hypoid gear การใช้

• Oils for hypoid gear lubrication will contain high content of EP additives.
• Hypoid gears are still common in larger trucks because they can transmit higher torque.
• The rear axle has a hypoid gear set.
• This hypoid gear is a bevel gear that changes the direction of the drive rotation.
• In older automotive designs, hypoid gears were typically used in rear-drive automobile efficiency.
• A hypoid gear incorporates some sliding and can be considered halfway between a straight-cut gear and a worm gear.
• Special gear oils are required for hypoid gears because the sliding action requires effective lubrication under extreme pressure between the teeth.
• Another advantage of hypoid gear is that the ring gear of the differential and the input pinion gear are both hypoid.
• This allows the table feed to be synchronized to a rotary fixture, enabling the milling of spiral features such as hypoid gears.
• Final drive was by hypoid gears, replacing the worm drive that had been used on final drives in Daimler cars since 1910.
• In rear-wheel drive automobiles the central drive shaft ( or prop shaft ) engages the differential through a hypoid gear ( ring and pinion ).
• API Category GL-4 designates the type of service characteristic of spiral-bevel and hypoid gears in automotive axles operated under moderate speeds and loads.
• Like the DE chassis on which it was based, the DC 27 had hypoid gear drive, independent front suspension, and hydro-mechanical brakes.
• Also note that the designations right hand and left hand are applied similarly to other types of bevel gear, hypoid gears, and oblique tooth face gears.
• Within the torque transfer unit is a short horizontal shaft and a hypoid gear set which turn the propeller shaft ninety degrees and moves it to the vehicle center line.
• The "'back cone "'of a bevel or hypoid gear is an imaginary cone tangent to the outer ends of the teeth, with its elements perpendicular to those of the pitch cone.
• The worm drive is not as efficient as a hypoid gear, and such trucks invariably have a very large differential housing, with a correspondingly large volume of gear oil, to absorb and dissipate the heat created.
• For practical purposes, it is often impossible to replace low efficiency hypoid gears with more efficient spiral bevel gears in automotive use because the spiral bevel gear would need a much larger diameter to transmit the same torque.
• In 1927, Gleason Works again led the innovation in this market, as it was the first machine tool builder to create machine tools to cut hypoid gears ( which are an advanced variant of spiral bevel gears ).
• "' Apex to back "', in a bevel gear or hypoid gear, is the distance in the direction of the axis from the apex of the pitch cone to a locating surface at the back of the blank.
