GROBbevel gear high-speed screw jacks work in
any position and can be fixed on all sides due to the
cubic housing shape.
The range includes three installation sizes and 2 versions
(Basic Version & Travelling Nut version), with
transmission ratios 1:1, 2:1 and 3:1. Thanks to the
high efficiency of the bevel gear set, the total efficiency
of the GROB bevel gear high-speed screw jack
is around 75% with ballscrew spindles and around
40% with trapezoidal threaded spindles.
There are versions with one, two, three or four drive
shafts possible (for 1:1, two drive journals offset by
90° are not possible). As a result, gearbox arrangements
are possible that make the use of additional
bevel gearboxes unnecessary
An extensive range of essories is available for
the GROB bevel gear high-speed screw jack range,
which can in part be adopted from our worm gear
lifting gearbox range.
GROB斜齿轮传动高速螺旋升降机可在任何位置下工作，由于其正方形的外形结构，可以在任意一面固定。安装范围包括三种安装尺寸和二种不同类型（基本型和螺母运动型），传动速比为1:1, 2:1和3:1。由于斜齿轮传动的高效性，采用滚动丝杆，GROB斜齿轮传动高速螺旋升降机的总输出效能达到75%，采作梯形螺纹丝杆，总输出效能达到40%。GROB斜齿轮传动高速螺旋升降机有一个，二个，三个或四个传动轴四种不同型号（只能用于1:1，二个传动90°布置不可以）。所以，齿轮箱的布置可以利用其它斜齿轮箱。我们可为GROB斜齿轮传动高速螺旋升降机提供各种不同的附件，这与我们的蜗轮蜗杆提升齿轮箱的范围一样。
