A helical groove is a groove that spirals around a round piece of material over its length or part of its length. They are used in things like gearboxes (gears), helical screw compressors, some types of hydraulic pumps, watches, rack and pinion assembly in cars, etc. Please see the link below for visual examples.

Difference between helical gear and bevel gear?
A bevel gear provides torque and rotation at 90 degrees, and a helical gear provides it at 180 degrees.
Why are helical gears more favourable than spur gears?
bevel gears are used for power transmitting between the shafts which intersect at some angel ( usually right angel) , but the spur gear is used for shafts which are parallel and coplanar.
Which gear type does not have axial thrust?
herring bone gear (Double helical ) doesn't axial thrust
What is Stiffness of a helical spring?
a helical spring has N turns of coil of diameter D, and a second spring made of same material and of same wire diameter has N/2 turns of coil of diameter 2D. if stiffness of first spring is k, then stiffness of second spring is
How much is the cost of a helical gearbox?
Typically £220-£250 It's depend on your model ,such as the power,ratio and so on.
What is major groove in DNA?
The major groove has the N2 & O2 of the base pairs pointing inwards toward the helical axis, while in the minor groove, the N2 & O2 atoms point outwards.

What is helical thickening?
Helical thickening, also known as spiral thickening, is a form of sculpturing. Helical thickenings are part of the S3 layer of the secondary wall.
Is DNA double-stranded and helical?
DNA in its native form is double-stranded and helical.
How many bases are found in one turn of the DNA double helix model?
In molecular biology, the term double helix[1] refers to the structure formed by double-stranded molecules of nucleic acids such as DNA and RNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure. The term entered popular culture with the publication in 1968 of The Double Helix: A Personal Account of the Discovery of the Structure of DNA, by James Watson.The DNA double helix is a spiral polymer of nucleic acids, held together by nucleotides which base pair together.[2] In B-DNA, the most common double helical structure, the double helix is right-handed with about 10-10.5 nucleotides per turn.[3] The double helix structure of DNA contains a major groove and minor groove, the major groove being wider than the minor groove.[2] Given the difference in widths of the major groove and minor groove, many proteins which bind to DNA do so through the wider major groove.[4]
What is the difference between helical spring and coil spring?

What is a helical virus?
A helical virus has a spiraling structure similar to a spiral staircase. The virus genome is arranged in the middle of the spiral staircase. The Tobacco mosaic virus is a helical virus.
