SWL蜗轮螺杆升降机JBT8809-1998

SWL Worm and Worm Wheel Lifter

一、概述Brief:

蜗轮螺杆升降机是通过蜗轮转动螺杆完成提升,下降,推进等功能,广泛应用于机械,冶金、建筑,水利、化工等各项行业,具有结构紧凑,体积小,安装方便、可靠性好, 稳定性高,使用寿命长等优点。本系列升降机可自锁,承载能力在2.51- -35t之间, ***高输入转速1500/min.工作温度在- 20'C一100"C之间。

Worm and worm wheel Liter performs moving up.down and forward by worm driving. It is widely used in field of machinery, architecture, chemistry etc. The lifer has advantages of compact structure,small size, easy installation .good roliability .high stability and long life span. It has self locking. The maximum loading capability is 2.5 to 35 ton and the miximum input RPM is 1500r/m.

The environment working temperature is botween-20'C and 100'C.

二、型式和标记Type and Earmark

2.1结构型式Structurat mode

1型一_螺杆作轴向移动 (见图1)

2型一螺杆 作旋转运动螺杆上的螺母作轴向移动(见图2)

Type1--Screw spins and rotate axially at the same time(see Figure 1)

Type--Screw spins while nut on Screwis rotating axially(see Figure 1)

2.2装配型式Assemblage mode

升降机每种结构型式又分为两种装配型式

A型一螺杆 (或螺母)向上移动(见图1和图2)

B型一-螺杆 (或螺母)向下移动(见图1和图2)

There are 2 assemblage modes available for each of elevator structural mode;

Type A--Scrow(or nut) moves upwards (see Figure 1 and Figure 2):

Type A--Screw(or nut) moves downwards (see Figure 1 and Figure 2):

2.3螺杆头部型式Screw head mode

1型结构型式的螺杆头部分为1型(圆柱型),1型(法兰型)。川型(螺纹型)和IV (扁头型)四种型式(见图1):

-2型结构型式的螺杆头部分为1型(圆柱型),川型(螺纹型)和IV (扁头型)两种型式(见图2);

-There are 4 type available for the head of screw with Type 1 structural mode:Type 1 (eylinder mode) Typell (lange mode).Type m (thread mode);and Type IV (hat head mode)(see Figure 1).

-There are 2 type available for the head of screw with Type 2 structural mode:Type 1 (cylinder mode) Typell (thread mode)

2.4传动比Drive ratio

升降机分为两种传动比,即普通(P)和慢速(M),

There are 2 drive rations avallable for elevator :comon ratio(P)and slow-speed ratio(M)

2.5螺杆的防护screw protection

1型升降机螺杆的防护分为,基本型,防旋转型(F)和带防护罩型(Z).

2型升降机螺杆的防护分为,基本型和带防护罩型(Z),
