Miter gear
| Diamond Glossary (алмазы и бриллианты - глоссарий терминологии) |
Bevel gear 1 mit sampler a single-tube, drive-type, soil-sampling barrel especially adapted to sampling deposits of plastic clay where a minimum 5-inch-diameter sam¬ple is required a loop or snare of piano wire is inserted in a groove inside the cutting shoe with the free end of the wire extending through a slot on the side of the sampler to the surface when pulled, the wire cuts the sample off at the bottom of the cutting shoe

Gear, английский
- Engrenage
- A machine part which transmits motion and force by means of successively engaging projections, called teeth. the smaller gear of a pair is called the pinion; the larger, the gear. when the pinion is on the driving shaft, the gear set acts as a speed reducer; when the gear drives, the set acts as a speed multiplier. the basic gear type is the spur gear, or straight-tooth gear, with teethe cut parallel to the gear axis. spur gears transmit power in applications utilizing parallel shafts. in this type of gear, the teeth mesh along their full length, creating a sudden shift in load from one tooth to the next, with consequent noise and vibration. this problem is overcome by the helical gear, which has teeth cut at an angle to the center of rotation, so that the load is transferred progressively along the length of the tooth from one edge of the gear to the other. when the shafts are not parallel, the most common gear type used is the bevel gear, with teeth cut on a sloping gear face, rather than parallel to the shaft. the spiral bevel gear has teeth cut at an angle to the plane of rotation, which, like the helical gear, reduces vibration and noise. a hypoid gear resembles a spiral bevel gear, except that the pinion is offset so that its axis does not intersect the gear axis; it is widely used in automobiles between the engine driveshaft and the rear axle. offset of the axes of hypoid gears introduces additional sliding between the teeth, which, when combined with high loads, requires a high-quality ep oil. a worm gear consists of a spirally grooved screw moving against a tooth wheel; in this type of gear, where the load is transmitted across sliding, rather than rolling surfaces, compounded oils or ep oils are usually necessary to maintain effective lubrication.
- Редуктор; коробка передач
- A general term for ropes, blocks, tackle and other equipment
- A catchall nautical term covering [1] any assembly of sails, lines, tackles, etc. [2] the personal effects of a crew member. [3] a toothed wheel that meshes with another to provide a mechanical advantage, to increase force or speed, or to reverse direction.
- A synonym for feed gear.
- The accessory tools and equipment required to op erate a drill.
- A set of enmeshing-toothed rotating parts or cog wheels designed to transmit motion.
- Generic term for the tools of fishing – rod and reel, hook and line, etc.

Scale arbritary quantitative units by means of which the scratch hardness of a mineral is de¬termined the units of hardness are expressed in numbers ranging from 1 through 10, each of which is represented by a mineral that can be made to scratch any other mineral having a lower-ranking number; hence the minerals are ranked from the softest, as follows: talc (1) ranging upward in hardness through gypsum (2), calcite (3), fluorite (4), apatite (5), orthoclase (6), quartz (7), topaz (8), corundum (9) to the hardest, diamond, with the highest ranking number (10) compare knoop hardness
