Abstract

The utility model discloses a speed reducer. An oil collecting disc is arranged on the inner surface at the top of a box body, and an oil discharge outlet is arranged on the oil collecting disc and positioned above oil bags on both sides of the box body. In the speed reducer provided in the utility model, the oil collecting disc is arranged on the inner surface at the top of the box body and can collect splashed lubricating oil, and the splashed lubricating oil respectively flows into the oil bags on both sides of the box body and then are introduced to the upper part of bearings through an oil path to lubricate. As the oil collecting disc can collect the splashed lubricating oil, and the lubricating oil is averagely distributed into the oil bags on both sides of the box body to lubricate the bearing on the two sides, the speed reducer solves the problem of non-uniform lubrication of the bearings on the left side and the right side of the traditional speed reducer.

Description

Speed reducer

Technical field

The utility model relates to field of mechanical technique, more particularly, relates to a kind of speed reducer.

Background technique

Speed reducer belongs to power and passes on mechanism, is a kind of velocity transducer that utilizes gear, the winding number of motor is decelerated to desired winding number, and obtain the mechanism of big torque.Its application is more extensive, from the transmission work of big power, can see to little load, accurate angle transmission, and on commercial Application, speed reducer has deceleration and increases the torque function.

In the running of speed reducer, friction pair and bearing need lubricate in the speed reducer casing, and wherein, intermeshing a pair of gear and tooth axle have just constituted a pair of friction pair.Generally speaking, thermal power for the balance speed reducer, can not be full of lubricant oil in the casing, at this moment, the parts that are not immersed under the pasta mainly lean on splash lubrication, described splash lubrication is by part in the casing, and the rotation that promptly refers to the friction pair in the casing is taken lubricant oil to friction pair and bearing forms self oiling from oil sump.For better lubricating bearings, also designed oil sac on casing top, after the oil that splashes enters oil sac,, be lubricated from the bearing top at last by the oil circuit of processing on the casing.

Since casing internal tooth axle and gear arrange and asymmetric, so uneven about the oil mass that will cause splashing, make left and right sides bearing lubrication inequality.

The model utility content

In view of this, the utility model provides a kind of speed reducer, to solve the problem of the left and right sides bearing lubrication inequality that has speed reducer now.

Described speed reducer, the internal surface on its casing top is provided with oil drip pan, and this oil drip pan is provided with oil drain out, and this oil drain out is positioned at oil sac top, described casing both sides.

Preferably, the cross section of described oil drip pan upper surface is arc or triangle.

Preferably, described oil drip pan by screw on the internal surface on described casing top.

From above-mentioned technological scheme as can be seen, the speed reducer that the utility model provides, the internal surface on its casing top is provided with oil drip pan, this oil drip pan can be collected the lubricant oil that splashes, flow into the oil sac of casing both sides respectively by oil drain out, introduce the bearing top by oil circuit again and be lubricated.Because described oil drip pan can be collected the lubricant oil that splashes, be assigned in the oil sac of casing both sides, lubricate the bearing of both sides, solved the problem of the left and right sides bearing lubrication inequality of existing speed reducer.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

The utility model embodiment discloses a kind of speed reducer, to solve the problem of the left and right sides bearing lubrication inequality that has speed reducer now.

Referring to Fig. 1 and Fig. 2, the internal surface on described speed reducer casing top is provided with oil drip pan 1, and this oil drip pan is provided with oil drain out, and this oil drain out is positioned at oil sac 2 tops, described casing both sides.

Collect the lubricant oil that splash for convenience, oil drip pan 1 generally is installed in the top of described speed reducer casing internal gear teeth axle engaging piece more.Along with the engagement rotation of gear and tooth axle, lubricant oil can splash along sense of rotation, collects through oil drip pan 1.

Through oil drip pan 1 collected lubricant oil, the direction of following the arrow, flow into the oil sac 2 of casing both sides by oil drain out, act on the bearing 4 of casing both sides again by the oil circuit 3 of casing both sides, because the lubricant oil that splashes can be through oil drip pan 1 centralized collection, be redistributed to the bearing 4 of casing both sides, the lubricant oil inequality that has solved because of the left and right sides bearing that flows into speed reducer causes its lubricated uneven problem.

Concrete, oil drip pan 1 can certainly, can also adopt other Placements, as long as can satisfy fixedly oil drip pan by screw on the internal surface on described speed reducer casing top.

For oil drip pan distribute lubrication oil in the foregoing description of being more convenient for, the utility model is another embodiment also provide a kind of speed reducer, different with the foregoing description is, the cross section that is arranged at the oil drip pan 1 on the internal surface on described speed reducer casing top is triangle or convex, specifically as shown in Figure 3 and Figure 4.

This oil drip pan is a tinsel, is generally stalloy, flows the intermediate portion projection of oil drip pan for the ease of what collect lubricant oil on the oil drip pan 1.Like this, the lubricant oil of collecting on the oil drip pan 1 can directly flow into the oil sac of casing both sides directly along being flowed down to the inclined-plane that both sides form by the centre by oil drainage hole.

Certainly, disclosed oil drip pan can also can be fixed by other Placements by screw on the internal surface on casing top in the present embodiment.

Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and other embodiments' difference that identical similar part is mutually referring to getting final product between each embodiment.

To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
