GONGJI TKV Worm Gear Speed Reducer

Cast Iron Worm Gear Reducer. Size 50 till 500, Rated Torque 41 ~ 51,680 Nm, Ratio 10 ~100

In order to meet the needs of various industrial applications, Gong Ji has developed a series of worm gear seducers that matched international standards. With quality raw materials, experienced heat treatment as well as s
Ba
Be of the art CNC  precision grinding of the teeth of worm shaf
Bs, we can ensure smooth and efficient turning as well as long service life. Very quiet and compact. Light weight and elegant appearance. We trust it can contribute a lot to your operations.

(A) Parts details
Housing : Great rigidity for capable of sustaining severe impacts was obtained by one time casting. Good- looking appearance equipped with cooling fins, which combined with quality lubricating oil, allows good heat dissipation. Material FC20 is used for type 80 and under. Material FC23 is used for type 100 and up.
Bearings : Applying high rigidity ball bearings and tapered roller bearings enable fhe unit to sustain both horizontal and  vertical (lateral and  axial) loads to the highest degree.
Worm shaft : The worm shaft is made by one solid piece of carbon alloyed steel. The worm teeth are cut before induction hardening or carbonized to H0C45” or H0Có0” . After heat treatment, the worm teeth are ground by state of
Bhe art precision CNC  grinder to ensure maximum confac

Bh the worm wheel and to increase load-carrying capacity, both in impact and continuous modes.
Worm wheel : Worm wheel are made by special high strength bronze alloy(ALBC2]. The teeth are cut by precision CNC hobbing machines.They are designed to sustain high impact.

(B) How to choose
To choose the righf "GONG Jl"worm gear speed seducers, please check the following parameters:

1. Input shaft rpm : when driven with shaft coupling or belt, the maximum rpm may be up to 2000. However, rpm from ó00-l 800 is recommended.
2. Output shaft rpm : it can be calculated by the rpm of the input shaft and the speed reduction ratio.rpm of outpuf shaft = rpm of input shaft x speed reduction ratio Special attention should be given when very low speed is required due to lower efficiency and torque. It is also more difficult for the gear to be properly lubricated.Please contact the manufacturer to choose the right model as well as the right lubrication oil.
