Description

Worm speed reducer capable of preventing engine oil from splashing

Technical Field

The utility model belongs to the technical field of machinery, a prevent worm speed reducer that machine oil splashes is related to.

Background

The worm speed reducer is a common speed reducer with a relatively simple structure and a large reduction ratio, and has the characteristics of good stability, small size and the like, however, because the input shaft is perpendicular to the output shaft and the meshing part is small, in the operation process, engine oil has a large free space, so that the engine oil splashes to the inner wall of the shell in the operation process, and the engine oil is adhered to the inner wall of the shell to be solidified, thereby not only causing the waste of the engine oil, but also ensuring that the maintenance period of the speed reducer is short.

Generally speaking, if need make the machine oil maintenance cycle of speed reducer longer, need once only pour into a great deal of machine oil into, however, more machine oil, cause the degree that splashes to be bigger, the worm is as high-speed end, and it is more to produce the heat, and is bigger to the stirring intensity of machine oil, and traditional worm speed reducer is for the convenience of driving motor's installation, sets up the worm in the top of worm wheel pivot, causes the worm lubrication unsatisfactory very easily, and causes the machine oil problem of splashing more serious.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that exists to current technique, provide a prevent worm speed reducer that machine oil splashes, the utility model aims to solve the technical problem that how prevent that machine oil from splashing and causing the waste.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a prevent worm speed reducer that machine oil splashes, its characterized in that, this worm speed reducer include the worm, with worm meshing's worm wheel and casing, the worm rotates to be connected on the casing, the worm wheel rotates through the pivot to be connected on the casing, the worm is perpendicular with the pivot, the worm is located the below of pivot, the fixed apron that is located the worm top that is provided with on the shells inner wall, the outer lane of apron has an annular, the mouth of dodging that has the bar on the worm, the worm wheel part inserts dodge in the mouth, form a parcel between apron and the casing bottom the oil pocket of worm, the through-hole that has intercommunication annular and oil pocket on the apron, the oil pocket intussuseption is filled with and accounts for the volumetric machine oil of oil pocket third at least.

Under the effect of apron and worm wheel, the oil pocket is in a relative sealed state, and the engine oil that partial entering was gone up to the apron also can get into the oil pocket again through annular and through-hole, and generally speaking, except can taking a breath, engine oil is difficult to be followed and dodged the mouth and is discharged, and the screw thread structure of worm itself makes the moving direction of engine oil in the oil pocket tend to the axis direction of worm, makes the problem that engine oil splashes less, and the worm wheel also can receive better lubrication.

The worm is a main heating component due to the fact that the rotating speed is high, the worm is partially soaked in engine oil, the heat dissipation effect is good, the amount of the engine oil in the shell of the whole speed reducer is not too large, and the maintenance period is long.

In the above worm speed reducer for preventing engine oil from splashing, an oil drain hole communicated with the oil cavity is formed in the bottom of the casing, and a plug is inserted into the oil drain hole.

Fig. 1 is a schematic structural view of the worm speed reducer.

In the figure, 1, a worm; 2. a worm gear; 3. a housing; 4. a cover plate; 41. a ring groove; 42. avoiding the mouth; 43. an oil chamber; 44. a through hole; 5. and (7) a plug.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, the worm 1 speed reducer comprises a worm 1, a worm wheel 2 meshed with the worm 1 and a shell 3, wherein the worm 1 is rotatably connected to the shell 3, the worm wheel 2 is rotatably connected to the shell 3 through a rotating shaft, the worm 1 is perpendicular to the rotating shaft, the worm 1 is positioned below the rotating shaft, a cover plate 4 positioned above the worm 1 is fixedly arranged on the inner wall of the shell 3, an annular groove 41 is formed in the outer ring of the cover plate 4, a strip-shaped avoiding opening 42 is formed in the worm 1, part of the worm wheel 2 is inserted into the avoiding opening 42, an oil cavity 43 wrapping the worm 1 is formed between the cover plate 4 and the bottom of the shell 3, a through hole 44 communicating the annular groove 41 with the oil cavity 43 is formed in the cover plate 4, and the oil cavity 43 is.

Under the action of the cover plate 4 and the worm wheel 2, the oil chamber 43 is in a relatively sealed state, and part of engine oil entering the cover plate 4 can enter the oil chamber 43 again through the ring groove 41 and the through hole 44, generally, besides ventilation can be performed, the engine oil is difficult to discharge from the avoiding opening 42, and due to the thread structure of the worm 1, the moving direction of the engine oil in the oil chamber 43 tends to the axial direction of the worm 1, so that the problem of engine oil splashing is small, and the worm wheel 2 can be well lubricated.

The worm 1 is a main heating component due to the fact that the rotating speed is high, the worm 1 is partially soaked in engine oil, the heat dissipation effect is good, the amount of the engine oil stored in the shell 3 of the whole speed reducer is not too large, and the maintenance period is long. An oil drain hole communicated with the oil cavity 43 is arranged at the bottom of the shell 3, and a plug 5 is inserted in the oil drain hole.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
