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;
[0011] (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. It is difficult to remove the heavy motor and reducer, so repair and maintenance are difficult, and the cap on the top of the motor is difficult to waterproof. more difficult to dust
[0012] (1) On April 26, 2006, a pile driver suddenly collapsed in a construction site on Xiangheyuan Road outside Dongzhimen, Beijing, causing the death of two workers

Embodiment Construction

[0034] The present invention is described in detail below in conjunction with accompanying drawing:

[0035] refer to figure 1 and 2 .An oil temperature alarm planetary-hypocycloid four-ring sheet pile machine reducer, including a box body 1, a motor 3 symmetrical on both sides, a cover plate 9 and transmission parts in the box body 1. The transmission parts include ring plates, eccentric Bearing, hypocycloid ring gear 14 and cycloid wheel 11, the ring plate is four identical ring plates 8, there are symmetrical bearing holes on both sides of the center hole of ring plate 8, and the hypocycloid ring gear 14 is connected to the ring plate 8 central holes, characterized by:

[0036] Described box body 1 is provided with oil temperature sensor G, and oil temperature sensor G is like people's eyes clear, watching the change of oil temperature in the gear box of more than ten meters height all the time. The oil temperature is a very important factor for the normal operation of t...

Abstract

The invention relates to the technical field of pile machine speed reduction, in particular to an oil-temperature alarm planet-hypocycloid four-ring plate reducer for a pile machine. The reducer comprises a box body, motors, cover plates and transmission pieces. The transmission pieces comprise eccentric bearings, ring plates, hypocycloid tooth rings and cycloidal gears. The hypocycloid tooth rings are assembled in the centers of the ring plates. The oil-temperature alarm planet-hypocycloid four-ring plate reducer is characterized in that an oil temperature sensor is arranged in the box body, labyrinth type ventilation hoods are arranged on the cover plates, and the motors are inversely arranged below the box body; the motors are connected with NGW reducers through shafts; the eight eccentric bearings are arranged on output shafts of the two NGW reducers respectively, and the eccentric bearings comprise rolling bearing bodies and eccentric sleeves; in the four eccentric sleeves, the phase difference of the first eccentric sleeve and the second eccentric sleeve is 180 degrees, the phase difference of the third eccentric sleeve and the fourth eccentric sleeve is 180 degrees, and the phases of the second eccentric sleeve and the third eccentric sleeve are the same; the eccentric sleeves are supported on thrust bearings, and the cycloidal gears are connected with a main cylinder; and the main cylinder is supported in the box body through bearings and connected with a drill rod and a flange. The oil-temperature alarm planet-hypocycloid four-ring plate reducer has the beneficial effects that the dynamic state of the reducer is known according to the oil temperature, the air pressure in the box body and the air pressure outside the box body are kept balanced through the ventilation hoods, and the accident rate is reduced through the inverse arrangement of the motors so that four-electrode motors can replace six-electrode motors for NGW speed reduction so as to reduce the cost.

Description

【Technical field】 [0001] The invention relates to the technical field of pile machine deceleration, and relates to an oil temperature alarm planetary-hypocycloid four-ring sheet pile machine reducer. 【Background technique】 [0002] With the rapid development of my country's economy, construction machinery has been widely used. As a basic construction, long screw pile machines are scattered all over the world, so that 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) [0003] Background technology: China Patent Office has published the following patents successively: [0004] (1) Power head of screw pile machine (201020300223.7) ...
