Description
Technical field
The utility model relates to a kind of gear-box, especially related genera Gear Planet Transmission or quasi-planet uni-drive gear box.
Background technique
In gear box designs, often run into due to structural restriction, and desirable design of having to change, accept a less-than-ideal scheme or realized by the structural change of more complicated.Such as, glory-hole electric power wheel self-discharging vehicle electric wheel (Chinese Patent Application No.: the scheme 200620051330.4), structure is more complicated.Existing product in the market, be all the structure that torque tube and ring gear are integrated (part), this Standard is pretty troublesome, and gear is difficult to realize all carrying, thus affects the gear train assembly life-span.
Summary of the invention
The purpose of this utility model is to provide one to be convenient to component assembling, can realize the gear box structure that gear train assembly all carries.
The technological scheme realizing the utility model object is: a kind of gear box structure, comprise support, sealing seat, limited ring, torque tube, ring gear, gear shaft, bearing cap, clutch shaft bearing and the second bearing, described support is fixedly connected with sealing seat, the large-diameter portion of described limited ring is contained on sealing seat, the minor diameter part of limited ring has the first protrusion, described torque tube is fixedly connected with limited ring, there is in described torque tube internal spline and second protrude, ring gear periphery has external splines, torque tube and ring gear are by inside and outside spline fitted, first protrusion and second protrudes the two end part laying respectively at ring gear, described gear shaft engages with ring gear, gear shaft has some and is circle distribution, the outer ring of described clutch shaft bearing is installed on one end of support and is fixed by bearing cap, the outer ring of described second bearing is installed in the bearing saddle bore of the support the other end, the two ends of gear shaft described in every root are supported in corresponding clutch shaft bearing and the second bearing respectively.
Described sealing seat has installation annular groove, and limited ring has annular projection, and annular projection is inserted into be installed in annular groove and forms labyrinth seal with installation annular groove.
Described support is fixedly connected with by the first bolt with sealing seat.
Described torque tube has mounting flange, and torque tube is fixedly connected with limited ring by briquetting, the second bolt, mounting flange.
Described bearing cap is fixed on one end of support by bearing pin and screw.
After adopting said structure, because torque tube and ring gear are by inside and outside spline fitted, instead of the structure of one (part), therefore, be convenient to assembling, floating of ring gear, realizes all carrying of gear train assembly.The utility model solves gear-box inner pedestal and protrudes, and component assembling difficult problem, is specially adapted to ring gear and installs the structure needing to protrude through this bearing support; In addition the utility model structure is also fairly simple, and cost is low, and the life-span is long.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of gear box structure of the present utility model;
Fig. 2 is the top zoomed-in view of Fig. 1;
Fig. 3 is the sectional view of Fig. 2 along A-A.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
As Fig. 1, 2, shown in 3, a kind of gear box structure, comprise support 1, sealing seat 2, limited ring 3, torque tube 5, ring gear 6, gear shaft 7, bearing cap 8, clutch shaft bearing 9 and the second bearing 12, described support 1 is fixedly connected with sealing seat 2, the large-diameter portion of described limited ring 3 is contained on sealing seat 2, the minor diameter part of limited ring 3 has the first protrusion 3-1, described torque tube 5 is fixedly connected with limited ring 3, there is in described torque tube 5 internal spline and second and protrude 5-1, ring gear 6 periphery has external splines, torque tube 5 and ring gear 6 are by inside and outside spline fitted, first protrudes 3-1 and second protrudes the two end part that 5-1 lays respectively at ring gear 6, described gear shaft 7 engages with ring gear 6, gear shaft 7 has some and is circle distribution, the outer ring of described clutch shaft bearing 9 is installed on one end of support 1 and is fixed by bearing cap 8, the outer ring of described second bearing 12 is installed in the bearing saddle bore 1-1 of support 1 the other end, the two ends of gear shaft 7 described in every root are supported in corresponding clutch shaft bearing 9 and the second bearing 12 respectively.
As shown in Figure 2, described sealing seat 2 has installs annular groove 2-1, and limited ring 3 has annular projection 3-2, and annular projection 3-2 is inserted into and installs in annular groove 2-1 and form labyrinth seal with installation annular groove 2-1.
As shown in Figure 1, described support 1 is fixedly connected with by the first bolt 13 with sealing seat 2.
As shown in Figure 2, described torque tube 5 has mounting flange 5-3, and torque tube 5 is fixedly connected with limited ring 3 by briquetting 4, second bolt 14, mounting flange 5-3.
As shown in Figure 3, described bearing cap 8 is fixed on one end of support 1 by bearing pin 10 and screw 11.
As shown in Figure 1, 2, 3, in an assembling process, because the path 5-2 place size in torque tube 5 is less, and clutch shaft bearing 9 installed by support 1 and the rear size of bearing cap 8 is larger.Need to implement in the following order, first gear shaft 7 is installed, sealing seat 2 is installed on support 1, limited ring 3 is first positioned over sealing seat 2, ring gear 6 is positioned over limited ring 3, then clutch shaft bearing 9 is positioned over the bearing support position of support 1, bearing cap 8 is installed on support 1 by bearing pin 10 and screw 11, and then torque tube 5 is installed, now, limited ring 3 is connected by briquetting 4 and bolt with torque tube 5, because the position of torque tube 5 is fixed, fix making the position of limited ring 3, the position of ring gear 6 is fixed by the protrusion 3-1 on limited ring 3 and torque tube 5 must protrude 5-1.Because the radial position of ring gear 6 is not fixed, float and realize all carrying of gears meshing.
