一、概述液压马达的输出扭矩是评定液压马达性能的主要指标。一般用理论扭矩T_(thmi)、运转扭矩T和起动扭矩T_s表示液压马达的扭矩性能。T_(thmi)=1.59q△p,因为瞬时排量是个变值,所以T_(thmi)是理论扭矩的平均值。T和T;是液压马达的实际测定值,由于有容积损失和机械损失,它们都小于T_(thmi)值。

First, an overview of the hydraulic motor output torque is to assess the performance of the main indicators of the hydraulic motor. The torque performance of the hydraulic motor is generally expressed by the theoretical torque T_ (thmi), the operating torque T and the starting torque T_s. T_ (thmi) = 1.59q △ p, because the instantaneous displacement is a variable, so T_ (thmi) is the average theoretical torque. T and T; are the actual measured values ​​for the hydraulic motor and they are all less than the value of T thmi because of volume losses and mechanical losses.
