Abstract
The utility model discloses a tooth coupler which comprises a first inner gear ring and a second inner gear ring. A first inner tooth is arranged on the inner circle of the first inner gear ring, a second inner tooth is arranged on the inner circle of the inner gear ring, a first bolt hole and a second bolt hole are formed in the outer circle of the first inner gear ring and the outer circle of the second inner gear ring respectively, and the first bolt hole and the second bolt hole correspond in position in a one-to-one mode. An inner conical face and an outer conical face are respectively arranged at the position where the end face of the first inner gear ring and the end face of the second inner gear ring are connected, the inner conical face of the first inner gear ring and the outer conical face of the second inner gear ring are in interference fit, and the first bolt hole and the second bolt hole are respectively provided with a bolt hole sleeve. The tooth coupler can improve the transmitted torque, and be low in cost, convenient to install, and easy to maintain.
Description
Technical field
The utility model relates to a kind of coupling, more particularly relates to a kind of gear coupling, belongs to the transmission device technical field.
Background technique
Gear coupling is comprised of two ring gears at present, two ring gears are connected by inside and outside tooth with driven shaft with driving shaft respectively, driving shaft drives the internal tooth of ring gear to rotate by its external tooth, between ring gear, adopt articulation bolt to connect, the ring gear be connected with driving shaft drives the ring gear be connected with driven shaft by bolt, then the ring gear on driven shaft drives the driven shaft rotation.Because two ring gears connect by articulation bolt, when reality is used, the articulation bolt hole is is especially easily worn and torn bad, cause articulation bolt to lose efficacy to the pulling force of two ring gears, so the moment of torsion transmitted is little, need to change two ring gears after the wearing and tearing of articulation bolt hole, cost is high; By the seal ring sealing, need often to change seal ring to keep sealing between two ring gears, cost is high, operation inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of gear coupling, can improve the moment of torsion of transmission, and cost is low.
The utility model is achieved by the following technical programs:
A kind of gear coupling, comprise ring gear one, ring gear two, the inner circle of ring gear one is provided with internal tooth one, the inner circle of ring gear two is provided with internal tooth two, cylindrical at ring gear one, ring gear two is respectively equipped with bolt hole one, bolt hole two, and the position of bolt hole one, bolt hole two is corresponding one by one, the end face joint of ring gear one, ring gear two is respectively equipped with inner conical surface, male cone (strobilus masculinus), coordinating between the male cone (strobilus masculinus) of the inner conical surface of ring gear one and ring gear two is interference fit, in bolt hole one, bolt hole two, is equipped with the screw cover.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid a kind of gear coupling, be provided with tool withdrawal groove between the male cone (strobilus masculinus) of ring gear two and end face.
The interference fit of the male cone (strobilus masculinus) of the inner conical surface of the utility model by ring gear one and ring gear two guarantees its coaxality, can bear larger radial load and transmit larger moment of torsion, overload capacity is strong, and stress equalization, working stability are reliable, and the cooperation that relies on inner conical surface, male cone (strobilus masculinus) guarantees the sealing of gear coupling, do not use seal ring, reduce costs; And, at bolt hole one, the interior screw cover that arranges of bolt hole two, bolt overlaps fixedly ring gear one and ring gear two through screw, after the wearing and tearing of screw cover, only need replacing screw cover to get final product, without changing whole gear coupling; The utility model installation, easy to adjust, safeguard simple.
Advantage and disadvantage of the present utility model, will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiments, only provide as an example with reference to accompanying drawing.
The accompanying drawing explanation
Fig. 1 is the erection drawing of ring gear one of the present utility model, ring gear two;
Fig. 2 is the plan view of ring gear one of the present utility model;
Fig. 3 is the plan view of ring gear two of the present utility model;
Fig. 4 is A enlarged view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises ring gear 1, ring gear 22, as Fig. 2, shown in Fig. 3, the inner circle of ring gear 1 is provided with internal tooth 1, the inner circle of ring gear 22 is provided with internal tooth 2 24, at ring gear 1, the cylindrical of ring gear 22 is respectively equipped with bolt hole 1, bolt hole 2 23, and bolt hole 1, the position of bolt hole 2 23 is corresponding one by one, ring gear 1, the end face joint of ring gear 22 is respectively equipped with inner conical surface 11, male cone (strobilus masculinus) 21, coordinating between the inner conical surface 11 of ring gear 1 and the male cone (strobilus masculinus) 21 of ring gear 22 is interference fit, as shown in Figure 4, be provided with tool withdrawal groove 22 between the male cone (strobilus masculinus) 21 of ring gear 2 and end face, by tool withdrawal groove 22 is set, after can guaranteeing that inner conical surface 11 and male cone (strobilus masculinus) 21 are installed, the chamfering of inner conical surface 11 does not contact the root of male cone (strobilus masculinus) 21, guarantee sealing, bolt hole 1, be equipped with screw cover 3 in bolt hole 2 23, bolt passes screw cover 3 fixedly ring gear 1 and ring gear 22.
In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
