A general transposition gear reducer and its reversing method

Abstract

The invention discloses a universal transposition gear speed reducer, aims to solve the technical problem that the output power of power chassis (machine heads) of riding type rice transplanters of different forms is not matched with the operation power required by rice seeding machines (machine tools), and belongs to the technical field of rice seeding machines. The universal transposition gear speed reducer is characterized in that one end of an input gear shaft is linked with a machine head transmission shaft; a conical gear at the other end of the input gear shaft is in meshed connection with a bevel gear; one end of an output shaft in a gear box is fixedly connected with a bevel gear key; the end part of the other end of the output shaft extends outwards through a center hole in a first end cover, and is fixedly connected with an output gear key; an output gear is in linked connection with a transmission shaft of the machine tool. The universal transposition gear speed reducer is simple in structure, is provided with a small number of parts, and is universal; the assembling position of the bevel gear and the direction of the extension segment of the output shaft can be changed, so that switching of four forms of the gear speed reducer can be realized easily, the machine tool can be matched with various machine heads of different models, great convenience is brought to the production of manufacturers, and different requirements of users can be met.

Description

technical field [0001] Rice paddy field seeding machinery is used in conjunction with a variety of ride-on rice transplanter power chassis. The invention is a universal transposition gear reducer, which is used to convert the output power of different types of ride-on rice transplanter power chassis (machine head) to the working power required by rice paddy field sowing machinery (tools), and belongs to rice paddy field sowing machinery technology field. Background technique [0002] The ride-on rice transplanter has been popularized all over the country for many years, and now it has a huge stock in the country. The power chassis used by the ride-on rice transplanter is a mature power system for paddy field operations. In recent years, in order to realize the mechanization of rice planting, a variety of rice paddy field sowing machines (hereinafter referred to as machines) have been developed across the country, and most of them are used in conjunction with the power chass...

Problems solved by technology

However, due to the lack of uniform standards for the machine head and the diversity of types; it is difficult to ensure the accuracy of the investigation of the machine head type before the machine tool is sold, often resulting in the machine tool not being able to match the machine head on site

In mass production, the above-mentioned dedicated gear reducers still cannot meet the actual needs
