5. dimensions of the gear: which gear shell be substituted by plastic: gear 1 gear 2 pressure zone at the pitch circle: modulus: material: elastic modulus: surface hardness: roughness height Ra: pitch circle diameter: top circle diameter: ground circle diameter: profile displacement: number of teeth: tooth width: max. permissible flight land clearance HRC µm HRC µm 6. attachment of the gear: please mark with a cross (1) (2) (3) (4) (5) by a positive connection: by pieces dowel pins (1) by a profile shaft (2) by a transverse pin (3) by a flange (4) by a groove wedge 7. surrounding medium: outside use inside use by a non positive connection: by a conical seat by a pressing upon by a shaft nut medium: air with a temperature of and a relative humidity of % chemicals name: concentration: % ph value: temperature: Page 2 of 5
7.1 medium between connecting parts: 8. electrical influences: demanded electrical influences: no lubrication - dry operation - oil lubrication grease lubrication grease lubrication unique water lubrication: available water volume flow rate: existing water flow temperature: maximum water outlet temperature: other: penetration resistance dielectric constant loss factor resistivity surface resistance 9. load on the driving wheel: 9.1. continous load: power: kw screw speed: min -1 permanence of the continous load: how often per time unit does the continous load occur: 9.2. maximum load: power: kw screw speed: min -1 permanence of maximum load: how often per time unit does the max. load occur: kg/s C C kv/ Ohm/cm Ohm type of drive machine: impact factor: type of powered machine: impact factor: ambient temperature: turn on time: % 10. movement: no movement further on at 11. no rotation further on at 10.2 10.1. rotation: continous screw speed: min -1 maximum screw speed: min -1 loading time with continous screw speed: loading time with max. screw speed: permanence of one load cycle: number of load cycles per time unit: how long are the breaks between the load cycles: Page 3 of 5
no oscillation further on at 11 10.2. oscilation: tilting angle: continous frequency: Hz maximum frequency: Hz loading time with continous frequency: loading time with maximum frequency: permanence of one load cycle: how long are the breaks between the load cycles: 11. ambient temperature: permanent temperature: maximum. temperature: how often per time unit does the maximum temperature occur: how long does the maximum temperature occur each time unit: which medium transfers the temperature: which movement and load occurs simultaineously with the heat exposure: radial load: axial load: none none permanent as at 9.1 permanent as at 9.2 maximum as at 9.1 maximum as at 9.2 other: N other: N movement: rotation none permanent as at 10.1 maximum as at 10.1 other: oscillation none permanent as at 10.2 maximum as at 10.2 other: Page 4 of 5
11. working life: wished working life: h permissible clearance increase maximum radial clearance after maximum axial clearance after hours of operation hours of operation 12. miscellaneous: special material wishes additional conditions to be served: The more information you give us by this questionaire, the more precise solution we can work out for your application Please add a representation or a sketck of your application!
