Engine belt tensioning adjusting mechanism

Abstract

The invention discloses an engine belt tensioning adjusting mechanism. The mechanism comprises a fixing plate; a long kidney-shaped through groove is formed in the fixing plate; an adjusting shaft is arranged in the through groove of the fixing plate; the front shaft end of the adjusting shaft penetrates through the through groove and can slide in the length direction of the through groove with the inner wall of the through groove as a guide; the rear shaft end of the adjusting shaft is arranged to be a feed screw nut with an internal thread structure; an adjusting screw rod in threaded fit with the feed screw nut of the adjusting shaft is arranged on the front surface of the fixing plate by utilizing an L-shaped connecting plate, a rotary hand wheel is arranged at one end of the adjusting screw rod and is used for driving the adjusting screw rod to rotate so as to enable feed the screw nut to move in the length direction of the through groove, and therefore the position of the adjusting shaft in the length direction of the through groove can be adjusted; and the front shaft end of the adjusting shaft is linked with a tensioning wheel, and therefore the tensioning degree of a belt can be adjusted. The engine belt tensioning adjusting mechanism has the advantages that the tensioning degree of the belt can be accurately adjusted, and the working quality of the engine can be ensured.

Description

technical field [0001] The invention relates to an engine belt tension adjustment mechanism, more specifically a belt tension adjustment mechanism used in the installation and maintenance of various engine pulley structures. Background technique [0002] Engine pulley drive is a relatively common structure. The belt used in the pulley drive structure has a certain degree of elasticity. After a period of use, the belt’s elasticity decreases and the length of the belt becomes longer. If the position of the driving wheel and the driven wheel is not correct If the belt is changed, the belt will become looser and looser, which will affect the power transmission efficiency. Therefore, after a period of use, it is necessary to tighten the loose belt to the correct position again. [0003] In the prior art, the conventional way is for the operator to use the steel pipe to pry the position of the tensioner to tighten the belt between the tensioner and the driving pulley. In this way...

Problems solved by technology

[0003] In the prior art, the conventional way is for the operator to use the steel pipe to pry the position of the tensioner to tighten the belt between the tensioner and the driving pulley. In this way, the adjustment of the position of the tensioner depends on the operator If the force is too large and the distance between the tensioner wheel and the driving wheel is too large, the belt will be too tight and cause breakage, but if the force is insufficient, the adjustment is not in place, and the distance between the tensioner wheel and the driving wheel is too small, then Because the belt is too loose, there will still be slippage. For this reason, the operator needs to repeatedly debug, the process is cumbersome, the work intensity is high, and the efficiency is low; the debugging work depends on the work experience of the debugger, and the effect is difficult to control
