Abstract
A kind of brill ground trench excavator uni-drive gear box, it is characterized in that uni-drive gear box is casing, case lid round sealed combining structure, moment is inputted by input shaft end, input shaft and drive bevel gear are designed to the input gear axle of integrative-structure, the gears meshing of input gear axle is large by dynamic bevel gear, all gears are two end supports structure, eventually through output shaft output torque.Technique effect of the present utility model is: gearbox drive steadily reliable, adequate rigidity, small-power with exporting the brill of high pulling torque function of digging pit can be realized, and compact structure, low cost of manufacture, noise is little, long service life.
Description
Technical field
The utility model relates to a kind of uni-drive gear box, with particularly relating to a kind of brill uni-drive gear box of digging pit.
Background technique
Bore ground trench excavator be a kind of for trees planting of digging pit, clear up stub beautify the machine tool with greening environment, be a kind of efficient mechanical.Traditional brill ground trench excavator is generally the motor drilling ground machine that hand half the circumference of the sleeve where it joins the shoulder shoulders formula, and gear-box output torque is little, and machine needs a people even many people manpower support operation, digs pit at the bottom of efficiency, dangerous, and requires higher to soil quality situation, and working life is short.
Summary of the invention
The purpose of this utility model is power transmission gearbox of digging pit with there are provided a kind of airborne efficient drilling, this gearbox drive is reliable, adequate rigidity steadily, small-power with driving the brill of high pulling torque output function of digging pit can be realized, and it is adaptable to soil hardening, compact structure is attractive in appearance, drive noise is little, low cost of manufacture, long service life.
The utility model is achieved like this, its bore uni-drive gear box of digging pit, comprise input gear axle, casing, case lid, by dynamic bevel gear, output shaft, input gear axle, output shaft and greatly by dynamic bevel gear are installed in casing, gears meshing on input gear axle is large by dynamic bevel gear, is driven output shaft greatly by dynamic bevel gear by connecting key; Case lid is installed at casing top, it is characterized in that casing, case lid adopt round sealed combining structure.
Described large be two end supports mode by dynamic bevel gear, modulus is 5, and gear pair has tooth number Z 1=11 and the Z2=35 of larger mutual prime rwmber.
Technique effect of the present utility model is: single-stage driving gearbox drive is more steadily efficient; Casing, case lid are round sealed combining structure, stiffening rib major part is built-in, the input gear axle design of one, and gear pair is the layout of two end supports structure, while enhancing gear box structure rigidity, the compact, attractive in appearance of gear-box and low cost are taken into account; Casing major part stiffening rib is built-in and box body wall shell is camber line stair structure makes cabinets cavity surface be blocked into many little anchor rings being conducive to absorbing gear vibration and noise in addition, reduces the drive noise of gear-box; Suitable bevel gear modulus 5 and enough gear housing rigidities, make gear-box can be good at adapting to small-power with driving the brill of high pulling torque output function of digging pit; Gear pair has tooth number Z 1=11 and the Z2=35 of larger mutual prime rwmber, make gear can avoid single tooth always within very little mesh cycle with same tooth engaging stress, improve the gear transmission life-span.
Accompanying drawing explanation
Fig. 1,2,3 is structural representation of the present utility model.
Fig. 4-9 is the structural representation of casing described in the utility model.
Figure 10-14 is the structural representation of case lid described in the utility model.
In the drawings, 1, input gear axle 2, casing 3, case lid 4, greatly by dynamic bevel gear 5, output shaft 6, box house stiffening rib 7, casing external reinforcing muscle 8, casing camber line stair structure 9, gear shaft two end supports structure 10, case lid internal stiffeners 11, case lid external link structure.
Embodiment
As shown in Figure 1, 2, 3, uni-drive gear box of digging pit this brill comprise input gear axle 1, casing 2, case lid 3, by dynamic bevel gear 4, output shaft 5, input gear axle 1, output shaft 5 and greatly by dynamic bevel gear 4 are installed in casing 2, power is inputted by input gear axle 1, gears meshing on input gear axle 1 is large by dynamic bevel gear 4, output shaft 5 is driven by connecting key greatly, final increase also output torque by dynamic bevel gear 4; Case lid 3 is installed at casing 2 top, it is characterized in that casing 2, case lid 3 adopts round sealed combining structure.
Described large be two end supports mode by dynamic bevel gear 4, modulus is 5, and gear pair has tooth number Z 1=11 and the Z2=35 of larger mutual prime rwmber.
As shown in figures 4-9, described casing 2 is round structure, casing is provided with many places box house stiffening rib 6 and casing external reinforcing muscle 7, but most of stiffening rib is all at box house, box body wall shell is camber line stair structure 8 in addition, and input gear axle 1 installation place of casing 2 adopts gear shaft two end supports structure 9.
As shown in figures 10-14, described case lid 3 is round structure, and case lid 3 is also provided with case lid internal stiffeners 10 in addition, and is provided with two external link structures 11 perpendicular to case lid face.Like this, after casing and case lid are assembled, form input gear axle two end supports structure 9, output shaft 5 is also combined the sealing configuration of a two end supports by casing, case lid in addition, these functions making gear-box dig pit with can be good at adapting to the brill of small-power drive high pulling torque all more simultaneously, have compact structure concurrently, low cost of manufacture, noise is little, the advantage of long service life.
