Abstract
Disclosed is a coupling for a tap switch. A sleeve (21) is arranged at one end of a coupling body, at least one pair of open slots (22) is arranged on the sleeve (21) of the coupling body and on the circumference of the sleeve (21) in 180-degree distribution form, the other end of the coupling body is provided with a pin hole (23), one end of the coupling body is connected with an input shaft through pins and the open slots (22), the other end of the coupling body is connected with an output shaft by a pin and the pin hole (23), the four open slots (22) are distributed uniformly on the circumference of the sleeve (21), a groove (24) is arranged between the sleeve (21) and the pin hole (23) of the coupling body, and a silencer ring is arranged in the groove (24) of the coupling body. Therefore, the coupling is more convenient to maintain.
Description
One, technical field
The utility model relates to a kind of shaft coupling that is used for shunting switch, especially a kind of shaft coupling that is applicable to the shunting switch of high-power transformer.
Two, background technology
Transformer is in running, need carry out pressure regulation to transformer, therefore shunting switch is an important components in the transformer, motor drives the shunting switch motion by shaft coupling, shaft coupling is a vitals of realizing the shunting switch motion, in existing shunting switch, usually the insulation against ground axle with shaft coupling and switch core top links together by bolt, in shunting switch generation mechanical breakdown, cause shaft coupling fracture after, need open skull, hang out the switch core maintenance, change, make the maintenance trouble.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model provides a kind of shaft coupling that is used for shunting switch, keeps in repair more convenient.
For achieving the above object, the technical scheme that the utility model is taked is: the end at the shaft coupling body is set to sleeve, the sleeve of shaft coupling body is provided with open slot, open slot is set at least one pair of and is set to into 180 ° of angles be distributed on the circumference of sleeve, the other end at the shaft coupling body is provided with pin-and-hole, one end of shaft coupling body is set to connect with power shaft by bearing pin and open slot, and the other end of shaft coupling body is set to connect with output shaft by bearing pin and pin-and-hole.
Shaft coupling body one end is connected with the output shaft of motor by open slot, shaft coupling body one end by bearing pin and propeller shaft couplings, by motor driven power transmission shaft and gear mechanism motion, thereby is made the shunting switch motion, realize the handover operation of switch.Because the shaft coupling body of design is that plug-in type connects with power transmission shaft, is arranged on the outside of switch, when carrying out the shaft coupling maintenance, do not need to open skull again, hang out fuse, directly, therefore keep in repair more convenient in motor drive mechanism and the education maintenance of gear box junction.
The utility model has designed, and open slot is set to four and be set to be evenly distributed on the circumference of sleeve.
The utility model has designed, and is provided with groove between sleeve on the shaft coupling body and jack, is provided with the noise reduction circle in the groove of shaft coupling body.
Four, description of drawings
Accompanying drawing is a schematic diagram of the present utility model.
Five, embodiment
Accompanying drawing is an embodiment of the present utility model, specify present embodiment in conjunction with the accompanying drawings, end at the shaft coupling body is set to sleeve 21, the sleeve 21 of shaft coupling body is provided with open slot 22, open slot 22 is set to four and be set to be evenly distributed on the circumference of sleeve 21, the other end at the shaft coupling body is provided with pin-and-hole 23, one end of shaft coupling body is set to connect with power shaft by bearing pin and open slot 22, the other end of shaft coupling body is set to connect with output shaft by bearing pin and pin-and-hole 23, between sleeve on the shaft coupling body 21 and pin-and-hole 23, be provided with groove 24, in the groove 24 of shaft coupling body, be provided with the noise reduction circle.
Shaft coupling body one end is connected with the output shaft of motor drive mechanism by bearing pin, shaft coupling body one end is connected with gear box by bearing pin,, thereby make the shunting switch action by motor drive mechanism driven gear case.
The characteristics of the utlity model has down:
1, owing to designed plug-in type between shaft coupling body and the connecting axle in the utility model and connected, and be installed in the shunting switch outside, make easy for installation, simultaneously when carrying out the shaft coupling maintenance, do not need to open skull again, hang out fuse, directly, make maintenance more convenient in motor and the education maintenance of gear train junction.
2,, make between shaft coupling and the body transmission more reasonable, the useful life of having improved shaft coupling because the utility model has changed existing bolt type connects and the installation site.
In being used for the shaft coupling technical field of shunting switch; Every end that includes at the shaft coupling body is set to sleeve 21; the sleeve 21 of shaft coupling body is provided with open slot 22; open slot 22 is set at least one pair of and is set to into 180 ° of angles be distributed on the circumference of sleeve 21; the other end at the shaft coupling body is provided with pin-and-hole 23; one end of shaft coupling body is set to connect with power shaft by bearing pin and open slot 22, and the technology contents that the other end of shaft coupling body is set to connect with output shaft by bearing pin and pin-and-hole 23 is all in protection range of the present utility model.
