Abstract

The utility model relates to a gear box oil return channel on a truck, in particular to an oil return channel device of electric wheel gear box on power drive truck, which comprises a screw thread inner plug, a screwed conduit, a flange disc, a rubber joint and a pipe strap, wherein the screw thread inner plug is fixed in a frame oil return channel hole, the screwed conduit is connected with screw threads of the screw thread inner plug in the frame oil return channel hole, silica gel is filled in a hollow cavity between the screw thread pipe and the frame oil return channel hole, the center hole of the flange disc is sleeved on the screw thread pipe to lead the center hole of the flange disc to be concentric with the frame oil return channel hole, and the flange disc is fixed on the inner wall of the gear box, the rubber joint is sleeved on the short node of the flange disc and the screw thread pipe, and the rubber joint is firmly clamped by the pipe strap. The oil return channel device of electric wheel gear box on power drive truck greatly reduces stress concentration caused by vibration generated by truck load after changing the rigid oil return channel to flexible connection, overcomes the shortcomings in structure and design, fundamentally and effectively avoids the phenomenon of oil leakage because of cracks on the oil return channel hole, and saves a great amount of funds for enterprises.

Description

The back oil road device of electric wheel gear-box on the electric drive truck
Technical field
The utility model relates to the gear-box back oil road on a kind of truck, the back oil road device of electric wheel gear-box on specifically a kind of electric drive truck.
Background technique
A hundred or so many of the existing electric drive truck in An Taibao ore deposit, as the prolongation along with operation hours of the electric wheel of truck critical component, total member is aging year by year, and rate of fault obviously raises, the corresponding increase of input cost.Wherein electric wheel causes the phenomenon of leakage of oil especially outstanding because of the back oil road crack, its rate of fault accounts for 80%~90% of electric wheel fault sum, because the defective in the design of GE776KSA1 type electric wheel, cause the gear-box back oil road to cause leakage of oil because of truck the crack occurs in the vibrations under the heavy duty, this fault becomes the key factor that troubles the normal use of electric drive truck.The generation of this fault mainly is due to the defective on the structural design.Because adopt non-integral to be welded between the gear-box of electric wheel and the frame, the outside of gear-box is evenly distributed along the gear-box periphery by six block welding plates and welds, the back oil road of three planet holes of gear-box inside, center hole and lower curtate all docks with frame along separately aperture edge.Being connected to belong to fully and being rigidly connected between gear-box and the frame like this.Leave about 150 mm distance between gear-box and the frame.Truck will produce vibrations between the frame body of casting and the gear-box under the condition of sharply load, the frame inboard bends.Meanwhile, the gear-box inwall will produce bigger alternating stress.In the back oil road outlet port, stress distributes around circular hole, stress occurs and concentrates, and will inevitably produce the crack, is inevitable so cause leakage of oil.Therefore, want to improve electric wheel working life, avoid the generation of this fault, the transformation of carrying out back oil road is imperative.
Once taked directly to dig the mode of welding crackle and carrying out repair welding at the oil return road junction on every side and carried out processing, but all end in failure, the crack occurs in the same old way.Frequent leakage of oil meeting causes the insufficient lubrication of drive part, even can cause the integral body of transmission system to be damaged.This problem once became one of principal element of puzzlement truck turnout.
Summary of the invention
The purpose of this utility model provides a kind of can avoiding and the back oil road device that the crack causes electric wheel gear-box on the electric drive truck that oil leakage phenomenon takes place occurs because of the oil return road junction.
The technical scheme in the invention for solving the technical problem is: it is by filling in the screw thread, threaded pipe, flange plate, elastomer connector, pipe clamp is formed, plug is fixed in the back oil road hole of frame in the screw thread, threaded pipe is threaded with the interior plug of the screw thread in the frame back oil road hole, filling gel in the cavity between the back oil road hole of threaded pipe and frame, the flange plate center hole is enclosed within on the threaded pipe, make the flange plate center hole concentric with the back oil road hole of frame, and flange plate is fixed on the gear-box inwall, elastomer connector is enclosed within on flange plate pipe nipple and the threaded pipe, with pipe clamp it is fastened.
So original rigidity back oil road is transform as flexibly connect after, reduced greatly to plant and produce the stress that vibrations cause and concentrate because of truck is negative, remedied the defective of structural design.Fundamentally effectively avoided the generation that the crack causes oil leakage phenomenon occurring because of the oil return road junction.This innovation at present is generalized to the GE776KSA1 type from the GE788KSF5 type, and positive promoting effect has been played in development from now on to truck.
Every can economize on the use of funds 5.8 ten thousand yuan (according to spoilages of transmission system 70%) successfully transformed 12 in 2004, economized on the use of funds 69.6 ten thousand yuan.Successfully transform 20 in 2005, and economized on the use of funds 1,160,000 yuan.Up to the present this project (is transformed still and is being continued) from coming into effect, and economizes on the use of funds 185.6 ten thousand yuan altogether.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model,
Among the figure, 1. plug in the screw thread, 2. threaded pipe, 3. frame, 4. silica gel, 5. gear-box inwall, 6. flange plate, 7. elastomer connector, 8. pipe clamp.
Embodiment
The utility model by fill in 1 in the screw thread, threaded pipe 2, flange plate 6, elastomer connector 7, pipe clamp 8 form, plug 1 is fixed in the back oil road hole of frame 3 in the screw thread, threaded pipe 2 is threaded with the interior plug 1 of the screw thread in the frame 3 back oil road holes, filling gel 4 in the cavity between the back oil road hole of threaded pipe 2 and frame 3, flange plate 6 center holes are enclosed within on the threaded pipe, make the flange plate center hole concentric with the back oil road hole of frame, and flange plate is fixed on the gear-box inwall, elastomer connector 7 is enclosed within on the pipe nipple and threaded pipe 2 of flange plate 6, with pipe clamp 8 it is fastened.
Concrete processing and assembling step is as follows: at first planet wheel is separated frame 3, with the cutter of suitable diameter along back oil road outlet carrying out bore hole, boring gear-box and frame 3 the soldering point that disappears at this place, cause frame 3 and gear-box to break away from, guarantee the integrity of gear-box, plug in the pipe thread 1 is inserted in frame 3 holes, and adopt argon arc welding that it is welded, the position that plug 1 inserts in the screw thread can not be higher than frame 3 base planes, in order to avoid influence the installation of platen, 3/4 " the thread surface of threaded pipe 2 coat screw thread glue; then it is assembled in the pipe thread that is welded in the frame 3 in the plug 1; filling gel in the cavity between threaded pipe 2 and frame 3 back oil road holes, locating flange dish 6 welds with gear-box inwall 5, and " threaded pipe 2 is positioned at the center of its endoporus to guarantee 3/4, elastomer connector 7 is enclosed within flange plate 6 and 3/4 " on the threaded pipe 2; then, to be fastened it with pipe clamp 8 respectively, transforms and finish after 24 hours and can install and use.
