Abstract
The utility model relates to a booster for a socket wrench, comprising a casing with a front and a back end caps, a driving shaft and an output shaft which are arranged in the casing, wherein, the front end of the driving shaft is arranged in a shaft hole at the back end of he output shaft, a planetary wheel of a planetary transmission device is arranged at the eccentric shaft part of the driving shaft, an internal tooth jacket is fixed on the casing, the planetary wheel and the output shaft are transitionally connected through a crosshead shoe. The utility model has the advantages of compact structure, small size, light weight, easy carrying, and large output torque which is beneficial for improving the efficiency of maintenance.
Description
The utility model relates to a kind of automobile-use maintenance tool, and particularly a kind of detachable lashing force is than the box spanner booster of big or corrosion securing member.
At present, car mechanic's tool box spanner tool set mainly contains spanner, extension bar and sleeve.Though these instruments are furnished with the sleeve of different size,,,, just be difficult to dismounting as bolt, nut etc. so when construction operation, run into the securing member of lashing force than big or corrosion because of the length of the spanner arm of force is certain.Generally often adopt aid in this case, the sleeve pipe etc. that for example extends is helped dismounting with the way of the lengthening spanner arm of force.During operation in the open air, just can't dismantle if can not find long sleeve pipe.
The purpose of this utility model provides a kind of box spanner booster, and its compact conformation, volume are little, in light weight, are easy to carry about with one, and its output torque is big, helps improving maintenance efficiency.
The purpose of this utility model is achieved in that this device comprises the housing that has front and rear cover and assembles its interior driving shaft and output shaft, wherein the driving shaft leading section is assembled in the rear end axis hole of output shaft, the planetary gear set of planetary driving device is contained in the eccentric axial portion of driving shaft, interior gear cover is installed on the housing, is connected by the sliding transition of determining of cross between planetary gear and output shaft.
Because the planetary driving device that the utility model adopts the small Tooth Number Difference Planetary Transmission structure to form, its planetary gear set is contained in the eccentric axial portion of driving shaft, and make between planetary gear and output shaft and be connected by the crosshead shoe transition, so when driving shaft rotates, planetary gear on the driving shaft eccentric axial portion is meshed with the tooth of interior gear cover on being packed in housing, planetary gear rotates under eccentric shaft drives, meanwhile, certainly power is passed to output shaft by cross is sliding, reaching the purpose that slow down to increase torsion, thus be easy to dismantle lashing force bigger or casting lose securing member.Because of adopting planetary driving device and be shaft coupling, so compact conformation, volume are little, in light weight with the crosshead shoe.Not only make easily, reduce manufacturing cost, and easy to use, help improving maintenance efficiency.Therefore, the utility model is very easily applied.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of concrete structure schematic diagram of the utility model.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
Describe concrete structure of the present utility model in detail according to Fig. 1-2.This device comprises housing 10, utilize rear end cap 2 on sealing gasket and bolt 4 assemble case 10, utilize the parts such as drive end bearing bracket 12, driving shaft 1, output shaft 15, planetary driving device and crosshead shoe 9 on sealing gasket and bolt 11 assemble case 10.Wherein driving shaft 1 rear end is assembled in the axis hole of rear end cap 2 by bearing 3.Driving shaft 1 front end is assembled in the rear end axis hole of output shaft 15 by bearing 14.Output shaft 15 is assembled in the axis hole of drive end bearing bracket 12 by bearing 13.The middle part of driving shaft 1 is processed with eccentric shaft.Planetary driving device adopts involute-type small Tooth Number Difference Planetary Transmission structure.Its mainly by utilize bearing 5 to be assembled in the planetary gear 8 of driving shaft 1 eccentric axial portion, the interior gear cover 7 that utilizes screw 6 to be packed on the housing 10 constitutes.The projection of the colored groove plug-in mounting crosshead shoe 9 of planetary gear 8 front ends, crosshead shoe 9 other end projections are inserted in the colored groove of output shaft 15 rear ends, connect planetary gear 8 and output shaft 15 by crosshead shoe 9 transition.
During use, the engage sleeves barrel spanner.When driving shaft 1 rotates, when the eccentric axial portion on it drives planetary gear 8 rotations, with interior gear cover 7 engagements, along revolution in the interior gear cover 7, increase the principle of moment of torsion according to few tooth difference deceleration, by crosshead shoe 9 power is passed to output shaft 15, be easy to dismantle the securing members such as bolt, nut of the big or corrosion of lashing force.
This device is specially adapted to not have electricity, the maintenance place or the field work of no pneumatic tool and equipment.
