Abstract
The invention relates to a wear-resisting gear for a motor, and belongs to the technical field of motors. The wear-resisting gear for the motor is characterized in that a hole is formed in the center of the gear. A method for manufacturing the wear-resisting gear for the motor is characterized in that the wear-resisting gear is made of calcium raw materials, silicon raw materials and carbon fibers, the weight percentage of the carbon fibers and calcium silicate is 0.1-7%, and the calcium silicate is formed by matching the calcium raw materials and the silicon raw materials according to the molar ratio of (0.95-1):1 with CaO and SiO2 as index.
Description
Technical field
The present invention relates to motor wear-resistant gear, belong to technical field of motors.
Background technique
Gear is the colyliform mechanical parts that rely on the engagement transmitting torque of tooth.Gear by with other dentation mechanical parts (as another gear, tooth bar, worm screw) transmission, can realize and change rotating speed and moment of torsion, change the function such as moving direction and change forms of motion.Due to advantages such as transmission efficiency are high, velocity ratio is accurate, power range is large, gear mechanism extensive use in industrial products, its design and manufacture level directly have influence on the quality of industrial products.Gear tooth mutually fastens gear and can drive another gear to rotate to transmit power.By two gears separately, also can apply chain, crawler belt, belt drives the gear on both sides and transmits power.Gear can be by the classification such as surface and manufacture method at profile of tooth, gear shape, tooth trace shape, gear teeth place.Tooth-formation of gear comprises tooth curve, pressure angle, tooth depth and displacement.Table is for gear is by the classification of profile of tooth.
Involute gear ratio is easier to manufacture, and therefore in the modern gear using, involute gear accounts for absolute majority, and cycloidal gear and circular tooth gear application are less.Aspect pressure angle, some country adopted 14.5 ° and 15 ° in the past, but the unified bearing capacity that is defined as 20 ° of little pressure angle gears of majority state is less; And large pressure angle gear, although bearing capacity is higher, increases at the load of the identical situation lower bearing of transmitting torque, therefore large pressure angle gear is only for special circumstances.Tooth depth is standardization, generally all adopts reference addendum.Modified gear advantage is more, has spreaded all in all kinds of machinery.Gear is divided into cylindrical gears, bevel gear, noncircular gear, tooth bar, endless screw-worm gear by its profile.Be divided into spur gear, helical gear, herringbone gear, curved tooth cylindrical gear by tooth trace shape gear.Be divided into external gear, internal gear by the surperficial gear at gear teeth place.External gear teeth tip circle is larger than root circle; And internal gear teeth tip circle is less than root circle.Be divided into cast gear, cutting gear, rolling gear, sintered gear(s) etc. by manufacture method gear.The gear that motor-driven is used is generally enclosed within on the output shaft of motor, because gear easily weares and teares, often needs to change, so not only time-consuming but also effort.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the present invention is to provide a kind of motor wear-resistant gear.
Motor arranges porose with the center of the gear of wear-resistant gear.Gear is made up of carbon fibre material.
Motor wear-resistant gear, is characterized in that: the center of gear arranges porose.
For making the method for motor wear-resistant gear material, it is characterized in that: made by calcareous raw material, siliceous raw material and carbon fiber; The weight percent of wherein said carbon fiber and calcium silicate is 0.1%~7%; Described calcium silicate by calcareous raw material and siliceous raw material with CaO and SiO
2for index is that 0.95~1: 1 cooperation makes in molar ratio.Tooth face hardness HB≤350.
The principle of the invention: gear comprises carbon fibre material, carbon fibre material has selflubricating and wear-resistant.
