Description
Technical field
The utility model relates to driving field, especially relates to a kind of involute cylindrical gear casing for driving a vehicle.
Background technique
A large amount of use involute cylindrical gear case in the driving of China in the heavy industry industry such as smelting, metallurgy, chemical industry, the energy, in using process for many years, the problem of involute cylindrical gear case ubiquity leakage of oil, and also very serious; Main leakage of oil point has two places, first place is input, output shaft annular transparent cover position, as shown in Figure 1, existing annular transparent cover 2.2 does not make any encapsulation process, only be set on input, output shaft, the fluid in such gear housing 1.1 can flow out along the gap between the axial wall of input, output shaft and annular transparent cover 2.2; In input, output shaft operation process, along with the increase of centrifugal force, the outflow of fluid can strengthen, and causes serious oil leakage phenomenon; Second place is at the screw position place of jack shaft band adjusting nut end cap 3.3, as shown in Figure 2, does not also make any encapsulation process herein, and fluid can threadingly flow out in gap, causes leakage of oil.Leakage of oil causes oil plant to waste on the one hand, pollutes site environment; The more important thing is that leakage of oil is too much, the serious consequence that internal gear also can be caused to damage during carelessness repairing.Therefore urgent hope can have a kind of solution simple, with low cost, thus thoroughly solves the Leakage of the involute cylindrical gear case of driving.
Summary of the invention
It is simple that the utility model object is to provide a kind of structure, the involute cylindrical gear casing for driving a vehicle with low cost.
For achieving the above object, the utility model can take following technical proposals:
Involute cylindrical gear casing for driving a vehicle described in the utility model, comprise gear-box body, the opposing sidewalls of described gear-box body offers input, output shaft hole respectively, described input, output shaft hole place are provided with the identical annular transparent cover of structure, the gear-box body being positioned at jack shaft axle head installed position is provided with end cap, from the annular oil storage tank being followed successively by interior land, outer retaining wall, interior retaining wall vertically outside to inside and be opened between outer retaining wall and interior retaining wall on the inner ring surface of described annular transparent cover; Described interior land is provided with outside framework oil seal, described outer retaining wall evenly offers several oil guiding holes; Described interior retaining wall evenly offers the first spill port that annular oil storage tank is connected with described gear-box chamber body by several; Distance between described first spill port and described annular transparent cover axis is greater than the distance between described oil guiding hole and annular transparent cover axis; The outer ring surface of described annular transparent cover radially evenly offers several second spill ports be connected with described first spill port, with the gear-box inner body wall of described second spill port corresponding position on offer oil guide slot, described oil guide slot extends in gear-box body.
The inner ring surface of described annular transparent cover is provided with anti-wear sleeve.
The number of described oil guiding hole, the first spill port, the second spill port is 4.
The inner side of described end cap is provided with spacer of the same size with it, the outer circumferential face of described spacer is provided with O RunddichtringO.
The utility model advantage is that structure is simple, with low cost; By the outside framework oil seal be arranged in annular transparent cover, the fluid sealing of outwards flowing out along gap is collected, and be back in gear-box body through oil guiding hole; Effective oil leakage phenomenon solving input, output shaft end, save oil plant, the pollution causing site environment because of leakage of oil can not be caused simultaneously, the more important thing is and effectively solve long-term leakage of oil, neglect repairing and cause internal gear to damage, extend the working life of gear-box, improve Security, cost-saving.By being arranged on the spacer in end cap, and O RunddichtringO being set on the outer circumferential face of spacer, fluid effectively can being stoped to flow in the thread gaps of end cap, solve Leakage herein.

Embodiment
As in Figure 3-5, involute cylindrical gear casing for driving a vehicle described in the utility model, comprise gear-box body 1, the opposing sidewalls of gear-box body 1 offers input, output shaft hole respectively, the identical annular transparent cover 2 of structure is provided with at input, output shaft hole place, the gear-box body 1 being positioned at jack shaft axle head installed position is provided with end cap 3, from the annular oil storage tank 5 being followed successively by interior land 4, outer retaining wall 7, interior retaining wall 8 vertically outside to inside and be opened between outer retaining wall 7 and interior retaining wall 8 on the inner ring surface of annular transparent cover 2; Interior land 4 is provided with outside framework oil seal 6, for sealing the fluid outwards flowed out along gap; Retaining wall 7 evenly offers several oil guiding holes 9 outside, the fluid be sealed in outside framework oil seal 6 is back in annular oil storage tank 5 by oil guiding hole 9; Interior retaining wall 8 evenly offers several by first spill port 10 of annular oil storage tank 5 with gear-box body 1 intracavity inter-connection; Distance between first spill port 10 and annular transparent cover 2 axis is greater than the distance between oil guiding hole 9 and annular transparent cover 2 axis, and the first spill port 10 is offered near the bosom of annular oil storage tank 5 groove depth as far as possible; The outer ring surface of annular transparent cover 2 radially evenly offers several second spill ports 11 be connected with the first spill port 10, and the number of oil guiding hole 9, first spill port 10, second spill port 11 is 4; With gear-box body 1 inwall of the second spill port 11 corresponding position on offer oil guide slot 12, oil guide slot 12 extends in gear-box body 1; The inner ring surface of annular transparent cover 2 is provided with anti-wear sleeve 13, and anti-wear sleeve 13 fits tightly on the axial wall of input, output shaft, can effectively reduce the wearing and tearing that outside framework oil seal 6 causes it in rotation process of input, output shaft, increase the service life.
When installing annular transparent cover 2, ensure wherein one group of oil guiding hole 9, first spill port 10, second spill port 11 is positioned at its lowest position of annular transparent cover 2, in gear-box working procedure, the fluid being positioned at gear-box body 1 can along with input, the rotation of output shaft is outwards flowed out along gap, the outside framework oil seal 6 be arranged in annular transparent cover 2 outermost end in land 4 seals and collects, be back in annular oil storage tank 5 by oil guiding hole 9, the fluid part be deposited in annular oil storage tank 5 is directly back in gear-box body 1 by the first spill port 10, another part flow in oil guide slot 12 by the second spill port 11, be back in gear-box body 1 through oil guide slot 12, thus it is inner effectively to ensure that the fluid outwards flowed out gets back to again gear-box body 1, reach sealing effect.
The inner side of end cap 3 is provided with spacer 14 of the same size with it, the outer circumferential face of spacer 14 is provided with O RunddichtringO 15, by the improvement of this structure, fluid in gear-box body 1 has not been entered end cap 3 place at O RunddichtringO 15 place by hermetic barrier, thus thoroughly solves the leakage problem of this position.
