Abstract
Disclosed is a rotating gear motor with a hydraulic shell for coal mine machinery, which is composed of a hydraulic motor and a planetary reducer combined together. The hydraulic motor is connected with a primary centre gear through an inner spline shaft; the primary centre gear is connected with a gear box shell for outputting the rotating speed and the power through a primary planetary gear, a planetary small shaft and a primary carrier which is fixed on a left frame through a bolt; the gear box shell and a primary gear sealing cover are fixed together through the bolt; two bearings with strong radial force are fixed on the gear box shell and the left frame by a clasp through a hole; the left frame and the gear box shell are sealed through a floating seal ring. the hydraulic motor and the reducer are respectively as an individual one and also are combined together, which enhances the maintenance convenience effectively and is helpful to be standardized. The utility model has the advantages of easy manufacture, reliable structure, stable performance and low cost.
Description
Technical field
The utility model relates to a kind of gear drive that comprises oil hydraulic motor, especially a kind of reduction gear transmission device that utilizes the oil hydraulic motor transmission.
Background technique
The mekydro motor of China all depends on the import of product for a long time, particularly on coal mine machinery equipment.Italy SAI motor adopts unique tilt cylinder structure, each parts is stressed and moving condition is all better, though it is bigger that quality and size are compared high-speed motor, but use rotating speed moderate, and flexible configuration, startability and low-speed characteristic are good, and these all provide good assurance for its application on gear motor.But the price of the mekydro motor of external import is higher, is difficult to satisfy domestic to demand good and cheap and reliable performance and stable hydraulic gear motor.Particularly on prosperous day by day in recent years coal mine machinery, the mekydro motor satisfies the needs that it increases as a kind of explosion-proof and high technology content equipment that recruitment is few with the domestic development of increasing dependence.On market, can buy relevant hydraulic moving gear motor product at present, and on the Chinese patent communique, also can find the correlation technique data of relevant hydraulic moving gear motor.Existing known hydraulic moving gear motor, its structure mainly is made of oil hydraulic motor and planetary reducer, described hydraulic moving gear motor all adopts the high speed axial plunger type motor, its pressure, efficient, and the life-span all higher, but price is higher, and the hydraulic moving gear motor that it and one-level planetary reducer constitute is still immature technically.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, and is easy to use, reliable, stable performance, and the hydraulic pressure shell that is used for coal mine machinery that cost is low changes gear motor.
The purpose of this utility model is finished by following technical solution, it is mainly combined by oil hydraulic motor and planetary reducer, described oil hydraulic motor links to each other with the primary centre wheel by female splined shaft, and the primary centre wheel links to each other with the gear box casing of primary planet carrier with output speed and power by one-level planet wheel, the little axle of planet.
On left frame, and gear box casing and the capping of one-level gear are one by screw to described primary planet carrier by screw.
Be fixed with two bearings that radial force is big by the hole with snap ring on described gear box casing and the left frame.
Described left frame and gear box casing seal by floating sealing ring, and it is reliable, safety, and resistance to soiling is good, is specially adapted to the colliery operation of work under bad environment.
Oil hydraulic motor described in the utility model and speed reducer respectively are one, and compact again combines, and have effectively increased the convenience of maintenance, and be convenient to standardization, it has makes simply reliable in structure, stable performance, characteristics such as cost is lower have effectively satisfied the demand of Chinese market.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing, the utility model is mainly combined by oil hydraulic motor 1 and planetary reducer, described oil hydraulic motor 1 links to each other with primary centre wheel 3 by female splined shaft, primary centre wheel 3 is by one-level planet wheel 8, the little axle 9 of planet and primary planet carrier 11, by gear box casing 5 output speeds and power.Described primary planet carrier 11 is fixed on the left frame 2 by screw 12, and gear box casing 5 and one-level gear capping 10 are fixed as one.Be fixed with two bearings 6 that radial force is big by the hole with snap ring 7 on described gear box casing 5 and the left frame 2.At least seal by a floating sealing ring 4 between gear box casing 5 described in the utility model and the left frame 2, it is reliable, safety, and resistance to soiling is good, is specially adapted to the colliery operation of work under bad environment.
The utility model has adopted the SAI motor of low-speed big as the oil hydraulic motor part; The planetary reducer part can adopt one-level also can adopt the two-stage planetary reduction gear according to use condition.
Working principle is as follows:
Oil hydraulic motor 1 links to each other with primary centre wheel 3 by female splined shaft, and primary centre wheel 3 is by one-level planet wheel 8, the little axle 9 of planet and primary planet carrier 11, by gear box casing 5 output speeds and power.Described primary planet carrier 11 is fixed on the left frame 2 by screw 12, and gear box casing 5 and one-level gear capping 10 are fixed as one.Be fixed with two bearings 6 that radial force is big by the hole with snap ring 7 on described gear box casing 5 and the left frame 2.
Whole power transmission procedure structure compactness, power transmission is than big.Two big bearings 6 of radial force are fixed on gear box casing 5 and the left frame 2 with snap ring 7 by the hole.Bearing is back-to-back to put together, and has both guaranteed concentricity, reduced amount of deflection again, and support force is big; And the hole with snap ring 7 can about offset axial force.
