>Introduction
ZLYJ collection Reduction Gearbox (speed reducer) is a transmission element for most solitary screw extrusion line, wihch also possesses high precision hard equipment surface and thrust block made. Designed with regular ZBJ19009-88, it combines effectively with most of equipment from various suppliers. Also the equipment and axis elements are produced of substantial toughness alloy metal with floor hardness HRC54~62. In the front conclude of hollow input axis there is huge specification thrust bearing that will bear axial thrust force while the screw is functioning
>Applied Circumstance
one. All sort of extrusion & blowing machinery
2. Higher speed shaft rotation Speed <1500RPM
3. Operating Surroundings Temp. -40~45°C, with temperature underneath 0°C, must pre-heat lubrication oil to over 0°C
>Major Complex Index
1. Output Pace: sixteen-one hundred RPM
2. Output Torque: Max.4300 Nm
three. Motor Electrical power: 5.5-200 Kw
>Selection of Gearbox
one. Choose pace ratio
e.g. input velocity n1=1000rpm, output velocity n2=70rpm, ratio i=n1/n2=14.28, must choose ratio fourteen
two. Decide on design sort in accordance to enter power
e.g. input electricity P=26kw, after examining kind, 29kw>26kw, most ecomonic must be ZLYJ200
three. Decide on assemble sort
as for each genuine use, pick horizontal or vertical kind
4. Estimate axial thrust Fa=π*Ds²*Ps/(4*1000)
e.g. Screw diameter Ds=75mm, Screw strain Ps=26MPa
Fa=π*Ds²*Ps/(4*1000)=114.8kN
187kN>114.8kN, ZLYJ200 can bear the axial thrust and economic to decide on
five. Verify relationship dimensions
6. Verify CZPT sort

EXTRUSION SCREW BARREL INJECTION SCREW BARREL TWIN SCREW BARREL
Planetary gearboxes are used in a variety of situations where high efficiency and substantial reduction ratio are required in a tiny space. Featuring high precision and large torque-to-volume ratio, it is perfect for torque increase, deceleration, specific positioning and management of regenerative equipment. To make sure that the picked planetary gearbox is the very best suit for your software, it is crucial to consider parameters these kinds of as torque, backlash and gear ratios when deciding on a planetary gearbox.
These compact, light-weight, minimal backlash inline equipment reducers have been originally designed for encoder apps. They are also suitable for several other travel programs. Encoder gear reducers have a quite low second of inertia at the shaft enter and are rated for enter speeds up to 3000 rpm. Two body dimensions are offered with gear ratios from 4.96:1 to 3600:1. Our encoder gearbox sync pads are available from stock.
