Description
Technical field
The present invention relates to the transmission device of the high pass power efficiency of the improvement of gearing structure, particularly alternative retarder.
Background technique
[extracts] retarder mainly is made up of driving parts (gear or worm screw), axle, bearing, casing and annex thereof, and its basic structure has three parts: 1. gear, axle and bearing combination: small gear is processed one with axle, claims gear shaft; This structure be used for gear diameter with the axle the relevant little situation of diameter under; If the diameter of axle is d, the Gear Root diameter of a circle is df, then when df-d≤6～7mn; Should adopt this structure; And when df-d＞6～7mn, adopt gear and axle to be split up into the structure of two parts, like lower velocity shaft and gearwheel; This moment, gear connected with the circumferential fixedly flat key of axle, and parts on shaft utilizes the shaft shoulder, axle sleeve and bearing cap to make axial restraint.Diaxon has all adopted deep groove ball bearing, and this combination is used to bear the situation of radial load and little thrust load.When thrust load is big, should adopt the composite structure of angular contact ball bearing, tapered roller bearing or deep groove ball bearing and thrust-bearing.Bearing is the thin oil that splashes when utilizing the gear rotation, is lubricated.The lubricant oil of oil sump in the block, the gear that is rotated splash on the inwall that is splashed to case lid, flow to the flask joint groove along inwall after, flow into bearing through oil guide slot.When immersion oil circumference of gear speed υ≤2m/s, should adopt the grease lubrication bearing, for the thin oil of avoiding splashing washes out lubricating grease, can adopt flinger ring that it is separated.For preventing that become estranged extraneous dust of flow of lubricant from getting in the case, is equipped with seal element between bearing (ball) cover and outrigger shaft.2. casing: casing is the important composition parts of retarder, and it is the pedestal of driving parts, should have enough strength and stiffness.Casing is used the gray cast iron manufacturing usually, for the heavy duty or have the retarder of impulsive load also can adopt the cast steel casing.The retarder that monomer is produced in order to simplify technology, to reduce cost, can adopt the casing of steel plate welding.Gray cast iron has good castability and damping property.For the ease of the installation and removal of shaft components, casing is processed along shaft axis horizonally split formula.Upper box lid and lower box are integral with Bolt Connection.The attachment bolt of bearing support should be as far as possible near bearing saddle bore, and the other boss of bearing support should have enough support faces, so that place attachment bolt, and the spanner space that needs when guaranteeing to screw bolt.For guaranteeing that casing has enough rigidity, adds ribs near bearing hole.For guaranteeing that retarder is placed in the stability on the basis and reduces the machining area on cabinet base plane as far as possible, cabinet base does not generally adopt complete plane.3. retarder annex: in order to guarantee the proper functioning of retarder; Except the structural design to gear, axle, bearing combination and casing gives enough attention, the choose reasonable and the design of auxiliary component such as the accurate location of case lid and block, lifting and parts when also should be taken into account to the oiling of gear reducer lube pond, oil extraction, inspection fuel head, processing and dismounting maintenance.
Retarder can be divided into universal speed reducer and speed reducer dedicated two big classes by purposes; Both designs, manufacturing and handling characteristics have nothing in common with each other; The 70-80 age in 20th century; The retarder technology has had very big development in the world, and combines closely with the development of new technology revolution, and its main type has: gear reducer, worm reducer, gear-worm reducer and plane table thermoconductivity meter.General retarder has helical gear reducer (comprising parallel axes helical gear reducer, worm speed reducer, conic reducer or the like), plane table thermoconductivity meter, cycloidal-pin wheel retarder, worm type of reduction gearing, planetary friction formula mechanical stepless speed changes machine or the like.1. cylinder gear speed reducer single-stage, secondary, the above secondary of secondary, setting type: expansion, flow deviding type, coaxial-type.2. cone gear reducer is used for the occasion that input shaft and output shaft position become to intersect.3. worm reducer is mainly used in the occasion of velocity ratio i＞10, compact structure when velocity ratio is big, and its shortcoming is that efficient is low, at present extensive use Archimedes' worm retarder.4. gear-worm reducer if gear transmission at a high speed level, then compact structure; If worm drive is in the high speed level, then efficient is higher.5. the plane table thermoconductivity meter transmission efficiency is high, and gear range is wide, transmission power 12W ~ 50000KW, and volume and weight is little.
The main feature of retarder is to have reverse auto-lock function, and bigger reduction speed ratio can be arranged, and input shaft and output shaft be not on same axis, and also not at grade, still general volume is bigger, and transmission efficiency is not high, and precision is not high.The harmonic driving of harmonic speed reducer is to utilize the controlled resiliently deformable of flexible member to come transmitting movement and power, and volume is little, precision is very high, but shortcoming is a flexbile gear limited service life, not shock-resistant, and rigidity is compared relatively poor with metalwork, and input speed can not be too high.Its advantage of planetary reducer is that structure is compact, and the backhaul gap is little, precision is higher, and working life is very long, and it is very big that specified output torque can be done, but price is slightly expensive.Retarder: in brief, the power of general machine is after design and creating, and its rated power is not just changing, and at this moment, speed is big more, and then moment of torsion (or torsion) is more little; Speed is more little, and then torsion is big more.
According to existing retarder in sum, can find out, its complex structure, transferring elements is various, and assembling allotment difficulty is heavy and be difficult to move, and maintenance difficulty is big, and transmission efficiency and transmitted power are lower, and power consumption is big.
