The utility model can be widely used for the various mechanical variable-speed gears of various lines at home and abroad.
Description
The utility model is a kind of novel mechanical formula stepless speed variator that is used for transmission system, belongs to transmission device.Can be widely used in the various mechanical speed change structures in industries such as light industry, weaving, food, packing, plastics, printing, household electrical appliances, electronics and the various production line.
At present, ripe mechanical transmission general in the Domestic market has level, and type of belt drive is based on gear, cycloidal-pin wheel, fewer differential teeth planetary etc.Step change transmission far can not adapt to modern transmission and with the requirement of external product synchronized development.As: the changeable or continuous variation of process parameter, cutting different-diameter bar; Seek optimum speed, several coordination operations; Situations such as slow starting all need the speed of continuously changing and adopt stepless speed variator.And adopt that stepless change can be boosted productivity, quality of product, rationally utilize power, realize remote control etc.The domestic product close with the present invention is mechanical type planetary cone wheel stepless speed variator (XZW type), but this product category few (only 8 kinds), slewing range narrow (0~833rpm) and mechanical output characteristic only have the output of perpetual motion rate, its accommodation is narrower.Also different fully on boundary dimension with the utility model.
The purpose of this utility model provides a kind of new mechanical formula stepless speed variator, is to possess speed changer wide ranges, wide in variety and possess the advanced product that good output characteristic is arranged, to satisfy the higher requirement widely of the modern transmission system in home and abroad.
The purpose of this utility model realizes in the following way:
This product is made of four major parts, and (1) includes the driving mechanism of input shaft, output shaft, input rotating disk, output supporting disk, tapper, tapper retainer.(2) contain the speed regulating mechanism of handwheel, worm and gear, location tooth bar, speed ring.(3) contain the pressurization device of butterfly spring, automatic Regulation dish, gasket ring.(4) contain supportings such as casing, case lid, bearing, be connected and fixed member.Wherein, driving mechanism adopts and keeps tapper three-point support structure to realize tapper rotation, the synthetic output movement of revolution.Tapper adopts the geometrical shape that adapts with three-point support to guarantee to realize reasonable transmission simultaneously.For tapper (3000~4000 rev/mins) under high speed is rotated, adopt the lube oil additive of high performance index, when both satisfying high speed rotating 1. non-slip 2. be subjected to cooling off 3. when bearing certain frictional force, reduce parts depreciation and 4. realize not changing continuously in the lubricant oil using process as far as possible.For the high speed rotating that guarantees tapper is established the bimetal axle bush that heat resistant and wear resistant decreases in the tapper retainer.Be to guarantee speed ring self-locking behind a certain output speed, promptly guarantee the speed change transmission steadily, ripple disable and stable output speed, be provided with the appropriate facility that makes the speed ring self-locking in the speed regulating mechanism.Adopt butterfly spring in the pressurization device, to guarantee to decide moment of torsion output.Be provided with steel ball in the automatic Regulation dish, be protected when making the complete machine overload by its action.
Further specify with accompanying drawing below.
Fig. 1 three-point support structure driving mechanism schematic representation
The omnipotent shape stepless speed variator of Fig. 2 structural drawing
Fig. 3 Fig. 2 side Visual figure
See Fig. 1, locate all uniform one group of tappers [ 3 ], be positioned in the tapper retainer [ 8 ], bimetal axle bush [ 9 ] is set between the two along input garden dish [ 2 ].Make last 2 a of tapper [ 3 ] by butterfly spring [ 13 ], automatic Regulation dish pressurization devices such as [ 7 ]
1a
2Contact with output supporting disk [ 5 ] respective point with input garden dish [ 2 ] respectively and compress.On the outer garden face [ 3a ] of tapper [ 3 ], at point of contact a
3The place with not rotating movably speed ring [ 4 ] contact and compress.Speed ring in the speed regulation process [ 4 ] moves axially (seeing that heavy line is to fine line among the figure) and promptly carries out stepless speed regulation on the garden face [ 3a ] outside tapper [ 3 ].
See that Fig. 1, Fig. 2 motor [ 10 ] directly are connected with input shaft [ 1 ].When the power by motor [ 10 ] drives input shaft [ 1 ], input garden dish [ 2 ] rotation, by point of contact a
1Frictional force drive tapper [ 3 ] and do following two kinds of rotations: keep the revolution parallel and the rotation of tapper [ 3 ] itself with input shaft [ 1 ] axial direction.Revolution speed is determined by the speed that permanent power motor [ 10 ] drives input shaft [ 1 ] rotation, is constant N
1The speed of rotation is variable Nx, is determined by following two factors: 1. speed regulating mechanism is to speed ring [ 4 ] effect, through point of contact a
3Size to the frictional force of tapper [ 3 ] applied pressure and generation.2. by point of contact a
3Along with tapper [ 3 ] outer surface [ 3a ] of input shaft [ 1 ] parallel axes on the mobile position.The synthetic back of these two kinds rotations of tapper [ 3 ] becomes the rolling form, and the rotating speed after changing is passed through point of contact a
2Frictional force pass to output supporting disk [ 5 ], pass to output shaft [ 6 ] through automatic Regulation dish [ 7 ] cam again, obtain output speed N
2Be variable.
Techno-economic effect of the present utility model is as follows:
1. speed changer is wide in variety, owing to adopted the drive mechanism of three-point support, axial force is little, makes this new work transmission when permanent power input, and power has 16 kinds of specifications in 0.2KW~7.5KW. 2. slewing range is wide, when importing revolution at 1500rpm(50HZ) time, output revolutions can reach 165~1000rpm; When input speed at 1800rpm(60HZ) time, its output speed is 200~1200rpm. 3. output characteristics is improved: only output speed is at 610rpm(60HZ) more than be constant power output, and at 530rpm(50HZ) below realized permanent torque output. 4. adopt Self-pressurizing agri, work can Lean on, the life-span was more than 15 years. Lubricating oil need not be changed in 20,000 hours. 5. effect is sensitive, the transmission efficiency height, and 6. compact conformation, volume are little, in light weight can to reach 88~95%, and capacity is big, the bearing capacity height. 7. artificial speed governing can be adopted, automatic speed regulation can be adopted again. 8. the economic and social benefits of this novel product are as follows: in 10,000 of annual production and sales. Domestic: 1000 yuan/platform of price, 1,000 ten thousand yuan of annual value of production, wherein cost is 6,000,000 yuan, 1,500,000 yuan of tax revenues, 2,500,000 yuan of profits, energy-conservation 2,500 ten thousand degree. Abroad: 500 dollars/platform of price. Earn foreign exchange 5,000,000 dollars every year. This product is owing to have advanced reasonably structure and superior performance, not only be based on the domestic market, accelerate the replacement of various step change transmissions, and adapt to the design of international up-to-date trend and moderate price has been opened up the international market with it, the prospect of earning foreign exchange is very considerable.
