ZJY型轴装式圆柱齿轮减速器
Type ZJY Shaft Assembly Cylindrical Gear decelerators
概述Brief
ZJY系列轴装式减速器采用直接悬挂在配套主机动力输入轴上的安装方式，省略了两者间的联接附件和减速器安装平台，适用于半式提升机，皮带输送机、刮板输送机等设备的机械传动，也可与其他有此安装要求的主机配套。
产品按ZBJ19009-88标准制造。主要传动零件采用优质合金钢材质。齿轮经渗碳淬火磨齿工艺加工，精度为(GB10095-88)6级。产品体积小，承载能力高，寿命长，噪音低，效率高。与ZJ系列轴装和减速器比较，相同的输出扭矩，ZJY重量只有ZJ的30%左右，因而对配套主机的机架刚性要求大大下降，传动平衡。
产品除可双向运转外，可以根据用户需要配置逆止装置，实现单向制动。
Series ZJY shaft assembly decelertor is mounted directly in a way of hanging on the dynamic input shaft of matching master machine, which dispenses with the connecting accessory and decelerator erection platform. It is applicable for the mechanical drive of bucket elevator，belt conveyor, and flight conveyor, as well as matching with other similar master machine.
The product is manufactured according to ZBJI9009 -88 standard, and main drive components are made of quality alloy steels. Gar wheel is processed with carburizing and quenching and grinding teeth with precision of Class (GB10095-88) 6. The product is compact size with high carrying capacity, long service life, low noise, and high efficiency. ZJY has the same output torgue as that of ZJ shaft assemblage decelerator. ZJY weights only 30% weight of ZJ, therefore, the rigidity required for the master machine frame is significantly decreased, and ZJY dreves stable.
Not only can this product be operated bouble direction, but also it can be equipped with antirunback device to achieve oneway braking.
二、减速器的型号与标记Type and symbol of decelerator
全系列减速器以低速级中心距(mm)为单位，共有75、90、106、125、150、 180 、212、250、 300 九种规格。每一规格的传动比有10、11.2、 12.5、 14、16、 18、 20、22.4、25九种。
减速器的标记代号中包括型号，低速级中心距、公称传动比和旋向。
The unit for the complete series decelerator is low-speed class center distance (mm),in total 9 specs of 75, 90106,125, 150,and 300 each specs has 9 drive ratios of 10、11.2、12、5、14、16、 18、20、22.4、and 25.
Decelerator earmark is composed of type, low-speed class center distance,nominal
drive ratio and direction of rotation.

五、减速器的选用Decelerator selection
减速器的选用Decelerator selection
(1)查“减速 器载荷分类”表，确定载荷类型。
Identify load type from tableof“ Decelerator load classification" .
注。U为均匀载荷，M为中等冲击载荷，H为强冲击载荷。
Note:U for unifom load, M for middle impact load, H for heavy impact load.
