[MCQ''s] Machine design 2 - Last Moment Tuitions

The linear velocity of the reciproing roller follower when it has contact with the straight flanks of the tangent cam, is given by. a) ω (r 1 -r 2 )sinθ. b) ω (r 1 -r 2 )cosθ. c) ωr 1 +r 2 )sinθsec 2 θ. d) ω (r 1 +r 2 )cosθcosec 2 θ. Answer: c. Explanation: Velocity = ωr 1 +r 2 )sinθsec 2 θ.

Gears, Velocity Ratios and Mechanical Advantage

What is Velocity Ratio (VR)? •When calculating for velocity or speed, it is best to have a ratio in which the driver gear is larger than the driven gear. –For maximum speed you should always have a larger driver gear/pulley paired with a smaller driven gear/pulley.

Linear Bearing: What Is It? How Does It Work? Uses, Types

Linear bearings are a type of bearing that "bear" or support the load of the carriage during its single-axis linear movement and provide a low friction sliding surface for the guide rails. In a linear guide, the carriage is the component that travels in a straight line, back and forth, along the length of the guide rail.

Bushing or Bearing, what’s the difference?

15/1/2021· Needle Bearings Needle roller bearings may be small, but they’re tough. They get their name from their thin, needle-like appearance, and are used for reducing friction within smaller appliions. The rigid bearings are perfect for appliions with oscillating movement

Flexures - University of Utah

13/9/2021· Linear motors can be easier to make clean room compatible as the wear of linear bearings is the only source of contamination. The wear points of ballscrews, belts, rack and pinion or other mechanisms with mechanical power transmission are generally less desirable for clean room operation due to the nuer of particles ejected during operation.
