Abstract

The paper touches upon the issue of spatial hinge mechanisms with a special structure, developed on the basis of Bennett’s spatial four-bar linkage. The interest in the study of such mechanisms and their use in technology is constantly growing, since they are distinguished by a high efficiency, the transmission accuracy of motion law, the rigidity of the structure and the ability to transfer high loads. In addition, the hinges of the mechanisms are represented only by rotating pairs, which in the design of the hinge units allows the use of rolling bearings and reliably isolate the units from the external environment. The authors give several areas of application of mechanisms as basic and independent devices in technology, including the agro-industrial complex.

Highlights

Spatial mechanisms are widely used in various branches of technology: appliances, textile technology, airplanes, tractors, automobiles and so on, but they are especially used in agricultural machines
It is necessary to say that spatial mechanisms with rotational pairs received their start in life due to the scientists of the Department of Theory of Mechanisms and Machines of Kazan State Agrarian University, whose developments are priority at national and international levels
We briefly describe the main types of devices, grouped by types of technology based on spatial mechanisms

Summary

Introduction

Spatial mechanisms are widely used in various branches of technology: appliances, textile technology, airplanes, tractors, automobiles and so on, but they are especially used in agricultural machines. The academician V.P. Goryachkin wrote: “Spatial mechanisms are not developed enough so far, since they are relatively rarely used, but their use in agricultural machines and implements is very wide (mowers, reapers, sheaves, rakes, tedders, plows)” [1]. It is necessary to note that V.P. Goryachkin was the first in Russia to study the theory of spatial mechanisms, who performed in 1914 a kinematic and force analysis of a reaping machine rake. Goryachkin was the first in Russia to study the theory of spatial mechanisms, who performed in 1914 a kinematic and force analysis of a reaping machine rake In his fundamental work «Agricultural Mechanics », he devoted a separate paragraph to these mechanisms. The schemes using four-, five- and six-bar mechanisms are gave been implemented
