Abstract
The utility model patent discloses a kind of aluminium alloy hitch bar, including bellows, first flange, second flange, the first flange, second flange are fixedly connected with the both ends of the bellows 1 respectively, it is characterized in that, the aluminium alloy hitch bar further includes pull rod, one end of the pull rod is fixedly connected with the first flange screw, and the other end of the pull rod is fixedly connected with the second flange screw.The utility model has the advantages that the present apparatus is light-weight, installation and convenient in carrying, intensity is big, and in addition the present apparatus has the length compensation function that connection dimension enters and leaves between axis and axis.
Description
Technical field
The utility model relates to mechanical device more particularly to a kind of aluminium alloy hitch bars.
Background technique
Al-alloy products have the advantages that light-weight intensity is high, and shaft coupling is a kind of common mechanical consumptive material, for transmitting
Power between axis and axis.Existing technical usual situation lower coupler is mostly ironware, heavier-weight, and does not have length
Compensation function, it is therefore desirable to provide a kind of technical solution to solve such technical problem.
Summary of the invention
The utility model provides a kind of aluminium alloy hitch bar, and the purpose for being related to developing the present apparatus is, the present apparatus
Light-weight, installation and convenient in carrying, in addition the present apparatus has the length compensation function that connection dimension enters and leaves between axis and axis.
The utility model provides following technical proposals: a kind of aluminium alloy hitch bar, including bellows 1, first flange
2, second flange 3, the first flange 2, second flange 3 are fixedly connected with the both ends of the bellows 1 respectively, and feature exists
In, the aluminium alloy hitch bar further includes pull rod 4, and one end of the pull rod 4 is fixedly connected with 2 screw of first flange,
The other end of the pull rod 4 is fixedly connected with 3 screw of second flange, and the pull rod 4 is presented circular array column-shaped and is distributed in institute
It states around bellows 1, the number of the pull rod 4 is at least three, and the first flange 2, second flange 3 are equipped with mounting hole 5.
The utility model has the advantages that the nut is located at outermost by adopting the above technical scheme, due to place
There is the tension of elongation in compressive state this bellows 1, therefore this nut only needs to be fixed on outside that the benefit of length can be completed
Repay adjusting.Since the bellows 1 is thin-wall pipe, and it is equipped with along being surrounded by undulatory texture, therefore there is weight
Amount is light, and the high distinguishing feature of intensity can bear biggish torque compared to more traditional pipeline.It is along the axial compression simultaneously to bear
Biggish power imparts the biggish elasticity of the present apparatus.The present apparatus it is light-weight, installation and convenient in carrying, intensity is big, in addition this dress
Set the length compensation function entered and left with connection dimension between axis and axis.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of aluminium alloy hitch bar described in the utility model,
Specific embodiment
The utility model is further described below in conjunction with attached drawing and specific embodiment.
In Fig. 1: bellows 1, first flange 2, second flange 3, pull rod 4, mounting hole 5.
A kind of aluminium alloy hitch bar, including bellows 1, first flange 2, second flange 3, the first flange 2, second
Flange 3 is fixedly connected with the both ends of the bellows 1 by welding respectively, and the aluminium alloy hitch bar further includes drawing
Bar 4, one end of the pull rod 4 are fixedly connected with 2 screw of first flange, the other end of the pull rod 4 and second method
Blue 3 screws are fixedly connected, the mode which is fixedly connected are as follows: the first flange 2, second flange 3 are equipped with through-hole for institute
The both ends for stating pull rod 4 penetrate, and the pull rod 4 is equipped with external screw thread, and can be screwed on nut, as shown, the nut is located at outermost,
Due to there is the tension of elongation in this bellows of compressive state 1, this nut, which only needs to be fixed on outside, can be completed length
The compensation adjustment of degree.Since the bellows 1 is thin-wall pipe, and it is equipped with along undulatory texture is surrounded by, therefore
With light-weight, the high distinguishing feature of intensity can bear biggish torque compared to more traditional pipeline.It is along the axial compression simultaneously
Biggish power can be born, the biggish elasticity of the present apparatus is imparted.
The pull rod 4 is presented circular array column-shaped and is distributed in around the bellows 1, and the number of the pull rod 4 is at least three
Only, the first flange 2, second flange 3 are equipped with mounting hole 5.The mounting hole 5 is complete for installing corresponding axis, transmission shaft
At docking.
