Double-region sandwich-layer box water-cooling dynamic-balance hypocycloid reduction box

Abstract

The invention relates to the technical field of cycloids, in particular to a double-region sandwich-layer box water-cooling dynamic-balance hypocycloid reduction box. The reduction box comprises a machine base, an inner cylinder and a transmission part. The transmission part comprises an input shaft, an output shaft, a four-piece cyloidal wheel, a hypocycloid gear ring and an eccentric bearing. The reduction box is characterized in that the inner cylinder is a double-region thin-wall cylinder and comprises an engagement region and a non-engagement region arranged outside the machine base, the inner surface of the machine base and the outer surface of the engagement region are connected to form a closed sandwich layer in an enclosing mode, a water inlet and a water outlet are formed in the top and bottom of the machine base respectively, the input end of the engagement region is connected with the hypocycloid gear ring, oil pools form a drop height at the intersecting portion of the engagement region and the non-engagement region, the end face of an inner end cover and the inner surface of the non-engagement region form a cavity, and a labyrinth ventilation cover is arranged at the top of the non-engagement region. A digital display temperature measuring instrument is arranged at the top of the machine base, and a magnet is arranged at a discharging port in the bottom of the non-engagement region. The reduction box has the advantages that scrap iron impurities in oil will slide into the oil pool of the non-engagement region from the oil pool of the engagement region; the ventilation cover guarantees air pressure balance inside and outside of the box; the closed sandwich layer is simple in structure, and the cost is low; the oil temperature is displayed at any time; dynamic balance is achieved.

Description

【Technical field】 [0001] The present invention relates to the technical field of cycloid deceleration, and is an improvement of the invention patent application "Case Interlayer Water-cooled High Thermal Power Dynamic Balance Hypocycloid Reducer" (201510078976.5), a double-zone interlayer box water-cooled dynamic balance hypocycloid deceleration box. 【Background technique】 [0002] Background technology "Case Interlayer Water-cooled High Thermal Power Dynamic Balance Hypocycloid Gearbox" (201510078976.5) adopted a technical solution to solve the defect of low thermal power in the prior art: the inner wall of the box is connected with the inner cylinder and the round end cover The outer wall of the box is surrounded to form a closed interlayer. The top of the box is provided with a water inlet connected to the closed interlayer, and the side of the box is provided with a water outlet connected to the closed interlayer. According to the temperature change of the water, it is e...

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:

[0010] Background Art The temperature is controlled according to the temperature change of the cooling water. Since the change of the water temperature cannot truly reflect the change of the oil temperature of the lubricating oil in the gearbox, the most important thing is to directly understand the oil temperature and control the oil temperature. However, the background technology includes current With technology, the measuring rod of the electronic digital display oil temperature meter cannot be inserted at all during operation, so the oil temperature meter cannot be installed in various 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
