Description
Technical field
The utility model relates to a kind of general utility tool that increases torsion, and especially being used for the planetary gear of detaching tyre nut at automobile maintenance industry increases spanner.
Background technology
The moment of torsion that general spanner produces in use is by arm of force length and externally applied forces decision.For the spanner of certain specification, its arm of force length is fixed, and increases the arm of force even add sleeve pipe, and its length also can not be oversize, and general length overall is 2～3 times of spanner arm of force length.In use, it is not enough to occur moment of torsion sometimes, tears not lower nut open, this situation will occur during such as automobile re-type dismounting nut.
Summary of the invention
The purpose of this utility model is: a kind of planetary gear reinforcement spanner is provided, produces very big moment of torsion with less power, overcome the use defective of common wrench in some industry, reach quick laborsaving dismounting.
The technical scheme that its technical problem that solves the utility model adopts is: this spanner is made up of main body and handle, handle is installed in the whole spanner of forming on the main body, described main body is made up of cover cylinder shell and many group planetary gears, the sleeve inner walls is established internal tooth, the series connection of many group planetary gears is installed in the cover cylinder shell, described every group of planetary gear is made up of the planetary gear of a centre wheel and three engagement centre wheels that are symmetrically distributed, the internal tooth of planetary gear mesh sleeve inner walls, one side of three planetary gears is installed planet carrier, the opposite side of three planetary gears connects next by bearing pin and organizes planetary centre wheel, connect handle by power shaft on first group of planetary centre wheel, last organizes planetary bearing pin is output shaft.
In the planetary gear reinforcement spanner of the present utility model, organize planetary gear more and be installed in the cover cylinder shell with spring flange and packing ring by the hole.
In the planetary gear reinforcement spanner of the present utility model, outside the cover cylinder shell, assist handle is installed.
During use, select sleeve-type coupling to be installed in the output axle head according to the nut specification, sleeve-type coupling is enclosed within on the nut that will dismantle, and cover cylinder shell afterbody is put into the spoke hole of tire, and one holds and produces other strength when assist handle guarantees to rotate the cover cylinder shell is not rotated; Pull handle when the another hand and make power shaft when rotation, power shaft just can rotate first group of planetary centre wheel, this centre wheel engagement planetary gear, this planetary gear rotation is organized the power of planetary centre wheel as next, like this, motion just hands on successively, and in the end one group of planetary output axle head produces trace rotation and very big moment of torsion, easily unclamps nut; After unclamping nut, can change the common wrench dismounting.
The utility model is simple and compact for structure, and is easy to use, laborsaving fast, is particularly useful for automobile maintenance industry.
