调平角度不小于1°

调平精度1"条件的楔铁式调平机构.

Abstract

For the purpose of precision levelling and accuracy maintenance under big vertical load and azimuth torque

a wedge leveller has been designed against 4 criteria based on its operating requirements

so that the static friction counteracts the azimuth torque

the increased wedge area carries the big vertical load

and the high transmission ratio and self locking of the wedge screw mechanism can be used to achieve precision levelling and accuracy maintenance. The levelling accuracy of the wedge leveller designed is 1″ when the vertical load is 15 t

the azimuth torque is 10

000 N.m

and the levelling angle is not less than 1°.
