Description
Technical field:
The utility model relates to torque axis field, in particular to a kind of coalcutter torque axis for being convenient for operation.
Background technique:
Torque axis is the main connector of coalcutter motor and cutterhead transmitting mechanical energy, and coalcutter use environment is special,
Design coalcutter motor is required according to user, as shown in Fig. 1, existing torque axis 8 is passed through the existing shaft 9 of coalcutter motor 10
Interior, existing shaft and existing torque axis spline junction are A, and existing torque axis 8 designs as shown in Fig. 2, coalcutter motor 10
It is to be of coupled connections by existing 9 internal spline of shaft and existing 8 external splines of torque axis, when not needing work, as shown in Fig. 3,
9 internal spline of existing shaft of existing 8 external splines of torque axis and coalcutter motor 10 is separated, i.e., existing 8 external splines of torque axis with
Existing 9 internal spline of shaft separates, and existing 9 internal spline of shaft supports existing torque axis 8 seldom a part after separating, and does not exist
Center, the head of existing torque axis 8 is heavier at this time, just will appear and droops a phenomenon, when existing 9 internal spline of shaft need with
When existing 8 external splines of torque axis needs work to connect, cause existing torque axis 8 that can not normally be of coupled connections with existing shaft 9.It is existing
When having torque axis 8 and existing 9 pull-off of shaft or being of coupled connections, existing torque axis 8 can be pushed away in axially pumping, at this moment will appear gas resistance
Hinder, as inflator is the same, causes using difficulty.
Summary of the invention:
In view of this, it is necessary to provide a kind of torque axis convenient for operation.
A kind of torque axis convenient for operation, including hollow shaft body, involute outer spline portion, compensating groove, supporting table and axis
To air ventilation road, the both ends of hollow shaft body are arranged for being fitted in involute outer spline portion with coalcutter motor internal spline,
Compensating groove is set in hollow shaft body, and compensating groove is located at coalcutter motor shaft end, and one end of hollow shaft body is equipped with supporting table, empty
Several axial air ventilation roads are opened up on spindle body.
Preferably, equipped place's mounting O-shaped sealing ring of hollow shaft body and supporting table.
Preferably, supporting table and hollow shaft body are integrally formed.
The utility model increases supporting table, axial air ventilation road and O-ring seal, solution on the basis of torque axle construction
Certainly torque axis droops head and inflator phenomenon in use, and shockproof, and staff is easy to use in use.
Power output shaft of the torque axis as cutting motor, plays transmit between cutting motor and transmission system first
The effect of torque, secondly when winning machine cutting part is in most bad working environments because of heavy overload, torque axis can be concentrated in stress
Place's fracture, to play the role of protecting transmission system.
Detailed description of the invention:
It, below will be to use required in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
Attached drawing be briefly described, it should be understood that the following drawings illustrates only some embodiments of the utility model, therefore should not be by

Specific embodiment:
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Usually here in attached drawing description and
The component of the utility model embodiment shown can be arranged and be designed with a variety of different configurations.
Therefore, requirement is not intended to limit to the detailed description of the embodiments of the present invention provided in the accompanying drawings below
The scope of the utility model of protection, but it is merely representative of the selected embodiment of the utility model.Based in the utility model
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the range of the utility model protection.
The utility model provides embodiment in detail below.
Please refer to Fig. 4 and Fig. 5, the torque axis convenient for operation includes hollow shaft body 1, involute outer spline portion 2, unloads
Lotus slot 3, supporting table 4 and axial air ventilation road 5, the both ends setting of hollow shaft body 1 in coalcutter machine shaft 6 for spending
Key is fitted in involute outer spline portion 2, compensating groove 3 is arranged in hollow shaft body 1, compensating groove 3 is located at coalcutter machine shaft 6
Shaft end, one end of hollow shaft body 1 are equipped with supporting table 4, and several axial air ventilation roads 5 are opened up in hollow shaft body 1.Torque axis
As the power output shaft of cutting motor, play the role of transmitting torque between cutting motor and transmission system first,
It is secondary when winning machine cutting part is in most bad working environments because of heavy overload, torque axis can be broken at compensating groove 3, compensating groove 3
For stress concentrate place, thus play the role of protect coalcutter motor transmission system.Hollow shaft body 1 and supporting table 4
Equipped place's mounting O-shaped sealing ring 7.The design of O-ring seal 7 has certain anti seismic efficiency.Supporting table 4 and hollow shaft body 1
It is integrally formed.
