上海正堂021-61495699 是专业生产HB大功率齿轮减速机的厂家，是集研发，生产，销售于一体的减速机集团；
HB斜齿/伞齿系列大功率减速机是全新型硬齿面减速机，具有大转矩范围，采用单元结构模块化设计可卧式安装也可立式安装。有实心轴、空心轴和收缩盘空心轴输出。应用范围广。
采用高强度优质合金钢渗碳游淬火，具有高效率高寿命齿轮及高许用轴向，径向载荷，运行噪音低，可靠性高，结构紧凑等优点。
H系列经过正堂减速机改造有如下创新：
1.零部件种类减少而规格数量增多
2.传动功率增大，运转可靠性提高
3.可以采用性能优异的非接触式和耐磨的迷宫式密封装置
4.可以提供适于狭小空间安装的法兰轴
5.采用mssak计算机程序设计吸收噪音的箱体结构
6.实现特大的齿面接触比
7.增大了风扇和新型的导流系统
8.增大了箱体的表面积
9.采用圆锥齿轮削磨工艺
10.模块化单元结构
具体如下型号：
