What is Rack and Pinion? A rack and pinion (wheel gear) is a type of A circular gear called “Pinion”, and the engaged teeth on a linear linear actuator that comprises a pair of gears gear bar called “Rack”. Rotational motion applied to the pinion which convert rotational motion into linear causes the rack to move, thereby, translating the rotational motion (reciprocating motion). motion of the pinion into the linear motion of the rack. Advantage of Rack and Pinion High Dynamic Performance High Stabilization Low Mass Moment of Inertia Low Cumulative Error Unlimited Travel Distance Higher...

Vertex Precision Installation of Jointed Racks Put racks on base (end to end) without screw on; Put opposite tooth gauge on both ends of jointed racks. For keeping smooth and precise motion, Tooth on both ends of jointed racks will be made by half for combining a complete tooth. The opposite tooth gauge is used for adjusting the pitch position. Opposite tooth Gauge Screw on both racks on base in sequence, and then pin the bore hole in the final. Opposite tooth Gauge Rack A

Vertex Precision Terminology Addendum: The distance between the top land of the gear tooth and the pitch circle. Addendum Circle: Circular Pitch An imaginary circle that passes through the addendums of the gear teeth. Face width The distance between the bottom land of the gear tooth and the pitch circle. Dedendum Circle: An imaginary circle that passes Tooth thickness through the dedendums of the gear teeth. Base Circle: Pitch Circle Base Circle In an involute curve, the circle from which the curve is unwound in a spiral shape. Circular Pitch: The distance from a point on one gear tooth to...

Vertex Precision Module Calculation Module is the unit of size to indicate how big or small a gear pinion is. It is the ratio of the reference diameter of the gear pinion divided by the number of teeth. Thus the formula of module calculation of gear pinion is: Reference Diameter Number of Tooth The relation between the module and the reference diameter is as following: Reference Diameter (Rd) = Module (M) x Number of Teeth (Nt) Number of Teeth (Nt) = Reference Diameter (Rd) Module (M) Reference Pitch (Rp) = π x Module (M) For example The table presents the method for calculating the mesh of...

Vertex Precision Calculation of Mechanical Transmitting Usually we’re used to describe the power of the electronic device with a load capacity possessed; but for servo motor system, the main part is the output torque which could guide the relative concepts. From the notion of the motor driving circuit design, the power is focused especially. For the purpose we must clarify the relationship among the power, the torque, and the speed: ( Pw ) = Force (F) x Linear Velocity (V) Torque ( TNm ) Force (F)= Radius (r) Through above formulas we can get F = Torque (Tnm) / Radius (r) Linear Velocity...
