Abstract
The utility model relates to a torque conversion extension tooth-like spanner belongs to the hand tool field. The transmission device comprises a gear box, driving gear shafts and driven gear shafts, wherein the driving gear shafts arranged on the left side and the right side of the gear box are meshed with the driven gear shafts through N transmission gear shafts arranged in the middle of the gear box to transmit power, the driving gear shafts are connected with rotating sleeve handles, and the driven gear shafts are connected with nut sleeves. The utility model discloses utilize the gear drive principle design, adjust the centre-to-centre spacing of driving gear axle and driven gear shaft through the quantity of increase and decrease driving gear axle to the output torque of spanner is adjusted to the operation length of adjustment spanner through the tooth ratio of adjustment driving gear axle and driven gear shaft, and furthest reduces workman's intensity of labour, improves work efficiency.
Description
Technical Field
The utility model belongs to the hand tool field, specifically speaking are tooth-like spanner of torque conversion extension.
Background
Along with the rapid development of scientific technology, the labor cost and the production cost are continuously increased, the land price is continuously increased, so that the land is in the order of magnitude, the space for installing equipment on a factory production line for saving land is compressed to the limit, the assembling and disassembling space of connecting and fastening bolts of the equipment is very small, the maintenance and the overhaul are very inconvenient, most of the existing bolt assembling and disassembling tools cannot be normally used in the narrow space, and a small number of bolt assembling and disassembling tools cannot be freely applied during the operation although the existing bolt assembling and disassembling tools can be used only marginally, so that the working efficiency is very low.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a torque-variable extension tooth type wrench,
the wrench is designed by utilizing a gear transmission principle, has the advantages of simple structure, convenience in use and safety in work, can adjust the operation length and the output torque of the wrench according to the field requirement, reduces the labor intensity of workers to the maximum extent and improves the working efficiency.
The utility model provides a technical scheme that its technical problem adopted is: the torque-converting extension tooth-type wrench is characterized in that driving gear shafts arranged on the left side and the right side of the gear box and driven gear shafts are meshed with each other through N transmission gear shafts arranged in the middle of the gear box to transmit power, a rotating sleeve handle is connected with the driving gear shafts, nut sleeves are connected with the driven gear shafts, and the number N of the transmission gear shafts is larger than or equal to 1.
The utility model discloses still can realize through following measure: the driving gear shaft and the driven gear shaft are connected by a synchronous toothed belt to transmit power. The driving gear shaft and the driven gear shaft are connected by a chain to transmit power.
The beneficial effects of the utility model are that, utilize gear drive principle design, adjust the centre-to-centre spacing between drive gear axle and the driven gear axle through the quantity of increase and decrease drive gear axle to the output torque of spanner is adjusted through adjusting the number of teeth ratio of drive gear axle and driven gear axle to the operation length of adjustment spanner, and furthest reduces workman's intensity of labour and improves work efficiency.
Drawings
Fig. 1 is a schematic view of the structure principle of the present invention.
In the figure, 1 is a rotating sleeve handle, 2 is a driving gear shaft, 3 is a transmission gear shaft, 4 is a gear box, 5 is a driven gear shaft, and 6 is a nut sleeve.
Detailed Description
The utility model discloses a gear box 4, driving gear shaft 2, driven gear shaft 5, driving gear shaft 2 and driven gear shaft 5 of the 4 left and right sides installation of gear box transmit power through 3 intermeshing of N drive gear axle of 4 mid-mounting of gear box, driving gear shaft 2 is connected with rotation sleeve handle 1, driven gear shaft 5 is connected with nut sleeve 6, 3 quantity N more than or equal to 1 of drive gear axle between driving gear shaft 2 and the driven gear shaft 5, driving gear shaft 2 is connected transmission power with 5 synchronous tooth form belts of driven gear shaft, driving gear shaft 2 also can be replaced into the chain with driven gear shaft 5 and is connected transmission power.
When the utility model is used, according to the space size of an operation site, the installation positions of the driving gear shaft 2 and the driven gear shaft 5 on the bearing seat of the gear box 5 are adjusted, the center distance of the driving gear shaft 2 and the driven gear shaft 5 meets the length requirement of wrench operation, the mutually meshed driving gear shaft 3 is installed between the driving gear shaft and the driven gear shaft, the nut sleeve 6 with corresponding specification and model is installed on the driven gear shaft 5 according to the specification and model of the bolt to be disassembled and assembled, the polygonal inner hole of the nut sleeve 6 is sleeved on the nut or nut to be disassembled and assembled, one of manual or electric driving modes is selected to rotate the rotating sleeve handle 1, the driving gear shaft 2 drives the driven gear shaft 5 to rotate through the mutually meshed driving gear shaft 3, the nut sleeve 6 drives the nut or the nut to rotate and finally disassemble or fasten the nut, in addition, the gear ratio of the, the input and output torque can be changed, and the purposes of saving labor, reducing labor intensity and improving labor productivity are achieved.
