Abstract
The utility model relates to a roller support assembly of a high-horsepower crawler-type tractor hoist, which is formed by connecting a roller support with a reduction box assembly, wherein the reduction box assembly is divided into a reduction box, an upper shield and a power output shaft end cover; the lower part of the reduction box is provided with a magnet drain plug; the outer side of the reduction box is provided with an oil filling port cover, the power output shaft end cover and an intermediate shaft end cover; and the upper part of the upper shield is provided with a vent cap. By adopting the roller support assembly, outside media such as dust and the like can be effectively avoided intruding into a gear transmission system, and the gear transmission system of the roller support is well lubricated, and therefore, the service life of a gear is prolonged.
Description
Technical field
The utility model relates to a kind of high-power crawler type tractor hoist rolling stand assembly, relates in particular to a kind of employing Shut form Gear Transmission high-power crawler type tractor hoist rolling stand assembly.
Background technology
At present, known domestic and international high-power crawler type tractor hoist rolling stand assembly all adopts the exposed gear transmission.Adopt the exposed gear transmission, extraneous medium such as dust etc. are easily invaded gear train assembly, cause lubricant pollution, cause insufficient lubrication, and the gear teeth are easy to generate abrasive wear, reduce service life of gear.
The utility model content
Technical problem to be solved in the utility model is, overcome existing high-power crawler type tractor hoist rolling stand assembly and adopt the exposed gear transmission can't avoid extraneous medium to invade the deficiency of gear train assembly, the utility model proposes a kind of employing Shut form Gear Transmission high-power crawler type tractor hoist rolling stand assembly.
In order to address the above problem the technical solution of the utility model is such:
A kind of high-power crawler type tractor hoist rolling stand assembly, the rolling stand assembly is formed by connecting by rolling stand and reduction box assembly, it is characterized in that, the reduction box assembly comprises reduction box and last cover, reduction box is connected with bolt with last cover, and the rolling stand gear train assembly is completely enclosed within one by in reduction box and the last hood-shaped closed chamber that becomes.
Filler cap is installed in the reduction box outside, and lubrication oil is annotated in reduction box from the oil filler of filler cap.
The magnet bleeder plug is installed in the reduction box bottom, the iron filings impurity in the magnet bleeder plug adsorpting lubrication oil in the rolling stand gear train assembly, and when maintaining or/and changing oil, pollutants such as iron filings impurity are discharged from magnet bleeder plug installing hole.
Power input shaft end cap and jackshaft end cap are installed in the reduction box outside, abat-vent is installed on last cover top, the work of rolling stand gear train assembly reaches in the process of thermal equilibrium temperature, lubricating oil temperature rises to from operating ambient temperature that volume increases the process of work equilibrium temperature, and reduction box flows out by abat-vent with the air that the last hood-shaped airtight inner chamber top that becomes is sealed; Drop to from the work equilibrium temperature at lubricating oil temperature that volume reduces the process of operating ambient temperature, air flows into reduction box and the last hood-shaped airtight inner chamber top that becomes by abat-vent.
The beneficial effects of the utility model are, can effectively avoid extraneous medium such as dust etc. to invade gear train assembly, and the rolling stand gear train assembly is lubricated good, improves service life of gear.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of high-power crawler type tractor hoist rolling stand assembly described in the utility model.
Fig. 2 is a reduction box assembly schematic diagram described in the utility model.
Among the figure: 1. reduction box, 2. on cover, 3. abat-vent, 4. power output shaft end cap, 5. filler cap, 6. magnet bleeder plug, 7. power input shaft end cap, 8. jackshaft end cap, 9. rolling stand, 12. bolts.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
In Fig. 1, the rolling stand assembly is formed by connecting by bolt by reduction box 1 assembly and rolling stand 9.
In Fig. 2, the reduction box assembly be divided into reduction box 1, on cover 2, power output shaft end cap 4, reduction box 1 is connected with last cover 2 usefulness bolts 12, the rolling stand gear train assembly is completely enclosed within the closed chamber that is formed by reduction box 1 and last cover 2.
Abat-vent 3 is installed on last cover 2 tops, rolling stand 9 gear train assembly work reach in the process of thermal equilibrium temperature, lubricating oil temperature rises to from operating ambient temperature that volume increases the process of work equilibrium temperature, and the air that the airtight inner chamber top that reduction box 1 and last cover 2 form is sealed flows out by abat-vent 3; Drop to from the work equilibrium temperature at lubricating oil temperature that volume reduces the process of operating ambient temperature, air flows into the airtight inner chamber top that reduction boxes 1 and last cover 2 form by abat-vent 3.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
