Does the installation form of ZQH series cylindrical gear reducer affect the model specifications?

The installation form of the ZQH series cylindrical gear reducer will not affect its core model specifications, but will be reflected in the complete mark of the model and determine the external interface size of the reducer.

Simply put, the "size" and "deceleration capacity" of the reducer are determined by its center distance and transmission ratio, and the installation form determines "how it is connected and fixed."

1. Model mark analysis

A complete ZQH reducer model usually consists of multiple parts, and the installation form is one of them. Take ZQH100-20-II-Z as an example:

ZQH: series code, representing single arc cylindrical gear reducer.

100: Total center distance, unit is millimeter (mm). This number is the most important parameter that determines the overall dimensions and specifications of the reducer (such as length, width, height, and weight).

20: Nominal transmission ratio, representing the deceleration ability of the reducer.

II: Assembly form, represented by Roman numerals, there are many types (such as I, II, III, etc.), which determines the relative position and orientation of the input shaft and output shaft.

Z: Output shaft form, which means the output shaft has a cylindrical shaft end. In addition, there are gear type shaft ends (C, CA), cross slider shaft ends (F), etc.

It can be seen from the mark that the installation form (assembly form + shaft output form) is an integral part of the model, but it is selected based on actual use needs after the core specifications (center distance, transmission ratio) are determined.

2. Influence of installation form

Choosing different installation forms will mainly affect the following external interface dimensions. After the total center distance of the reducer is determined, these dimensions will have corresponding standard values ​​depending on the installation form:

Anchor bolt holes: hole spacing (S1, S2), hole diameter (d) and number of holes (n) of the mounting holes.

Shaft end dimensions: shaft diameter (d), shaft length (L), keyway dimensions (b, t), etc. of the output shaft and input shaft.

Overall Dimensions: the total length (L), total width (B), total height (H), etc. of the reducer.
