Abstract
The utility model discloses a transmission coupling with key blocks, which comprises a transmission disk (1) and a shaft sleeve (2). Four arc-shaped keys (3) are evenly arranged in a hole on the circumference of the shaft sleeve, the transmission disk is arranged in an axial long groove (4) arranged on the circumference of the shaft sleeve, the outer arc-shaped surfaces of the arc-shaped keys are contacted with the top surface of an inner groove of the transmission disk, the end of the transmission disk is provided with an end cover (5), the end cover is connected with the transmission disk through a screw (6), and a seal ring (7) is arranged between the end cover and the shaft sleeve. The transmission coupling with the key blocks has the advantages of being capable of bearing large torque and being good in stability, high in operation reliability, simple in manufacturing process and particularly suitable for a heavy mechanical transmission structure.
Description
Technical field
The utility model relates to the coupling technical field, especially relates to a kind of key piece transmission coupling.
Background technique
In the existing technology, drum type gear coupling transmitting torque is maximum, and use more, but its not to be face contact carry-over moment ability receive certain limitation, therefore need a kind of with the face contact, the bigger and also bigger coupling of angle compensation rate allowable of torque transmission capability.
The model utility content
The purpose of the utility model is exactly in order to address the above problem, and a kind of key piece transmission coupling is provided.
To achieve these goals, the utility model adopts following technological scheme:
A kind of key piece transmission coupling is characterized in that, comprising: driving disk (1) and axle sleeve (2); Evenly be furnished with four circular arc keys (3) in the hole on the said axle sleeve circumference; Said driving disk is located in the axial elongated slot (4) on the axle sleeve circumference, and the exterior arc surface of said circular arc key contacts with inside groove end face on the driving disk, and said driving disk end is provided with end cap (5); Said end cap is connected with driving disk through screw (6), and said end cap and shaft room are provided with seal ring (7).
The beneficial effect of the utility model is: employing face contact carry-over moment, can receive bigger torque, and this coupler structure good stability, operational reliability is high, and manufacturing process is simple.
Description of drawings
Fig. 1 is a key piece transmission coupling structural representation.
Fig. 2 is an A-A sectional drawing among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration:
Like Fig. 1, shown in Figure 2, a kind of key piece transmission coupling, it comprises: driving disk 1 and axle sleeve 2; Evenly be furnished with four circular arc keys 3 in the hole on the said axle sleeve circumference; Said driving disk is located in the axial elongated slot 4 on the axle sleeve circumference, and the exterior arc surface of said circular arc key contacts with inside groove end face on the driving disk, and said driving disk end is provided with end cap 5; Said end cap is connected with driving disk through screw 6, and said end cap and shaft room are provided with seal ring 7.
The above is merely the preferred implementation of the utility model, and the protection domain of the utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to the protection domain of the utility model.For a person skilled in the art, some improvement of under the prerequisite of the principle that does not break away from the utility model, carrying out, these improve the protection domain that also should be regarded as the utility model.
