Dual-zone type interlayer box body air cooling planetary reduction gearbox

Abstract

The invention relates to the technical field of planets, in particular to a dual-zone type interlayer box body air cooling planetary reduction gearbox. The dual-zone type interlayer box body air cooling planetary reduction gearbox comprises a machine base, an inner cylinder and transmission elements. The transmission elements comprise an input shaft, an output shaft, a sun wheel, a planet wheel, an inner tooth ring and a planet frame. The dual-zone type interlayer box body air cooling planetary reduction gearbox is characterized in that the inner cylinder is a dual-zone type thin-wall cylinder and comprises a meshing zone and a non-meshing zone; the non-meshing zone is placed outside the machine base; the inner surface of the machine base is connected with the outer surface of the meshing zone to form an airtight interlayer in an enclosed mode; the top of the machine base is provided with an air inlet; the bottom of the machine base is provided with an air outlet; the inner tooth ring is arranged in the input end of the meshing zone; an oil pool forms a fall in the position where the meshing zone is connected with the non-meshing zone; a cavity is formed by the end face of an inner end cover and the inner surface of the non-meshing zone; the top of the non-meshing zone is provided with a labyrinth type vent hood; an outlet in the bottom of the non-meshing zone is provided with a magnet; the top of the machine base is provided with a digital display thermodetector. The dual-zone type interlayer box body air cooling planetary reduction gearbox has the beneficial effects that scrap iron impurities in oil 'slip' from the part, in the meshing zone, of the oil pool into the part, in the non-meshing zone, of the oil pool; the vent hood ensures the balance of the pressure inside a box body and outside the box body; the airtight interlayer is simple in structure and low in cost; the thermodetector displays the temperature of the oil rapidly at any time.

Description

AI Technical Summary

Problems solved by technology

[0008] Obviously, the volume of the oil pool in the background technology is smaller than that of the original technology without interlayers, and the amount of lubricating oil is therefore less. When the iron powder impurities mixed in the lubricating oil gradually increase, the background technology has no technical solution for reducing the iron powder impurities. As a result, the oil quality decreases, the oil temperature rises, the oil viscosity becomes thinner, and the oil film is damaged, which leads to a decrease in the thermal power of the reducer and a shortened service life;

[0009] (2) During operation, it is impossible to check the oil temperature of the lubricating oil in the transmission box:

Since the change of airflow temperature cannot really change the lubricating oil in the gearbox, it is most important to directly understand the oil temperature and control the oil temperature, but the background technology includes the existing technology, the measuring rod of the electronic digital display thermometer in operation It can't be inserted at all, so there are no oil temperature gauges in the existing general-purpose models;

[0011] (3) The quality change and oil storage capacity of the lubricating oil in the transmission box are not easy to check, and it is also inconvenient to refuel
