Quality Gear Manufacturer in Ukraine
Manufacturing of transmission parts with external gearing:
Manufacturing of gears, gear wheels, spiral bevel gears and spur gears, double helical wheels, worm gears, sprockets. With an outer diameter of 20 mm to 800 mm and the weight up to 2,000 kg, Metrical module of teeth is from 0.5 mm to 20 mm. And also we can cut into the teeth with pitch module, if a customer gives us their tools.
Manufacturing of gear-shafts, pinion shafts, spline shafts, worm shafts, double helical shafts. Shafts with an outer diameter up to 600 mm, the length is 4 m max and the weight is 4,000 kg max. Metrical module of teeth is from 0.5 mm to 20 mm. The teeth quantity is from 6 to 200 pcs.
Manufacturing of gear racks. Gear racks with the length is 3 m max and metrical module of teeth is from 1 mm to 12 mm.
Manufacturing of transmission parts with internal gearing:
Production of couplings and gears with internal teeth. The maximal workpiece height up to 200 mm, outer diameter up to 800 mm, and any metrical module of teeth is from 1 mm to 12 mm.
Keyways and internal splines manufacturing We produce broaching splines on workpieces with the outer diameter is 500 mm max and the height is 200 mm max.
Repair of gears, gear wheels, gear shafts. We perform the replacement ring gear or bushings and cut teeth.
The production cost is calculated after receiving the customer's drawings or photos with a description of the parts, including all the sizes and main parameters. In case of calculating the cost from a customer's photos, the samples must be sent to production place for further manufacturing.
Gear, gear wheel
Determination of gear
The gear or gear wheel - is the most important part, which is used in a meshing system and performs the main function - transfers rotational motion between the shafts, by means of engagement with the teeth of adjacent gears. Gear looks like a disc with conical or cylindrical surface on which are arranged equidistant teeth. In a meshing system, the bigger wheel in diameter is called a gear and the smaller is called a pinion. If the mechanism uses a pair of gears with equal numbers of teeth, called the leading pinion, and driven - gear. But most of all gears small and large called the gear.
Types of gears, pinions, gear wheels
The gears are mainly distinguished by the type of teeth. The gears can be straight, slanted or spiral teeth. And also them to divide the cylindrical and conical gears.
Spur gears or straight-cut gears
Spur gears are the simplest type of gear. They have a cylindrical disk with straight or skew teeth projecting radially. The teeth have an angle profile, usually it is 20, 30 degrees. The gears are located on parallel shafts for the transmission of rotational motion with a certain coefficient (gear ratio). Gears are fixed to the shaft using dowels or splines.
Gears manufacturing methods
For the manufacture of gears used such materials: iron, cast iron, bronze, carbon steel Easy, special steel compositions with an admixture of chromium, nickel, vanadium. In addition to the metals used softening materials: leather, fiber, paper, they mitigate the gearing. But metal gears can operate silently, if the profile is made with precision. For rough gear unit gear wheels are made of cast iron and steel, without further processing. Gears for high-speed transfers are made on milling machines and gear cutting, followed by heat treatment - cementation or nitration, which gives teeth hardness and wear resistance.
