Abstract
The utility model is a kind of major axis carry-over moment structure, comprise large pull bar and gearbox, large pull bar is connected with gearbox, first main shaft and the second main shaft are installed in large pull bar, first main shaft is connected by shaft coupling with the second main shaft, in the first main shaft, lower link bar is installed, in the second main shaft, push rod is installed, second main shaft one end is provided with belt pulley, belt pulley is connected with the Timing Belt of gearbox, lower link bar and push rod center all offer the gas hole communicated, and are provided with bearing between large pull bar and the first main shaft and the second main shaft.The utility model main shaft is divided into the first main shaft and the second main shaft, just reduces the length of single main shaft, this reduces the difficulty of processing of main shaft, and the machining accuracy of main shaft can be protected.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of major axis carry-over moment structure.
Background technology
At present, in mechanical transmission course, speed changer is rotated by Timing Belt drive shaft, carry-over moment, because main shaft is very long, center is opened to be needed to offer gas hole, and requirement on machining accuracy is a lot, cause the process technology difficulty of long main shaft large, machining accuracy is low, dynamic balancing and static balance poor.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of major axis carry-over moment structure, to solve the problem that long spindle processing precision is low and process technology difficulty is large.
On the one hand, the utility model provides a kind of major axis carry-over moment structure, comprise large pull bar and gearbox, large pull bar is connected with gearbox, first main shaft and the second main shaft are installed in large pull bar, first main shaft is connected by shaft coupling with the second main shaft, in the first main shaft, lower link bar is installed, in the second main shaft, push rod is installed, second main shaft one end is provided with belt pulley, belt pulley is connected with the Timing Belt of gearbox, lower link bar and push rod center all offer the gas hole communicated, and are provided with bearing between large pull bar and the first main shaft and the second main shaft.
Shaft coupling is without backlash yielding coupling, and without backlash yielding coupling by the first connector and the second connector and elastic buffering pad, the first connector and the second connector profile of tooth coordinate, and elastic buffering pad is between the first connector and the second connector.
A kind of major axis carry-over moment structure that the utility model provides, long main shaft is divided into the first main shaft and the second main shaft, reduce the length of single main shaft, this reduces the difficulty of processing of main shaft, the machining accuracy of main shaft can be protected, they are connected without backlash yielding coupling by one, can axially install easily.The transmission without backlash is ensure that under the effect of pre-tight stress.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the utility model major axis carry-over moment structural representation.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, the preferred a kind of major axis carry-over moment structure of the utility model, comprise large pull bar 2 and gearbox 8, large pull bar 2 is connected with gearbox 8, first main shaft 1 and the second main shaft 5 is installed in large pull bar 2, first main shaft 1 is connected by shaft coupling 4 with the second main shaft 5, shaft coupling 4 preferably adopts without backlash yielding coupling 4, without backlash yielding coupling 4 by the first connector and the second connector and elastic buffering pad, first connector and the second connector profile of tooth coordinate, and elastic buffering pad is between the first connector and the second connector.Can axially install easily.The transmission without backlash is ensure that under the effect of pre-tight stress.
In the first main shaft 1, lower link bar 3 is installed, in the second main shaft 5, push rod 6 is installed, second main shaft 5 one end is provided with belt pulley 7, belt pulley 7 is connected with the Timing Belt 9 of gearbox 8, lower link bar 3 and push rod 6 center all offer the gas hole communicated, and are provided with bearing between large pull bar 2 and the first main shaft 1 and the second main shaft 5.
Power drives belt pulley 7 to drive the second main shaft 5 to rotate through the Timing Belt 9 of gearbox 8, and moment passes to the first main shaft 1 synchronous axial system through shaft coupling 4, blows and spread out of through push rod 6 and pull bar in center.
A kind of major axis carry-over moment structure that the utility model provides, long main shaft is divided into the first main shaft 1 and the second main shaft 5, reduce the length of single main shaft, this reduces the difficulty of processing of main shaft, the machining accuracy of main shaft can be protected, they are connected without backlash yielding coupling 4 by one, can axially install easily.The transmission without backlash is ensure that under the effect of pre-tight stress.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
