The utility model relates to a novel electric motor car reduction gear lead oil groove device leads the oil groove and comprises a fender oil board and two oil grooves to an outer fringe is stretched out in the main part, fixes on the casing through the buckle structure that bolt fastening or itself had. Two oil grooves have certain angle, go deep into the recess of front and back casing bearing frame position simultaneously, select suitable angle of arranging, and the lubricating oil that oil baffle can splash the gear and keep off the lubricating oil that the oil muscle flows down along the casing and leading-in to two oil grooves of leading, and the effect of rethread gravity is flowed into two bearing frames of front and back shell, provides lubrication for two bearings in front and back simultaneously. The utility model discloses an electric motor car reduction gear leads two bearings of casing around oil groove structure can lubricate simultaneously, has characteristics such as fixed reliable, simple structure, simple to operate, lubricated effectual and occupation space are little.

Description

Novel oil groove device is led to electric motor car reduction gear

Technical Field

The utility model belongs to the technical field of the derailleur of automobile manufacturing, concretely relates to novel electric motor car reduction gear lead oil groove device.

Background

With the rapid increase of economy, the automobile industry develops rapidly in recent years, and the production, marketing and innovation are high. Good market performance and requirements of government policy and regulation on energy conservation, environmental protection and the like continuously promote the high-speed development of automobile technology, and new energy automobiles become the development trend in the future. The pure electric vehicle is a main development route selected by China. Therefore, development of advanced core systems such as motors and speed reducers is becoming a major task, and speed reducers for electric vehicles play a key role in aspects such as vehicle dynamics and economy.

At present, pure electric automobile speed reducers in domestic and foreign markets can be divided into parallel shaft type and coaxial type. The coaxial type volume is less, compact structure, but can bear the weight of the moment of torsion less, and NVH performance is more difficult to control. The parallel shaft type has relatively large volume, but can bear large torque and has high efficiency. Compared with the traditional fuel vehicle transmission, the electric vehicle speed reducer has the advantages of simple structure and small volume, but the input rotating speed is far higher than that of the traditional transmission, the working environments of parts such as bearings and oil seals are more severe, and the hydraulic active lubricating structure of the traditional automatic transmission is not provided.

Disclosure of Invention

The utility model aims at providing a novel oil groove device of leading of electric motor car reduction gear to the not enough of above-mentioned prior art, adopt the mode that splashes lubrication and lead that the oil structure combined together, according to the rotatory direction of splashing the fluid of gear and shells inner wall's strengthening rib structure's guide, in leading-in two bearing frames of front and back casing with the help of simultaneously with the fluid, realize the lubrication to front and back bearing. The device has two bearings of lubricated front and back casing simultaneously, leads oily effectual, fixed reliable, simple structure, simple to operate and occupation space characteristics such as little.

The utility model aims at realizing through the following technical scheme:

the utility model provides a novel oil groove structure is led to electric motor car reduction gear which characterized in that: the oil guide groove is arranged between the grooves of the bearing seats of the front shell and the rear shell, and one side of the oil guide groove is attached to a smooth oil blocking rib with radian on the shell.

The oil guide groove extends out of an outer edge and is fixed on the shell on one side through bolts or a clamping structure arranged on the oil guide groove.

The openings of the front shell groove and the rear shell groove are communicated with the bearing seat, and the size of the openings is slightly larger than the size of the part of the oil guide groove penetrating into the shell.

Because the restriction of front and back casing open-ended and lead the oil groove and pass through bolt or buckle fixed, guarantee to lead the oil groove installation fixed reliable.

The oil guide groove consists of an oil baffle plate and two oil grooves with certain inclination angles; the oil baffle plate can intercept lubricating oil splashed by rotation of the gear and lubricating oil flowing down along the oil baffle rib of the speed reducer shell. The connecting position of two oil grooves just is located the intermediate position of gear tooth thickness, has guaranteed that the fluid that the gear was thrown away and the fluid that leaves along keeping off the oily muscle can be a large amount of and two oil grooves of average inflow. The two oil grooves have certain inclination angles, and the opening position of the bearing seat is positioned above the central point of the bearing in the whole vehicle posture, so that oil intercepted by the oil baffle can smoothly flow into the bearing seats at the two ends of the front shell and the rear shell under the action of gravity, and effective lubrication of the two bearings is ensured.

Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses an electric motor car reduction gear leads two bearings of casing around oil groove structure can lubricate simultaneously, has characteristics such as fixed reliable, simple structure, simple to operate, lubricated effectual and occupation space are little.

Drawings

Fig. 1 is a structural diagram of an oil guiding groove device of a novel electric vehicle speed reducer of the invention;

fig. 2 is a layout diagram of the present invention.

In the figure, 1, a front shell 2, a rear shell 3, an oil guide groove 4, bolts 5, a front shell bearing 6 and a rear shell bearing are arranged.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1 and 2, a novel oil groove guiding device for an electric vehicle speed reducer comprises an oil groove 3, wherein the oil groove 3 is installed in the middle of grooves of a front shell 1 and a rear shell 2, and one side of the oil groove is attached to a smooth oil blocking rib with a radian on the shell. The oil guide groove 3 extends out of an outer edge and is fixed with the front shell; the recesses of the front and rear housings 1 and 2 are opened to communicate with the bearing seats, the size of the opening being larger than the size of the portion of the oil guide groove 3 extending deep into the housing. The oil guide groove 3 is fixed on the front shell 1 through a bolt 4 or a buckle on the body.

The oil guide groove 3 is composed of an oil baffle plate and two oil grooves with inclination angles, can receive lubricating oil splashed by the gear 7 and the lubricating oil flowing down along the oil baffle ribs, and flows into grooves of bearing seats on the front shell body 1 and the rear shell body 2 along the two oil grooves with inclination angles to finally lubricate a front shell body bearing 5 and a rear shell body bearing 6.
