Description
Technical Field
The utility model belongs to the technical field of machinery, concretely relates to locking dish shaft coupling.
Background
The coupling is also called coupling, which is a device for connecting two shafts or a shaft and a rotating part, rotating together in the process of transmitting motion and power and not separating under normal conditions. Sometimes it is used as a safety device to prevent the coupled machine parts from bearing excessive load, and it plays the role of overload protection. The coupling is mainly used for firmly connecting a driving shaft and a driven shaft in different mechanisms to rotate together and transmitting mechanical parts of motion and torque. Sometimes also to couple shafts with other parts. Usually, the two halves are combined and fastened to the two shaft ends by a key or a tight fit, and then the two halves are connected in a certain way. The coupling can also compensate the effect of inaccurate manufacture and installation, impact alleviation, vibration absorption and the like between two shafts. Most couplers on the market have common fastening effect, are quite complex to install and disassemble, are time-consuming and labor-consuming to use, and do not meet the requirements of the society at present.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve just is not enough to above-mentioned prior art, provides a locking dish shaft coupling, and the assembly is convenient with the dismantlement, and completion that can be quick is connected between the diaxon, convenient practicality.
The utility model adopts the technical proposal that: the utility model provides a locking dish shaft coupling, includes a pair of locking endotheca and a pair of locking overcoat, the locking endotheca comprises linkage segment and toper section, the linkage segment lateral wall is evenly opened around its axis has the several connecting hole, toper section surface is equipped with the external screw thread, the locking overcoat comprises locking section and interior toper section, the locking section lateral wall is close to marginal position and evenly opens around its axis has several locking hole, interior toper section inner wall is equipped with the internal thread that matches with the external screw thread, locking endotheca and locking overcoat threaded connection.
In one embodiment, a connecting bolt is arranged in the connecting hole, and a connecting nut matched with the connecting bolt is arranged at the tail end of the connecting bolt.
In one embodiment, a locking bolt is arranged in the locking hole, and a locking nut matched with the locking bolt is arranged at the tail end of the locking bolt.
In one embodiment, the inner side wall of the locking section is provided with a slot at a position corresponding to the connecting hole.
The beneficial effects of the utility model reside in that:
1. through the double locking action of the locking inner sleeve and the locking outer sleeve, the locking inner sleeve and the two shafts can generate interference fit, so that the torque can be well transmitted, and the shaft cannot be damaged;
2. through the threaded connection of toper section and interior conic section, can slowly step reinforcing locking degree between locking endotheca and the axle, prevent to exert oneself uneven and cause the damage to the shaft coupling.

In the figure: 1. locking the inner sleeve; 2. locking the outer sleeve; 3. connecting holes; 4. a locking hole; 5. a connecting bolt; 6. a connecting nut; 7. an external thread; 8. an internal thread; 9. locking the bolt; 10. locking the nut; 11. grooving; 101. a connecting section; 102. a tapered section; 201. a locking section; 202. an inner cone section.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, 2 and 3, a locking disc coupling comprises a pair of locking inner sleeves 1 and a pair of locking outer sleeves 2, wherein each locking inner sleeve 1 comprises a connecting section 101 and a conical section 102, a plurality of connecting holes 3 are uniformly formed in the outer side wall of the connecting section 101 around the axis of the connecting section, external threads 7 are arranged on the outer surface of the conical section 102, each locking outer sleeve 2 comprises a locking section 201 and an inner conical section 202, a plurality of locking holes 4 are uniformly formed in the outer side wall of the locking section 201 close to the edge position around the axis of the locking section, internal threads 8 matched with the external threads 7 are arranged on the inner wall of the inner conical section 202, and the locking inner sleeves 1 are in threaded connection with the locking outer sleeves 2.
In this embodiment, a connecting bolt 5 is arranged in the connecting hole 3, and a connecting nut 6 matched with the connecting bolt 5 is arranged at the tail end of the connecting bolt 5.
In this embodiment, a locking bolt 9 is arranged in the locking hole 4, and a locking nut 10 matched with the locking bolt 9 is arranged at the tail end of the locking bolt 9.
In this embodiment, the inner side wall of the locking section 201 is provided with a slot 11 at a position corresponding to the connecting hole 3.
The taper of the tapered section 102 is less than the taper of the inner tapered section 202.
When the locking disc coupling is used, firstly, a locking inner sleeve 1 and a locking outer sleeve 2 are sleeved on two shafts to be connected, then the two locking inner sleeves 1 are connected by the connecting bolt 5 and the connecting nut 6 through the connecting hole 3, then the locking outer sleeve 2 is screwed into the locking inner sleeve 1 through the threaded connection of the external thread 7 and the internal thread 8, during the screwing-in process, because the taper of the tapered surface of the tapered section 102 is smaller than that of the inner tapered surface of the inner tapered section 202, therefore, the locking outer sleeve 2 generates pressure to enable the locking inner sleeve 1 to gradually press the shaft to be connected, and finally the locking inner sleeve 1 and the shaft to be connected generate interference fit, the locking inner sleeve 1 is fastened on the shaft, and finally the two locking outer sleeves are connected through the locking hole 4 by matching the locking bolt 9 with the locking nut 10 to prevent the threaded connection from loosening, so that the two shafts are connected to transmit movement and torque.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
