China supplier Zlyj420 Transmission Gearbox for Extruder Single Screws with high quality

Merchandise Description

Item Description

ZLYJ sequence Reduction Gearbox (speed reducer) is a transmission element for most one screw extrusion line, wihch also possesses substantial precision tough gear floor and thrust block made. Created with common ZBJ19009-88, it brings together effectively with most of equipment from distinct suppliers. Also the equipment and axis parts are manufactured of high strength alloy steel with surface area hardness HRC54~sixty two. In the entrance stop of hollow enter axis there is huge specification thrust bearing that will bear axial thrust power even though the screw is functioning

>Applied Circumstance
1. All type of extrusion & blowing machinery
2. Higher pace shaft rotation Speed <1500RPM
three. Working Setting Temp. -forty~45°C, with temperature below 0°C, need to pre-heat lubrication oil to earlier mentioned 0°C

>Major Specialized Index
one. Output Pace: 16-100 RPM
2. Output Torque: Max.4300 Nm
three. Motor Power: 5.5-two hundred Kw

>Selection of Gearbox
1. Pick speed ratio
e.g. input pace n1=1000rpm, output speed n2=70rpm, ratio i=n1/n2=14.28, ought to choose ratio fourteen
two. Select product variety according to input electricity
e.g. enter power P=26kw, after checking type, 29kw>26kw, most ecomonic need to be ZLYJ200
3. Choose assemble type
as per actual use, choose horizontal or vertical type
four. Estimate axial thrust Fa=π*Ds²*Ps/(4*a thousand)
e.g. Screw diameter Ds=75mm, Screw pressure Ps=26MPa
Fa=π*Ds²*Ps/(4*one thousand)=114.8kN
187kN>114.8kN, ZLYJ200 can bear the axial thrust and financial to decide on
5. Affirm link size
six. Verify CZPT type

Parameters Anxious

When hunting at a reducer vs a gearbox, often the only variation is terminology. This is due to the fact all reducers are gearboxes. Nonetheless, not all gearboxes are retarders. This may possibly sound complicated, but it really is in fact very straightforward. A reducer is a gear set between the motor and the equipment. The function of the reducer is to minimize the rotational pace transferred amongst these two endpoints. The reducer amplifies and multiplies the torque (enter) developed by the motor. 2nd, a reducer, as the name suggests, decreases the velocity of the input (output in rpm) so that the output is the right speed. The time period “gearbox” is just a generic time period used for the gear train amongst the motor and the equipment. For that reason, all reducers are gearboxes. Nonetheless, not all gearboxes lessen enter velocity. Although unheard of, gearboxes can truly enhance enter speeds. By far the most common kind of gearbox is a retarder, but it would be incorrect to say that all gearboxes are retarders.
These compact, light-weight, lower backlash inline equipment reducers have been at first designed for encoder apps. They are also appropriate for several other generate methods. Encoder gear reducers have a very lower instant of inertia at the shaft input and are rated for input speeds up to 3000 rpm. Two frame dimensions are available with equipment ratios from 4.96:1 to 3600:1. Our encoder gearbox sync pads are offered from inventory.
