減速器的種類繁多，按照傳動類型可分為齒輪減速器、蝸桿減速器和行星齒輪減速器；按照傳動級數(shù)不同可分為單級和多級減速器；按照齒輪形狀可分為圓柱齒輪減速器、圓錐齒輪減速器和圓錐－圓柱齒輪減速器；以便根據(jù)使用者的不同要求（使用場所，是否無人操作，是否在城區(qū)內(nèi)，地上、地下建筑物有無特定要求，是否有噪聲防護，或無其他特定要求）去滿足。按照傳動的布置形式又可分為展開式、分流式和同軸式減速器。

There are many types of reducer according to transmission type can be divided into gear reducer, worm reducer and planetary gear reducer; according to transmission series can be divided into single and multi-stage gear reducer; according to the shape can be divided into cylindrical gear reducer, bevel gear reducer and cone - cylindrical gear reducer; according to the arrangement the form of transmission can be divided into expansion, split and coaxial reducer.

減速機與工作機的聯(lián)接：減速機直接套裝在工作機主軸上，當減速機運轉(zhuǎn)時，作用在減速機箱體上的反力矩，又安裝在減速機箱體上的反力矩支架或由其他方法來平衡。機直接相配，另一端與固定支架聯(lián)接.

The connection between the reducer and the working machine: the reducer is directly installed on the main shaft of the machine, when the reducer operates, the torque acting on the gearbox body is installed on the reverse torque support on the reduction box body or by other methods to balance. The machine is directly matched and the other end is connected with the fixed support.

允許輸入法蘭：

不能大于或小于臨級減速機的標準尺寸，如減速機PLE80?的標準法蘭為80mm,其臨級的減速級是PLE60?和PLE120，PLE80?允許法蘭不應小于60mm,也不能大于120mm。

Allow input flange

It can't be greater than or less than the standard  of the reducer. For example, the standard flange of reducer PLE80 is 80mm, and the deceleration stage of its reducer is PLE60? PLE120, PLE80?所有緊力螺栓均需用力矩板手按標明的固定扭力矩數(shù)據(jù)進行固定和檢查。 The maximum allowable flange should not be less than 60mm, nor greater than 120mm.
