The invention discloses an oil level gauge and a gear box, which includes an oil level detection rod and a breathing cover located at the top of the oil level detection rod, and the oil level detection rod includes an oil level detection part at the lower end and a fixing part at the upper end , the fixing part is used to fix the oil level detection rod on the gear box, a cavity is formed between the breathing cover and the oil level detection rod, and a cavity is opened in the fixing part through the inside of the gear case and the The breathing channel of the cavity, the side wall of the breathing mask is provided with a through hole penetrating the inner cavity and the external environment. The oil level gauge of the present invention is simple in structure, easy to install, integrates the functions of oil level height measurement, gearbox pressure difference balance and oil sampling, greatly simplifies the peripheral structure of the gearbox, and reduces the installation environment requirements of the gearbox. It is especially beneficial to the post-maintenance of the gearbox for rail transit.
Description
technical field [0001] The invention relates to the technical field of straddle monorail train driving, in particular to an oil level gauge of a gear box and the gear box. Background technique [0002] In the straddle-type single-rail drive gearbox or other gearboxes, gears and bearings need to have enough lubricating oil for splash lubrication, and the amount of lubricating oil is directly related to the wear of the gears and the temperature rise of the bearings. But with the operation of the gearbox, the lubricating oil is gradually consumed, so it is necessary to use a device that can detect the amount of oil in the box. [0003] Due to the limited position of the straddle-type monorail drive gearbox or other gearboxes, it is impossible to arrange the sight glass for ordinary rail transit, and only the oil level gauge can be used to detect the oil level. Due to the high transmission speed of the gear, the air pressure in the box is large and unevenly distributed, which m...
