Problems solved by technology

However, the problem with the use of the tensioner is that when the belt tensioner is running, the vibration of the running belt may excite vibrations in the tension spring
These vibrations are undesirable as they cause premature belt and tensioner wear

Abstract

The invention discloses an automatic tractor belt tension controller, which comprises a rotation oil cylinder driving mechanism, a tension pulley lever mechanism and a set of link mechanism for implementing drive. The rotation oil cylinder driving mechanism comprises a rotation oil cylinder and a coupling, and can drive a rotary shaft to rotate by a fixed angle, and the tension pulley lever mechanism comprises a tension pulley, a lever and a spring, and can pull up the spring to move down the tension pulley, so that belt wheel tensioning is realized. The link mechanism comprises five movable components, all the components are articulated, and can turn to pull the spring, and meanwhile, the link mechanism has a self-locking function. The automatic tractor belt tension controller can position the tension pulley by controlling the oil cylinder and a step motor.

Description

technical field [0001] The invention relates to the field of electromechanical control, in particular to an automatic control device for tractor belt tension. Background technique [0002] The tractor belt tensioning automatic control device is a new type of positioning device that can automatically control the position of the belt tensioning wheel developed by combining electronic technology and mechanical technology to meet the needs of agricultural tractor belt transmission. It can not only realize the positioning and self-locking of the tensioning wheel on the mechanism, but also realize the tension control of the belt drive and the self-locking of the position of the tensioning wheel by using its own controllable power device at the tractor driving operation position. [0003] The tensioner positioning device is a tensioning device for belt transmission. In order to maintain proper belt tension to avoid belt slippage, compensate for belt wear and elongation caused by ag...
