Abstract
An anti-leakage plug device for speed reducers of electric forklifts comprises an electric forklift speed reducer box (4), an input shaft (2) and a deep groove ball bearing (1), the input shaft (2) is fixed on the inner circle of the deep groove ball bearing (1), the outer circle of the deep groove ball bearing (1) is fixed on the electric forklift speed reducer box (4), a hole (20) is formed in the input shaft (2), a step (21) is formed on the hole (20), a plug cover (3) is fastened in the hole (20) of the input shaft (2) and pressed on the step (21), and a bowl-shaped cover (31) is wrapped by a rubber layer (32) to form the plug cover (3). Oil cannot leak after the anti-leakage plug device is used for a long time, and moreover, the fabrication cost is low as well.
Description
Technical field:
The utility model relates to the retarder technical field, more specifically to employed leakproof plug on the Electric Fork Lift Trucks reducer input shaft.
Background technique:
At present, China is that Electric Fork Lift Trucks provides supporting power transmission assembly (retarder) structure to mainly contain two kinds: first kind is the disposed upright formula, and second kind is transverse.First kind of sealing structure is relatively good, and the situation that does not have leakage of oil basically takes place.Second kind because the needs of input shaft processing are made hollow gear shaft, thereby have caused the defective in the design, become flexible or process coarsely as long as have on motor and the gearbox junction surface, will produce the problem of leakage of oil.Electric Fork Lift Trucks is mainly used in indoor place, and ground, serious generation security incident are polluted in the leakage of oil meeting.We have carried out multiple test: adopted the sticking plug of electric welding weldering plug and Bond, all undesirable, the precision that electric welding not only can influence axle because of thermal distortion also reduces the intensity of axle, and Bond is of long duration can inefficacy.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology, and a kind of Electric Fork Lift Trucks retarder leakproof plug device is provided, and it uses oil-proof for a long time, and fabricating cost is also low.
The technological solution of the utility model is following:
Electric Fork Lift Trucks retarder leakproof plug device; Comprise Electric Fork Lift Trucks reduction case, input shaft and deep groove ball bearing, input shaft is fixed on the inner ring of deep groove ball bearing, and the outer ring of deep groove ball bearing is fixed on the Electric Fork Lift Trucks reduction case; Input shaft forms hollow hole; Form step on the hollow hole, plug covers in the hollow hole that is fastened on input shaft and is pressed against on the step, and the plug lid is made up of the bowl-shape cladding rubber layer that covers.
Said rubber layer is bowl-shape rubber cap, and bowl-shape rubber cap is enclosed within bowl-shape covering and forms the bowl-shape cladding rubber layer that covers.
Said rubber layer is adhesively fixed on bowl-shape covering and forms the bowl-shape cladding rubber layer that covers.
The beneficial effect of the utility model is:
Through evidence, the utility model can use oil-proof in the permission serviceability temperature scope of gearbox for a long time, and fabricating cost is also low.
Description of drawings:
Fig. 1 is the structural representation of the utility model
The sectional exploded view that Fig. 2 cooperates with input shaft for the plug lid.
Among the figure: 1, deep groove ball bearing; 2, input shaft; 20, hollow hole; 21, step; 3, plug lid; 31, bowl-shape lid; 32, rubber layer; 4, Electric Fork Lift Trucks reduction case.
Embodiment:
Embodiment: see Fig. 1, shown in 2; Electric Fork Lift Trucks retarder leakproof plug device; Comprise Electric Fork Lift Trucks reduction case 4, input shaft 2 and deep groove ball bearing 1, input shaft 2 is fixed on the inner ring of deep groove ball bearing 1, and the outer ring of deep groove ball bearing 1 is fixed on the Electric Fork Lift Trucks reduction case 4; Input shaft 2 forms hollow hole 20; Form step 21 on the hollow hole 20, plug lid 3 is fastened in the hollow hole 20 of input shaft 2 and is pressed against on the step 21, and plug lid 3 is made up of cladding rubber layer 32 on the bowl-shape lid 31.
Said rubber layer 32 is bowl-shape rubber cap, and bowl-shape rubber cap is enclosed within and forms cladding rubber layer 32 on the bowl-shape lid 31 on the bowl-shape lid 31.
Said rubber layer 32 is adhesively fixed on and forms cladding rubber layer 32 on the bowl-shape lid 31 on the bowl-shape lid 31.
Working principle: because rubber has elasticity, plug lid 3 just can be fastened in the hollow hole 20 like this, is blocking up hollow hole 20 preferably, thereby is preventing input shaft 2 leakage of oils.The utility model can use oil-proof in the permission serviceability temperature scope of gearbox for a long time, and fabricating cost is also low.
