Small-tooth-difference bidirectional output pile-driver speed reducer with oil temperature alarming function

Abstract

The invention relates to the technical field of speed reduction of pile drivers, in particular to a small-tooth-difference bidirectional output pile-driver speed reducer with an oil temperature alarming function. The small-tooth-difference bidirectional output pile-driver speed reducer comprises a box, motors, a cover plate and gear transmission parts and is characterized in that an oil temperature sensor is arranged in the box, and labyrinth vent hoods are arranged on the cover plate and each comprise an outer hood shell, a labyrinth shell and an exhaust pipe; the two motors are inversely connected with the lower side of the box, and shaft extension ends of the motors are connected with small-tooth-difference speed reducer bodies; the gear transmission parts comprise an outer meshing pair and an inner meshing pair; the outer meshing pair comprises a driving wheel, a distributing gear and outer teeth of a central circular ring; the inner meshing pair comprises inner teeth of the central circular ring, five quasi planet wheels and a central wheel; the central circular ring is connected with an outer sleeve, and the outer sleeve is supported in a central hole of the box through bearings; the outer sleeve is connected with a base plate, and a flange of the base plate is connected with a large sleeve of a pile driver; the central wheel is connected with an inner barrel, the inner barrel is supported in the outer sleeve through bearings, and the inner barrel is connected with a drill rod bushing. The small-tooth-difference bidirectional output pile-driver speed reducer has the beneficial effects that the dynamic state of the speed reducer can be mastered, the air pressure in the box and the air pressure outside the box are balanced, the motors are inversed to reduce the overturning moment of the pile driver, and thus the overturning accident probability is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of double-motor pile driver deceleration, and relates to a pile driver reducer with oil temperature alarm and small tooth difference bidirectional output. 【Background technique】 [0002] With the rapid development of my country's economy, construction machinery has been widely used, and the long screw pile machines used as infrastructure are scattered all over the world. As a result, the demand for pile machines has increased sharply. Said: "There is even a phenomenon of queuing up to pick up the goods at the pile driver factory with a large amount of money. The three-ring reducer manufacturer that matches the power head with the pile driver factory has increased its output so that each pile driver manufacturer can supply a complete set Goods." (See Science and Fortune, 2013.01) Background technique: [0003] (1) The invention patent of China Sunward Intelligent Equipment Co., Ltd. "Separate Drive Casing ...

AI Technical Summary

Problems solved by technology

The disadvantage of the ventilation hood (JB1130-70) is: the exhaust hole is too small (the maximum diameter of the straight hole in the box is only Φ20mm, and the small hole outside the box that is in contact with the environment is even smaller)

For the pile driver reducer, the disadvantages of the ventilation cover (JB1130-70) are even more obvious: open-air operation, large dust, and the small exhaust holes will gradually become smaller after the dust sees water, so that the ventilation cover will gradually lose the inside and outside of the box. Pressure balance, when the air pressure inside the box is greater than the air pressure outside the box, the lubricating oil will leak from the seal;

[0012] (c) Disadvantages of top-mounted dual motors: Due to the harsh working conditions on the construction site, most operators do not have maintenance equipment and skills, and the heavy motors and reducers are difficult to remove down, so it is difficult to repair and maintain, and the cap on the top of the motor is difficult to waterproof and even more difficult to prevent dust

The top-mounted dual motors have a high center of gravity and a large overturning moment, which may cause overturning accidents
