The power tables apply to normal conditions, i.e., drive by an electric motor, smooth operation, operation for eight hours per day,s 2.5-fold starting torque relative to catalogue performance PN, 100% duration of operation, ambient temperature 200 C. Power for intermediate speeds can be interpolated linearly.Higher drive speeds than indicated and selection as finite-fatigue strength gears on request.Reinforced bearings are optional for heavy external forcses (e. g. output drive by pinion). |
• 99 % for single reduction helical gear boxes
• 98 % for double reduction helical gear boxes
• 97.5% for triple reduction helical gear boxes
• 97% for quadruple reduction helical gear boxes
The figures are not strictly binding. We reserve the right to modify dimensions. The indicated weight and oil quantities are average values. When filling gear unit with oil, note oil level markings.
The housing can be made of nodular cast iron or of fabricated steel. Additional heating cartridges can be built into the housings. Special seals may be provided when the plant has to be set up in dusty or humid surrounding.
Before the gear unit is set up the operating instructions should be studied and followed. Inclined positions for installation are Possible on request. The plant user should provide protection covers on rotating parts.
Allowable noise level is generally as mentioned below
(a) Gearbox with C.I. housing: 85 d B
(b) Gearbox with fabricated housing: 90 d B
(c) Gearbox with fan or built in pump will have 5 d B higher than (a) & (b)
