GRINDING FEEDS AND SPEEDS

Dec 15, 2016The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

The CNC Generating and Profile Grinding Machines LCS

The most efficient grinding method for gears is CBN generating grinding. The continu - ous contact of grinding worm and gear eliminates non-productive idle times. CBN allows cutting speeds of more than 70 m/s. They are achieved with a small tool di-ameter of 140 mm and high spindle speeds up to 12,000 rpm resulting in very short cycle times.

How much gear grinding does it take to destroy a

Grinding is when you are slamming these two pieces together, the synchro and the collar gear. Shifting without the clutch will grind because the engine is keeping the gear the same speed and just cause lots of friction. From reading your post, I feel like maybe you are keeping the shifter loose enough that it is just rubbing against the synchro

Troubleshooting: Gears are hard to shift

Oct 02, 2012Sometimes, you may also need to change the gear cable (in a cable shift mechanism) if the cable has become hard with age. Gears make grinding sound on quick shifts. If the gears do not slot easily and instead make a grinding sound on quick shifting between one gear and another, you may have a larger problem on your hands.

Manual transmission

The resulting speed difference between mainshaft and reverse idler gear produces gear noise [grinding]. The reverse gear noise reduction system employs a cam plate which was added to the reverse shift holder. When shifting into reverse, the 5th/reverse shift piece, connected to the shift lever, rotates the cam plate.

Bevel gear

Bevel gears that have pitch angles of exactly 90 degrees have teeth that point outward parallel with the axis and resemble the points on a crown. That's why this type of bevel gear is called a crown gear. Mitre gears are mating bevel gears with equal numbers of teeth and with axes at right angles.

Diagnosing Manual Transmission Problems

If the transmission is running quiet, but is difficult to get into gear without grinding, the synchronizers are bad. They are the same circumference as the gears, but are narrow and in place of teeth they employ triangular-shaped short teeth designed to slow the main gear, making it easier to mesh the gear bank.
