Abstract
The utility model relates to a multiple power spanner, an external tooth is arranged at the inner end of an initial momentum axis and is engaged with a drive gear which is installed on a planetary gear. The drive gear is engaged with an inner tooth of a barrel body at the same time, and the barrel body is fixedly connected with a positioning cross bar. An external tooth is also arranged at the inner end of a planetary gear carrier and is engaged with the next drive gear of the planetary gear carrier. The inner end of the last step planetary gear carrier and the sleeve barrel drive axis are made into a whole or the planetary gear carrier is fixedly connected with the sleeve barrel drive axis. A planetary gear speed reducing mechanism of the utility model is connected by multi-step tooth carriers in series, and the utility model can realize multiplication of each single section reinforcement and large torsional force accommodation range. The utility model is not only capable of disassembling and assembling a vehicle tyre easily, but also capable of being used in large electromechanical device manufacture and maintenance industry.
Description
Technical field:
The utility model relates to machine tool, particularly used socket wrench during dismounting tire fastener.
Background technology:
In order to guarantee vehicle driving safety, the bolt and nut on the tire must have enough tautnesses.For ease of vehicle-mounted and convenient use, the reinforcement spanner of planetary gear speed-reduction has appearred in the prior art, and its inwall is shaped on straight internal tooth, initiating axle and the transmission gear engagement that is installed on the tooth rest, transmission gear and tube internal gearing.Because cylindrical shell is fixed, then the rotation of transmission gear drives planetary gear carrier and drives the sleeve drive shaft turns then.But it is still enough not big that one of defective of this structure is the reinforcement multiple, and the occasion of not competent special tautness is used sometimes.
Summary of the invention:
The purpose of this utility model provides a kind of Multiple power spanner that can obviously increase torsional forces and be convenient for carrying and use.
The technical solution of the utility model is: initiating axle the inner is shaped on external tooth, and with the transmission gear engagement that is installed on the planetary gear carrier, gear while and cylindrical shell internal gearing, cylindrical shell is connected with the location cross bar, it is characterized in that planetary gear carrier the inner also is shaped on external tooth, with the transmission gear engagement on the next stage planetary gear carrier, planetary gear carrier the inner of the last grade is made one with the sleeve axle drive shaft or is connected.Transmission gear on the two-stage planet gear meshed frame all with the internal gearing of same cylindrical shell (3).2～4 transmission gears are installed on every grade of planetary gear carrier.
Planetary gear reducing mechanism of the present utility model can be realized multiplying each other of every single-unit reinforcement by multi-stage gear frame serial connection, and the torsional forces applicable area is big, except the light fastening tyre of vehicle wheels of energy, also may be used on the manufacturing and the maintenance industry of giant mechanical and electrical equipment.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the front view of planetary gear carrier 9 among Fig. 1.
Fig. 3 is Fig. 2 A-A schematic cross-section.
The specific embodiment:
With reference to Fig. 1, application of force axle is that straight-tooth gear is made in initiating axle 10 the inners, and extend in the planetary gear carrier 9.Planetary gear carrier 9 relative eccentric positions are opened axial hole, and each installs transmission gear 8 and wheel shaft thereof 7, two transmission gears 8 and the engagement of initiating shaft end gear, as Fig. 2, shown in Figure 3, simultaneously its outside each with the straight-tooth engagement of cylindrical shell 3 inwalls.Because cylindrical shell 3 connects with fixed cross bar 1 weldering in use,, the rotation of transmission gear 8 does the planet rotation around main shaft 2 so driving planetary reduction gear frame 9.For the moment of torsion that doubles, also make and the identical straight-tooth of initiating axle head shape the inner of planetary gear carrier 9, and extend into secondary planetary gear frame 9 ' in.Planetary gear carrier 9 ' shape is similar to one-level, its symmetry that different is installed 4 transmission gears 8 ' and axle 7 ', it is inner makes one with sleeve axle drive shaft 6.So the rotation of planetary gear carrier 9, by transmission gear 8 ' with cylindrical shell 3 internal gearing deceleration transmission, drive the rotation of planetary gear carrier 9 ' deceleration force amplifier, thereby initial torque amplified at double.
Other description of symbols among the figure: 4-spring, 5-steel ball, 11-lining, 12-end cap, 13-spring, 14-go into power sleeve, 15-safety cock, 18-sleeve.
