行星减速机伺服系统变频器采用矢量控制方式时伺服电机输出转矩可通过转矩电流分量控制,因此,速度调节时可使用转矩限制功能。转知限制功能可用于传送带卷取设备等的控制,以防止伺服电机转矩 过大引起的机械部件损坏。
转矩限制对加减速同样有效,它可能会延长加减速和速度调节时间;对于升降负载控制,如转矩限制值设定过小,可能存在重力自落的危险,使用时必须引起注意。
行星减速机伺服系统变频器可对不同的运行状态,如正/反转、运行/制动等,设定不同的转矩限制值;限制值可用参数或AI给定,行星减速机伺服系统变频器与转矩限制相关的参数。
行星减速机伺服系统变频器有正转运行、正转制动、反转运行、反转制动4种工作状态,其输出特性分别为第1一第4象限,不同象限的转矩限制值按如下原则确定。

与其他的砂处理设备不一样,喷砂机是一种能使用磨料借助压缩空气动力,喷射到工件表面的一种砂处理设备。根据喷砂机的特点,喷砂机适用于清理锻铸件、冲压件及机械加工件的粗糙表面、用于喷涂、电镀前的预处理工序、强化光饰零件表面,喷砂机特别适合于中、小零件单件小批量生产。喷砂机的特点是设有进气压力、喷砂压力显示,并装有减压阀,可以根据需要调节喷砂压力。在压缩空气进口装有过滤器,以滤去压缩空气中的水分。喷砂机配备自动分离和自动除尘系统,使用过的砂料被负压从机器的底部输送到旋风分离器中进行分离,将喷砂过程中产生的粉尘、锈质、氧化皮等杂质从好的砂料中分离出来。

2、箱体
箱体是减速器的重要组成部件。它是传动零件的基座,应具有足够的强度和刚度。
箱体通常用灰铸铁制造,对于重载或有冲击载荷的减速器也可以采用铸钢箱体。单体生产的减速器,为了简化工艺、降低成本,可采用钢板焊接的箱体。
灰铸铁具有很好的铸造性能和减振性能。为了便于轴系部件的安装和拆卸,箱体制成沿轴心线水平剖分式。上箱盖和下箱体用螺栓联接成一体。轴承座的联接螺栓应尽量靠近轴承座孔,而轴承座旁的凸台,应具有足够的承托面,以便放置联接螺栓,并保证旋紧螺栓时需要的扳手空间。为保证箱体具有足够的刚度,在轴承孔附近加支撑肋。为保证减速器安置在基础上的稳定性并尽可能减少箱体底座平面的机械加工面积,箱体底座一般不采用完整的平面。
