Description

A power train coupling

The present invention relates to a power transmission coupling, and more particularly to a strong torsional rigidity and flexibility, speed and accuracy, high efficiency and long life, and easy assembly and maintenance unnecessary, in particular partial replacement and stress distribution effect This greatly improves the quality and reliability of the product so that consumers can plant a good image.

As is well known, the coupling (coupling) used to connect the shaft and the shaft to transmit power is to combine the driving shaft and the rotating shaft at both ends to transmit the rotational force, thereby reducing the impact or noise generated during forward / reverse rotation. Various couplings such as disc type, bellows type, and slit type have been developed and used. These various types of coupling mainly absorb the impact by using the elasticity of the metal material, when the high-speed rotation is formed a frequency that causes resonance, the coupling causes severe resonance, as well as causing a large noise in the work space, Due to this, vibration is transmitted to the entire system of the automated machine, causing problems in performance and durability, and there are many problems in that positioning cannot be performed in a short time.

On the other hand, the coupling (coupling) is to connect the two shafts and serves to transfer power, unlike the clutch will not be able to separate the connection unless disassembled. In particular, it is also referred to as shaft coefficient and coupling, and there are various types of shaft joints, and each has different characteristics. When designing, the most suitable type for the machine should be selected in consideration of the structure of the shaft joint, the method of fixing with the shaft, the allowable torque and the allowable rotation speed.

In order to solve the above problem, conventionally disclosed Patent Publication No. 2001-0068135 (Application No. 2001-0022704) (name: coupling) has been filed. That is, the conventional technique described above is mounted at the ends of the drive shaft 5 and the driven shaft 7 as shown in Figs. 1 (a) (b) (c) and protrudes in a direction facing each other alternately. A pair of connecting blocks 15 having a locking jaw 20 to be coupled with each other, and a pair of buffering blocks 35 positioned between the pair of connecting blocks 15 and interposed between adjacent locking jaws 20 are provided. In the coupling including the shock absorbing member 30, the locking jaw 20 of at least one side of the locking jaw 20 of the connection block 15 is detachably attached to the radially outer side of the connection block 15. Is installed and configured, when the locking jaw 20 is separated from the connection block 15, so that the buffer member 30 interposed between the pair of connection blocks 15 can be easily removed or inserted A coupling is provided, which is characterized by the above. The coupling configured as described above is composed of a pair of connecting blocks 15 respectively coupled to the drive shaft 5 and the driven shaft 7, and a buffer member 30 interposed between the connecting blocks 15. In addition, the connecting block 15 has a pair of through holes 17 formed in the center thereof, and the through holes 17 have a pair of key grooves 18 corresponding to the keys 16 of the shafts 5 and 7. Blocks 15 are mounted on the ends of the drive shaft 5 and the driven shaft 7, respectively, the plurality of locking projections 20 protruding in a direction facing each other are alternately coupled and rotated at the same time drive shaft 5 The rotational power of) is transmitted to the driven shaft (7). In particular, the locking jaws 20 adjacent to each other of the locking jaws 20 of the connecting block 15 is detachably coupled to the radially outer side of the connecting block 15 by the bolt (22). Thus, when the locking jaw 20 detachably coupled to the connection block 15 is released to the outer side in the radial direction of the connection block 15 by releasing the bolt 22, the space outside the connection block 15 It is provided so that the buffer member 30 can be easily removed and inserted through this space. In addition, the buffer member 30 is a plurality of buffers interposed between the ring body 32 is inserted between the pair of connecting blocks 15 and the engaging jaw 20 adjacent to each other in the circumference of the ring body 32 A plurality of wings 35 are provided at predetermined intervals. The shock absorbing member 30 prevents the engaging jaw 20 alternately coupled to each other when the driven shaft 7 is rotated by the drive shaft 5 to directly absorb each other, thereby absorbing the impact force. To prevent damage. The shock absorbing member 30 is easily detached or inserted into the connection block 15 when the locking jaw 20 detachably coupled to the connection block 15 is separated out in the radial direction of the connection block 15. I can put it. Therefore, the coupling is different from the conventional one in which the drive motor fixed to the bottom or the mechanical device driven by the drive motor has to be removed and the shock absorbing member 30 needs to be replaced. Since the shock absorbing member 20 can be easily removed or inserted from the connection block 15 by separating the locking jaw 20, the replacement installation work of the shock absorbing member 30 is very easy. In addition, since the coupling is to pull out the shock absorbing member 30 to the outside of the connection block 15 or to the outside of the connection block 15, there is no need to remove the mechanical device and reinstall, so the working time is Significantly reduced, such as work efficiency can be improved. However, the above-described prior art also has many problems as follows. That is, if any part of the prior art cushioning member is broken, a big problem arises in that the whole must be replaced. In addition, the prior art has a big problem that the torsional flexibility is low because the four feet of the cushioning member overlaps the locking jaw of the connection block. In addition, the above-mentioned prior art also has a problem that it is impossible to disperse the stress when bent structurally.

The present invention has been made in order to solve the above problems of the prior art, the first object is provided with a pair of shaft joint member and a cylindrical spider, the second of the present invention by the above technical configuration The purpose is to have strong torsional rigidity and flexibility, the third purpose is to have speed and accuracy, the fourth purpose is to have high efficiency and long life, and the fifth purpose is easy assembly and maintenance unnecessary. In particular, the sixth purpose is that it can be partially replaced, and the seventh purpose is to provide the effect of dispersing the stress, and the eighth purpose is to greatly improve the quality and reliability of the product, thereby providing a good image for consumers. It provides a power transmission coupling for planting.

In order to achieve the above object, the present invention provides a pair of shaft joint members having a shaft coupled to the outer coupling hole and protruding a plurality of ribs at a predetermined interval on the inner side thereof, and bending and cushioning between the ribs. It provides a power transmission coupling characterized in that a plurality of cylindrical spiders that serve to be assembled.
