Description

A kind of high-power machinery retarder

Technical field

The utility model relates to retarder, is specifically related to a kind of high-power machinery retarder.

Background technique

Adopting the roll squeezer new technology is cement in China industry development trend; Wideling popularize application; But the speed reducer as the crucial corollary equipment of roll squeezer does not also carry out the exploitation and the design of system at present; Particularly high-power roll squeezer speed reducer, because output power is big, traditional multi-stage gear engagement slowing-down structure is difficult to reach requirement.

The model utility content

The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of function admirable is provided, reliable quality high-power machinery retarder.

For realizing above-mentioned purpose; The technological scheme of the utility model is a kind of high-power machinery retarder of design, and said retarder comprises casing, input shaft and main shaft, on said input shaft, is provided with first gear; On said main shaft, be provided with second gear, said first gear and second gear engagement; It is characterized in that; Said main shaft is connected with the one-level sun gear through crowned teeth, on said casing, is fixed with the one-level ring gear, said one-level sun gear and the coaxial setting of one-level ring gear; Between said one-level sun gear and one-level ring gear, be engaged with the one-level planetary gear set; Said one-level planetary gear set is uniformly distributed on the circumference between one-level sun gear and the one-level ring gear by primary planet carrier, said primary planet carrier and the coaxial setting of main shaft, transmitting torque; Said first gear, second gear, crowned teeth, one-level sun gear, one-level ring gear and one-level planet wheel are helical gear or are spiral gear, and said input shaft and main shaft are supported on the said casing through double-row roller bearing.

Wherein, Said primary planet carrier is connected with the secondary sun gear through crowned teeth; On said casing, also be provided with the secondary ring gear; Said secondary sun gear and the coaxial setting of secondary ring gear are engaged with the secondary planet wheels between said secondary sun gear and secondary ring gear, said secondary planet wheels are uniformly distributed on the circumference between secondary sun gear and the secondary ring gear by the secondary planet frame; Said secondary planet frame and the coaxial setting of main shaft are supported on the said casing as output shaft and through double-row roller bearing.

Said one-level planetary gear set or secondary planet wheels are made up of 3 to 6 planet wheels.

The advantage and the beneficial effect of the utility model are; Because this retarder has the planet wheel with sun gear, ring gear engagement; Export torque to planet carrier through planet wheel; And the multi-stage speed-reducing transfer of torque can be set as required, meet high-power machinery deceleration requirement, bearing capacity is big, transmission capacity is big, transmission is accurate, volume is little, in light weight, installation and maintenance are easy, long service life.
