Abstract
The invention relates to a loading machine drum-type roller-type overrunning clutch which comprises an outer ring gear, an inner ring cam, an isolating ring, an intermediate input shaft gear, rollers, a spring and a gland. The clutch is characterized in that the rollers are of a waist drum shape; the diameter at the middle of each roller with maximum thickness is phi15-phi19mm; the number of the rollers is 19-48; and the number of the drum types is 0.003-0.05mm. The clutch has the advantages that because the rollers are of the waist drum shape, the contact of the rollers, an outer ring and a cam wheel at the middle part of the rollers can be kept, the unusual damage of the isolating ring caused by the deflection phenomenon when the rollers are combined or separated by the contact at one end is avoided; because the rollers with greater diameter are adopted, which is good for improving the contact strength among the rollers, the cam wheel and the outer ring; and the bearing capability of the overrunning clutch is improved, and the service life of the overrunning clutch is prolonged.
Description
Technical field
The present invention relates to a kind of loader cydariform roller-type overrunning clutch, belong to engineering machinery loader transmission device field.
Background technique
Free wheel device is the easily worn part that generally uses in the present loader, and its structure mainly is made of outer ring gear and the input shaft assembly be made up of interior ring cam, middle input shaft gear, spring, roller etc.The free wheel device of the said structure that generally uses mainly has the following disadvantages at present:
1, since free wheel device at work transmitting torque be that roller is that line contacts with outer shroud by the wedge type space that roller cylindrical and outer shroud endoporus the form wedging work that rubs.Now the free wheel device that generally uses all uses the roller of Φ 13 diameters, because diameter is little, has contact strength deficiency, easy to wear, problem that working life is short.
2, roller is cylindrical, is straight line on axial direction.Because all there are foozle in various degree in cam face that contacts with roller and outer ring gear endoporus, the stressed situation of one end appears in combination back roller easily, cause abnormal working positions such as turning appears in roller, beat, thereby cause the unusual damage of roller and isolating ring.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, keeping that former technical pattern is simple, on the basis of good economy performance, providing a kind of technical more reasonable, stable working is good, the loader cydariform roller-type overrunning clutch of reliable performance, long service life.
The objective of the invention is to realize in the following manner:
The present invention includes outer ring gear, interior ring cam, isolating ring, middle input shaft gear, roller, spring, gland, it is characterized in that: being shaped as of roller is dolioform, its middle part diameter at thick position is Φ 15～Φ 19mm, roller quantity is 19～48, and the cydariform amount of roller is 0.003～0.05mm.
The spread pattern of described roller is single-row or biserial.
Advantage of the present invention is:
1, because roller is dolioform.Can remain roller and contact at the intermediate portion of roller, avoid making roller to occur the undesired damage that the beat phenomenon causes isolating ring when separating in combination by an end in contact with outer shroud and cam.
2,, help improving the contact strength of roller and cam, outer interannular owing to adopt than the major diameter roller.Improve the bearing capacity of free wheel device, prolong the working life of free wheel device.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the broken section enlarged view of A-A portion among Fig. 1;
Fig. 3 is the left view of Fig. 2.
Among the figure: 1: outer ring gear, 2: roller, 3: isolating ring, 4: interior ring cam, 5: middle input shaft gear, 6,7,11: bearing, 8: nut, 9: bolt, 10: gland, 12: spring.
Embodiment
Embodiment: with reference to accompanying drawing, manufacturing and designing a kind of cydariform amount of using is the free wheel device of 0.003 cydariform roller.This free wheel device comprises outer ring gear 1, interior ring cam 4, isolating ring 3, middle input shaft gear 5, roller 2, spring 12, gland 10, and bearing 6,7,11, nut 8, bolt 9; The roller middle part diameter at thick position is φ 15mm, and roller quantity is 24, and roller length is 26mm, and the roller arrangement mode is single-row.Wherein: the cydariform amount is meant minimum diameter poor at the diameter at thick position and roller two ends of roller middle part.
The Main Feature of this free wheel device is:
1. owing to adopt the cydariform roller, overcome because after the foozle of relevant counterparts such as outer ring gear, interior ring cam and middle input shaft gear causes assembling, the outer ring gear raceway, roller and in ring not parallel between cam working face, cause roller end in contact in cohesive process to produce the abnormal working position that beat turns, cause the unusual phenomenon that makes free wheel device early failue of damaging of isolating ring.
2. adopt the roller of 15mm diameter, improved the contact stress between roller and outer ring gear raceway and interior ring cam working face, improved contact strength, prolonged the life-span of free wheel device.
3. length does not change because the roller diameter increases, and makes the roller slenderness ratio reduce (then greatly reducing slenderness ratio when adopting the biserial roller), has improved the straight line of roller in combination and the separation process ability that moves ahead, and has improved the stationarity of free wheel device work.
The model machine that adopts the present invention to make is adopting loader to use under the declared working condition of free wheel device, with the clutch comparative trial of original technology through test stand.
1. when the high speed no load running was tested, model machine of the present invention be can't hear the sound of the friction bump that sends between roller and isolating ring and outer ring gear raceway, and the free wheel device of original technology has noise clearly.
2. under the limit load situation of super Maximum Torque, under the limit load situation of super Maximum Torque, surmount for 3000 times, after the uninterrupted repetition test of combination, disassemble the back contrast, the wear trace of outer ring gear raceway, roller and the interior ring cam working face of invention model machine and original technology contrast free wheel device, be uniform operation friction vestige between the surface of contact of the roller of invention model machine, outer ring gear raceway and interior ring cam working face, do not have to occur the position of obviously heavier abrasion mark.And one of original technology contrast free wheel device is at the outer ring gear raceway oral area one side wide heavier wear trace of 1mm of having an appointment.At roller and interior ring cam working face homonymy obvious abrasion mark point is arranged all.Another has heavier abrasion mark at the two ends that contact with roller and medial side has very light abrasion mark at the outer ring gear raceway.
According to the test comparison result as can be known:
1. the present invention can obviously improve free wheel device in disengaging and cohesive process, roller encircles working state between cam working face in the outer ring gear raceway reaches, the surface of contact of each roller is all kept by the correct working position of centre to the two ends extension, avoided turning the early stage unusual phenomenon of damaging that causes free wheel device owing to beat takes place roller one end in contact.
2. the wear trace of model machine of the present invention is obviously compared according to free wheel device light, illustrate that the present invention improves the roller of free wheel device and the contact stress between outer ring gear raceway and interior ring cam working face, contact strength improves to wear and tear in the corresponding work and reduces, and the life-span is improved.
