Abstract
The utility model is a portable and saving lab our spanner, is especially applicable for disassembling and assembling a bolt of a truck tire. The spanner is provided with a torsion input gear shaft, a pair of medial drive gears and a torsion output gear, wherein the torsion output gear and the torsion input gear shaft are arranged with the concentricity, the torsion input gear shaft is meshed with the big gear of the medial drive gear, the small gear of the medial drive gear is meshed with the torsion output gear, the manpower is transferred to the torsion input gear shaft by the device like the crank, and further transfer to the big gear of the medial drive gear and to the torsion input gear shaft by the small gear of the medial drive gear. The spanner provided by the utility model adopts the 2 level decelerating gears, so as to increase the output torsion, when the automobile is failure about the tire on the way, only need one person quickly and easily finish disassembling and assembling the automotive tire bolt by the spanner.
Description
The utility model relates to a kind of light, labour-saving tool wrench, especially is specifically designed to the reinforcement spanner of the dismounting of truck tyre bolt.
When tire fault occurring in automobile is travelling the way, often need the dismounting tire bolt, the purpose of this utility model provides a kind of spanner, uses this spanner one people just can finish the disassemble and assemble work of motor tire bolt fast, effortlessly.
To achieve these goals, this spanner that the utility model provides has a moment of torsion input gear axle, an a pair of intermediate drive gear and a moment of torsion output gear, wherein, moment of torsion output gear and moment of torsion input gear axle arranged concentric; Torque input shaft is installed by Upper shaft sleeve and Lower shaft sleeve, and Upper shaft sleeve is contained in the blind hole of moment of torsion output gear, and Lower shaft sleeve is installed on the U-shaped pressing plate; The last lower shaft end of intermediate drive gear is installed in the axle sleeve of a flange and U-shaped pressing plate; Torque input shaft is meshed with the big gear wheel of intermediate drive gear, the miniature gears of intermediate drive gear is meshed with the moment of torsion output gear, manpower passes to torque input shaft by allied equipments such as cranks, and then passing to the big gear wheel of intermediate drive gear, the miniature gears by intermediate drive gear passes to the moment of torsion output gear then.
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is an External view of the present utility model.
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, spanner of the present utility model has a moment of torsion input gear axle 2, an a pair of intermediate drive gear 8 and a moment of torsion output gear 1, wherein, moment of torsion output gear 1 and moment of torsion input gear axle 2 arranged concentric; Torque input shaft 2 is installed by Upper shaft sleeve 3 and Lower shaft sleeve 4, and Upper shaft sleeve 3 is contained in the blind hole of moment of torsion output gear 1, and Lower shaft sleeve 4 is installed on the U-shaped pressing plate 6; The last lower shaft end of intermediate drive gear 8 is installed in the axle sleeve of a flange 14 and U-shaped pressing plate 6; Torque input shaft 2 is meshed with the big gear wheel of intermediate drive gear 8, the miniature gears of intermediate drive gear 8 is meshed with moment of torsion output gear 1, manpower passes to torque input shaft 2 by allied equipments such as cranks, and then passing to the big gear wheel of intermediate drive gear 8, the miniature gears by intermediate drive gear 8 passes to moment of torsion output gear 1 then.
Garden, the lower end spindle nose of moment of torsion output gear 2 is contained in the sliding sleeve 9, and sliding sleeve 9 is installed in the fixed cover 10, fixed cover 10 and flange 14 welding.Fixed cover 10 peripheries are provided with the fixed cover barrier part 11,12,15 of hollow, and the upper end 15 of described fixed cover barrier part 11,12,15 is fixed on the described flange 14.Fixed cover barrier part 11,12,15 lower ends are fixed with a cutting ferrule 12, and described cutting ferrule 12 is provided with fixed orifice.Fixed orifice on the cutting ferrule 12 is a hexagon.The lower end of moment of torsion output gear 2 garden spindle noses has a square hole, in order to the moving casing spanner to be installed.Flange 14 1 ends of spanner have and prevent that spanner from setting level the plane of rolling in the back.Spanner is provided with torsion scale display disc.
Tire fault appears in automobile is travelling the way, when needing the dismounting tire bolt, with the opening sleeve of cutting ferrule 12 in nut, insert the moving casing spanner in the square opening of moment of torsion output gear 2 lower ends, the hexagon ring of spanner is inserted on the adjacent nut, shake crank, cap key and the huge torsion that fixedly produces between the cutting ferrule can be unscrewed bolt or tighten.
Spanner provided by the utility model has increased output torque owing to adopted 2 grades of reducing gear, so only needs a people just can finish the disassemble and assemble work of motor tire bolt fast, effortlessly.
