Secondary speed reduction box applied on agricultural irrigation driving equipment

Abstract

The invention provides a secondary speed reduction box applied on agricultural irrigation driving equipment, which belongs to the technical field of machinery and solves the problems of low transmission efficiency and large size of an existing secondary speed reduction box. The secondary speed reduction box applied on the agricultural irrigation driving equipment comprises a worm gear box and a rotary shaft, a worm gear and a worm are mounted in the worm gear box, an oil storage cavity used for storing lubricating oil is arranged in the worm gear box, two bearings are sleeved at two ends of the worm respectively and two ends of the worm penetrate through the worm gear box, the two bearings are fixedly mounted on the inner wall of the worm gear box, the worm gear is sleeved on the rotary shaft through a circumferential limit structure, an output end of the rotary shaft is fixedly connected with a connecting disc used for being connected with a hub, and the worm gear and the worm are connected through a planar secondary enveloping ring-surface worm pair. The secondary speed reduction box has the advantages of high transmission efficiency, stable transmission, long service life and small size.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a two-stage reduction box, in particular to a two-stage reduction box applied to agricultural irrigation drive equipment. Background technique [0002] The two-stage reduction box in the driving device of agricultural irrigation driving equipment currently used in the market generally includes a worm gear box, and a worm wheel and a worm are installed in the worm gear box, and the worm wheel and the worm are engaged and connected. One end of the worm is connected to the output shaft of the motor. connection, the worm wheel is sleeved with a rotating shaft, and the output end of the rotating shaft is fixedly connected with a connection plate and connected to the hub through the connection plate. There is an oil storage chamber between the worm wheel and the worm. The existing problem is: The Archimedes worm gear pair is used for transmission, and its transmission efficiency is low,...

Problems solved by technology

[0002] The two-stage reduction box in the driving device of agricultural irrigation driving equipment currently used in the market generally includes a worm gear box, and a worm gear and a worm are installed in the worm gear box, and the worm gear and the worm are meshed and connected, and one end of the worm is connected to the output shaft of the motor. connection, the worm wheel is sleeved with a rotating shaft, and the output end of the rotating shaft is fixedly connected with a connection plate and connected to the hub through the connection plate. There is an oil storage chamber between the worm wheel and the worm. The existing problem is: The Archimedes worm gear pair is used for transmission, and its transmission efficiency is low, only 40%. At the same time, this kind of transmission makes the volume of the worm gear box large, causing the entire worm gear box to occupy a large area.
