SUMMARY

The discussion focuses on the design of rack and pinion gears, specifically calculating parameters such as steering ratio, load, and torque. The steering ratio is given as 9.23, with a front load of 1500N and a torque on the pinion calculated to be 9Nm. The torque formula used is T=(2*coefficient of friction*Wf^1.5)/(√(π*p)), with a c factor of 2.19 derived from the equation c factor = 2*module*Zp (pinion teeth). The user seeks assistance in determining the module, teeth selection for the pinion, and other related parameters.

PREREQUISITES
  • Understanding of rack and pinion gear mechanics
  • Familiarity with torque calculations and friction coefficients
  • Knowledge of gear module and teeth selection
  • Basic principles of linear and angular velocity relationships
NEXT STEPS
  • Research how to calculate gear module and select pinion teeth
  • Learn about the relationship between linear force and torque in gear systems
  • Study the effects of friction on gear performance and load calculations
  • Explore the calculation of linear speed of the rack based on pinion angular velocity
USEFUL FOR

Mechanical engineers, automotive designers, and students involved in gear design and analysis will benefit from this discussion, particularly those working under tight deadlines for project submissions.

Hii,
Can anyone help me in designing rack and pinion gears and their formulae...steering ratio of my steering=9.23 ,the load that on front =1500N...I.e.,load to move by pinion ,torque on pinion is 9Nm...that torque was caluclated based on tyre pressure ,friction between tyres,front axle max load,i.e., T=(2*co-efficient of friction*Wf^1.5)/(√(π*p))...was that correct??...c factor =2.19 in . (c factor = 2*module*Zp(pinion teeth)) ...pls help in module finding,teeth selection on pinion,pitch,i heard linear force,speed of pinion ,linear speed of rack...((angular velocity of pinion/linear velocity of rack)=1/radius of pinion) are all required for designing ryt...i don't know how to caluclate linear force those and all...please help ...I m almost in deadline...hope someone will lift me... Tq :)

Thread 'Hydraulic Cylinder Held In Place Until Needed'

I have encountered a vertically oriented hydraulic cylinder that is designed to actuate and slice heavy cabling into sections with a blade. The cylinder is quite small (around 1.5 inches in diameter) and has an equally small stroke. The cylinder is single acting (i.e. it is pressurized from the bottom, and vented to atmosphere with a spring return, roughly 200lbs of force on the spring). The system operates at roughly 2500 psi. Interestingly, the cylinder has a pin that passes through its...
