Abstract
The utility model discloses a kind of large-scale speed reducer coupling, to solve the connective stability letter problem to be improved between speed reducer and coupling in prior art.Comprise the input shaft for being connected with speed reducer, input shaft end is provided with interior hexagonal hole, and the corner of interior hexagonal hole is fillet, and interior hexagonal hole is for being connected with hexagonal output shaft on speed reducer.The advantage of this scheme is can bear compared with high pulling torque, and the unexpected impact that equipment is suffered also has certain defensive ability/resistance ability.
Description
Technical field
The utility model relates to a kind of speed reducer.
Background technique
Industrial speed reducer is divided into two classes according to the size of tooth face hardness conventionally, i.e. reducer with hardened tooth surface and soft flank of tooth retarder.And reducer with hardened tooth surface is because the advantages such as its transmission efficiency is high, compact structure, volume is little, lightweight, fault is few, smooth running are widely used in all trades and professions.Wherein at rivers, adopt in sand ship equipment, retarder is as its core component, and type selecting is with regard to particular importance.The working load of adopting sand ship equipment is quite big, connective stability between speed reducer and coupling is had to higher requirement, and owing to being zero substantially to the understanding in riverbed in digging husky process, the large-scale stone in river bed etc. easily cause the fault of equipment to the unexpected impact of retarder.
Model utility content
The utility model is intended to provide a kind of large-scale speed reducer coupling, to solve the connective stability letter problem to be improved between speed reducer and coupling in prior art.
Patent scheme: the large-scale speed reducer coupling in this programme, comprise the input shaft for being connected with speed reducer, it is characterized in that: input shaft end is provided with interior hexagonal hole, the corner of interior hexagonal hole is fillet, and interior hexagonal hole is for being connected with hexagonal output shaft on speed reducer.The advantage of this scheme is can bear compared with high pulling torque, and the unexpected impact that equipment is suffered also has certain defensive ability/resistance ability.
Further, the input shaft in coupling is connected with internal gear, and internal gear and external gear engagement, be crowned teeth on internal gear, and the angle of yaw of crowned teeth is less than 1.5 °.
The feature of technique scheme is: can bear larger torque and impulsive load, and when identical angular displacement, higher than the bearing capacity of straight-tooth coupling, be specially adapted to large-scalely adopt sand ship, and be easy to install.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's schematic diagram.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference character in Figure of description comprises: the input shaft 1 of coupling, the output shaft 2 of speed reducer.
Embodiment part is as shown in Figure 1: coupling input shaft 1 end is provided with interior hexagonal hole, and the corner of interior hexagonal hole is fillet, and interior hexagonal hole is for being connected with hexagonal output shaft 2 on speed reducer.
In coupling, be provided with the ring gear and the external gear that are meshed, external gear is crowned teeth, and the maximum deflection angle of crowned teeth is 1.5 °.Ring gear and external gear are fixed by dismountable pin of wearing.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of the utility model structure, can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.The protection domain that the application requires should be as the criterion with the content of its claim, the content that the embodiment in specification and accompanying drawing can require for power of interpretation profit.
