Abstract
The invention relates to an agricultural machine coupling which is cylindrical in appearance. An elongated slot (1) is formed in the axial center of the coupling, one end of the elongated slot (1) is communicated with the outer circle while the other end of the same is not communicated with the outer circle, a short slot (2) is formed in the radial center, one end of the short slot (2) is communicated with the outer circle while the other end stops at the axial center, counter via holes (3) are formed in the outer circle surface of the cylinder in the axial direction, and threaded holes (4)are formed oppositely to the counter via holes (3). The agricultural machine coupling is simple and practical in structure, and can tightly connect two shafts large in tolerance range together.
Description
Technical field
The present invention relates to a kind of farm machinery, be specifically related to a kind of farm machinery coupling.
Background technique
Farm machinery is the machinery at farmland operation, and the existing farm machinery part of China is mostly durable, and the requirement of precision aspect is not too high, and the machining tolerance scope of transmission shaft is larger, and existing coupling can not meet usage requirement.
Summary of the invention
The object of the present invention is to provide a kind of farm machinery coupling, simple and practical, two larger axles of tolerance range can be linked together securely.
The technical solution used in the present invention is: a kind of farm machinery coupling, profile is cylinder annular, in axial centre, be provided with an elongated slot 1, the logical cylindrical of one end-grain cutting of elongated slot 1, the other end is not cut logical cylindrical, is provided with a short groove 2 in radial center, the logical cylindrical of one end-grain cutting of short groove 2, the other end terminates in axial centre place, at cylinder periphery axial direction, is provided with heavy via hole 3, and its opposite is provided with tapped hole 4.
Described short groove 2 is arranged on the side that elongated slot 1 is cut logical cylindrical.
Described heavy via hole 3 and tapped hole 4 are arranged on the side that elongated slot 1 is cut logical cylindrical.
Described heavy via hole 3 and tapped hole 4 are arranged on the both sides of short groove 2 symmetrically.
The present invention compared with prior art has following beneficial effect: simple and practical, two larger axles of tolerance range can be linked together securely.
accompanying drawing explanation:
Fig. 1 is plan view of the present invention;
Fig. 2 is plan view of the present invention;
Fig. 3 is sectional view of the present invention.
embodiment:
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of farm machinery coupling, profile is cylinder annular, in axial centre, be provided with the elongated slot 1 that a width is 4mm, the logical cylindrical of one end-grain cutting of elongated slot 1, the other end is not cut logical cylindrical, in radial center, be provided with the short groove 2 that a width is 2mm, the logical cylindrical of one end-grain cutting of short groove 2, the other end terminates in axial centre place, short groove 2 is arranged on the side that elongated slot 1 is cut logical cylindrical, at cylinder periphery axial direction, be provided with the heavy via hole 3 of two Φ 13, its opposite is provided with the tapped hole 4 of two M12, heavy via hole 3 and tapped hole 4 are arranged on the side that elongated slot 1 is cut logical cylindrical, and be arranged on symmetrically the both sides of short groove 2.
