The ZQD series reducer features high-ratio cylindrical gear reducers. It builds upon the classic ZQ series two-stage reducer by adding a first stage, resulting in a three-stage transmission. This design significantly expands the reducer's ratio range while maintaining the same basic operating conditions and assembly configuration as the ZQ series.
ZQD Series High-Ratio Reducers
Description
The ZQD series reducer features high-ratio cylindrical gear reducers. It builds upon the classic ZQ series two-stage reducer by adding a first stage, resulting in a three-stage transmission. This design significantly expands the reducer's ratio range while maintaining the same basic operating conditions and assembly configuration as the ZQ series.
The core difference between ZQD and ZQ series
Comparative Dimensions | ZQ Series Reducers | ZQD Series Reducers |
Transmission Stages and Structure | Basic two-stage transmission reducer | Adding one stage to the ZQ, creating a three-stage transmission |
Core Goals and Speed Ratio | Provides a medium range of transmission ratios, such as 8, 10, and 12.5 nominal ratios. | Designed specifically for high speed ratios, it significantly expands the transmission ratio range, for example, with nominal ratios from 63 to 315. |
Model Identification Features | Model numbers are typically in the format "ZQ-center distance-gear ratio," for example, ZQ-500-40-II-C. | There are two common model identification formats: 1. "ZQ center distance + additional stage center distance," for example, ZQ1000+250-2-4. 2. "ZQD center distance," for example, ZQD1000. |
Structural Variants | Based on the ZQ type, the ZQH type was developed, replacing the involute gears with circular arc gears, and the ZQA type, featuring improved gear materials. | Depending on the location of the added high-speed stage, the housing structure can be differentiated into inclined split surfaces (high-speed stage at the top) or flat bottom structures (high-speed stage at the bottom). |
