evenly arranged on two outside of ontology
Teeth.
In combinations of the above formula input shaft, one inner end of ontology has the gear edge of protrusion, and above-mentioned ontology two is in disk
There is the convex shoulder of protrusion, two sets of the ontology at one inner end of ontology and above-mentioned gear edge is resisted against convex shoulder on the inside of shape and ontology two
On.
It keeps off in the effect of connection structure and being resisted against on convex shoulder along stable, the final company guaranteed between ontology one and ontology two
Connect stability.
It further include a tubular locking cylinder in combinations of the above formula input shaft, above-mentioned locking cylinder covers on ontology one
And the two is threadedly coupled, the locking cylinder is resisted against on above-mentioned ontology two.
Locking cylinder due to being threaded on ontology one, connective stability is high between the two.
Ontology two is located on ontology one by stable under the action of locking cylinder.
In combinations of the above formula input shaft, washer flexible is also cased on the ontology one, above-mentioned washer is pressed on
Between locking cylinder and ontology two.
In combinations of the above formula input shaft, two end of ontology has recessed attachment base, and above-mentioned washer is located at
At attachment base and washer outside and two outside flush of ontology.
In combinations of the above formula input shaft, the washer is rubber material.
In combinations of the above formula input shaft, the washer is felt materials.
Washer flexible is avoided that rigid contact between ontology two and locking cylinder, and appropriate can also play buffering and make
With further improving the structural stability of entire input shaft.
In combinations of the above formula input shaft, there is the contact knot that can increase frictional resistance between the locking cylinder and washer
Structure.
In combinations of the above formula input shaft, the contact structures include several salient points of locking cylinder end, above-mentioned convex
Point is in washer.
In combinations of the above formula input shaft, the salient point is hemispherical.
Salient point is an integral structure with locking cylinder, and salient point can effectively increase the company between locking cylinder and washer after washer
Stability is connect, is finally connected in ontology two is stable on ontology one.Rotate ontology two will not relative to ontology one.
Compared with prior art, this combined type input shaft is due to the ontology one with output end and with the ontology of input terminal
Two be split type structure, and therefore, entire input shaft structure is simple, and difficulty of processing reduces, and is assembled also easier.
Meanwhile ontology one is securely attached to together with ontology two under the action of locking cylinder, stability is also relatively high,
With very high practical value.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of this combined type input shaft.
In figure, 1, ontology one；1a, output end；1b, gear edge；2, ontology two；2a, input terminal；2b, convex shoulder；2c, attachment base；

Specific embodiment
As shown in Figure 1, this combined type input shaft, including ontology in the shape of a rod, the both ends of the ontology are respectively input terminal
2a and output end 1a, the ontology include the ontology 1 and ontology 22 in the form of annular discs in elongated rod shape, and above-mentioned input terminal 2a
In 22 side of ontology, above-mentioned output end 1a is located at one 1 outer end of ontology, passes through between one 1 inner end of ontology and ontology 22
Connection structure is connected.
One 1 inner end of ontology has the gear of protrusion along 1b, and above-mentioned ontology 22 is in the form of annular discs and 22 inside of ontology has
The convex shoulder 2b of protrusion, 22 sets of the ontology at one 1 inner end of ontology and above-mentioned gear is resisted against on convex shoulder 2b along 1b.
It further include a tubular locking cylinder 3,3 sets of above-mentioned locking cylinder is on ontology 1 and the two is threadedly coupled, the lock
Tight cylinder 3 is resisted against on above-mentioned ontology 22.
Washer 4 flexible is also cased on the ontology 1, above-mentioned washer 4 is pressed between locking cylinder 3 and ontology 22.
22 end of ontology has recessed attachment base 2c, and above-mentioned washer 4 is located at attachment base 2c and outside washer 4
Side and 22 outside flush of ontology.
The washer 4 is rubber material.According to the actual situation, it is also feasible that the washer 4, which is felt materials,.
There are the contact structures that can increase frictional resistance between the locking cylinder 3 and washer 4.
