Description
Technical field
The invention belongs to mechanical engineering technical field, be specifically related to a kind of swinging land leveller equipment based on short tooth profile of tooth.
Background technology
Land leveller is a kind of earth moving plant of utilization shovel (scraping) cutter ground grading; Perching knife (body) and for guaranteeing that perching knife (body) accomplishes the assembly of other devices of diversity job task and be commonly referred to the land leveller equipment be that the equipment of operative body has six-freedom degree and moves with perching knife (body).The land leveller equipment is made up of rocker, hitch frame, revolution (mechanism) device and perching knife (body) assembly etc.Rocker is installed on the pendulum rail of front frame, can rotate around the pendulum rail, and be connected with hitch frame with hydraulic jack, realizes moving up and down and swinging (the hitch frame front end is a ball pivot) of perching knife (body).The hitch frame Front-end Design is ball pivot (allowing to rotate); Be passed to perching knife to tractive force from forebay through hitch frame simultaneously; The hitch frame rear end is lifted bottom at hitch frame to gyration gear ring (when adopting pivoting support as slewing equipment through guide plate; Use bolt), and allow gyration gear ring (or pivoting support) to do gyration.Revolution (mechanism) device is made up of hydraulic motor, worm reduction box, gyration gear ring (or pivoting support) etc.Wherein, Hydraulic motor is connected with worm shaft, forms one with worm reduction box again, is installed on the hitch frame; Worm and gear slow down to realize slows down to increase and turns round that (purpose that adopts worm and gear to slow down is both to have realized big speed reducing ratio; Make the reduction box height unlikely too high again), worm gear is equipped with coaxial pinion, pinion and gyration gear ring engagement (slow down to increase once more and turn round); Drive gyration gear ring (or pivoting support) motion, gyration gear ring (or pivoting support) drives perching knife (body) again and does gyration and (can realize 360 in theory
0Revolution).Perching knife (body) assembly is made up of support, position, angle device and perching knife etc.Support is welded on the gyration gear ring (or be connected in pivoting support on bolt), and position, angle device is fixed on position, the angle device installation shaft of support, utilizes hydraulic jack to adjust the perching knife angle; Perching knife also is connected with the horizontal hydraulic pressure oil cylinder, can slide along slide block and slide rail lining, realizes the move left and right of perching knife through stretching of oil cylinder.(, all calling perching knife to perching knife (body) or perching knife (body) assembly) for convenient following statement.
To push away the soil of (scraping) more and when carrying out the revolution of perching knife simultaneously when perching knife, and turning round on the gyration gear ring (commentaries on classics) square just requires bigger.Install the torsional analysis on the gyration gear ring of realizing from turning round (mechanism): the output torque on the hydraulic motor axle; Slow down (can be called the first order slows down) through worm and gear, obtain turning round on the gyration gear ring (commentaries on classics) square by (pinion is coaxial with worm gear) pinion and gyration gear ring engagement (deceleration) (can be called the second level slows down) again.When worm and gear speed reducing ratio (first order deceleration) timing, the speed reducing ratio that increases pinion and gyration gear ring (second level deceleration) as much as possible is just most important to the output torque on the gyration gear ring.
The method one that increases the speed reducing ratio of pinion and gyration gear ring (second level deceleration) is the size (diameter) that increases gyration gear ring, the 2nd, and the number of teeth of minimizing pinion.The size of gyration gear ring (diameter) increases and to receive structural restriction, and the strength of gear teeth of gyration gear ring will satisfy bending, contact fatigue strength requires and anti abrasive requirement etc.; Reduce the number of teeth of pinion, adopt the involute standard tooth form, can receive the restriction of undercut (number of teeth is less than 17), (X-gear is compared with master gear, the equal no change of its modulus, the number of teeth, reference circle and basic circle even adopt gear modification; But the thick increase of calibration knuckle-tooth during normal shift, the corresponding increase of root circle with the tooth top fenestra; Negative addendum modification is then opposite with normal shift) etc. measure, and allow gear to produce a certain amount of undercut, guarantee that pinion is continuous with the gyration gear ring engagement, under the condition of easy motion, the number of teeth of pinion also is difficult to reduce to a less value.In addition, the profile of tooth of gyration gear ring and pinion is exactly to adopt a kind of nonstandard profile of tooth, and the number of teeth of pinion can reduce to a less value (the common pinion number of teeth is 6 teeth).
At present, the monolithic gyration gear ring adopts steel plate cutting mostly, and what profile of tooth adopted is non-target profile of tooth, is processed by shape cutting (or gear shaping) etc.When the gear of gyration gear ring can not make it reach certain intensity through heat treatment, the gear of gyration gear ring was when load is big, and with regard to easily deformable, wearing and tearing, the gear root such as is easy to crack at the fatigue failure phenomenon.Gyration gear ring adopts solid forging (because physical dimension is big, high to forging equipment and technical requirements), after the gear parts of gyration gear ring carries out certain heat treatment, can significantly improve its intensity and anti abrasive performance.But the profile of tooth of gyration gear ring and pinion is still the number of teeth that adopts shape cutting (or gear shaping) to reduce pinion when realizing bigger gearratio; The profile of tooth quality of its processing normally is difficult for (and processing cost is not low yet) of assurance; Owing to be a kind of nonstandard profile of tooth, pinion and gyration gear ring engagement requirement continuous, easy motion also is difficult to guarantee (in fact, because the speed of gyration of gyration gear ring is relatively slow; Even have certain discontinuously, also be difficult for manifesting).
Adopt the gyration gear ring of pivoting support formula, gear can adopt the involute standard tooth form, but the number of teeth of pinion is difficult to reduce to a less value, and the moment of torsion of increase will move forward on the worm and gear, is easy to occur the fatigue damage of worm and gear.
Is the problem of the swinging land leveller equipment existence of core in order to solve above-mentioned with revolution (mechanism) device, proposes a kind of revolution (mechanism) device based on short tooth profile of tooth, and the quality and the performance of swinging land leveller equipment are greatly improved.

0Deng, also can the displacement correction or produce certain undercut) swinging land leveller work (mechanism) device of the nonstandard profile of tooth of profile of tooth or shape cutting is identical.Can also further extend to: the deceleration forms that have many input lists of above (motor, worm reduction box and the integrated apparatus that pinion constituted coaxial with the worm gear) integrated apparatus of two covers and two covers and a gyration gear ring (or pivoting support) engagement (interior engagement and external toothing also all can) to export, develop into swinging land leveller equipment more malformations, with better function.
Among the present invention about the principle of short tooth profile of tooth with the pinion minimizing number of teeth:
The very few serious problems that cause of the pinion number of teeth are exactly Undercutting Phenomenon.Undercut causes that Gear Root is thick to be reduced, and has reduced tooth root intensity.Short tooth profile of tooth can be improved the undercut problem to a certain extent.Under same modulus, short tooth tooth depth is lower than the tooth depth of standard involute profile, and short tooth whole depth is less than the whole depth of standard tooth form, and the dedendum line length of the length overgauge profile of tooth of short tooth dedendum line is so short tooth profile of tooth has increased tooth root intensity.The addendum thickness of short tooth profile of tooth is much larger than the addendum thickness of standard tooth form, so adopt short tooth profile of tooth can increase addendum thickness.Use the gear-driven registration of the short tooth profile of tooth corresponding reduction of meeting.The speed of gyration of considering land leveller revolution (mechanism) device is lower; Guaranteeing that registration (can make registration bigger greater than 1 as far as possible; Guarantee the continuity and the stationarity of gears engaged) condition under; Use displacement correction (generally adopting the normal shift correction) again, allow again under certain under cut technical measures such as (preferably not producing undercut) and can realize that the number of teeth of pinion is minimum.The displacement correction has influence on the undercut degree to a great extent, increases tooth root intensity thereby normal shift can reduce undercut, and negative addendum modification is then opposite.For the design of this gear, adopt normal shift in principle.For increasing tooth root intensity, should under the situation of conditions permit, increase modification coefficient as far as possible.Adopt normal shift that addendum thickness and registration are also had certain influence.Normal shift helps increasing tooth root intensity, but has reduced addendum thickness, has reduced the gears engaged registration, can confirm the scope of modification coefficient according to the relation of modification coefficient and registration.Both guarantee the requirement of strength of pinion and gyration gear ring, and can realize bigger gearratio again.In addition, from processing analysis, the short tooth profile of tooth of the short tooth system of standard can adopt standard involute serrated knife to process, and cost is processed nonstandard gear and reduced, and quality can be better.The deceleration form of the mesh form of pinion and gyration gear ring (or pivoting support) (interior engagement and external toothing) and many inputs, single output has also further expanded the form of land leveller swinging equipment.Therefore adopt short tooth profile of tooth can make the number of teeth descend (reach the number of teeth and be 6 even still less the number of teeth); Registration and intensity can meet the demands; Just in time reach land leveller revolution (mechanism) device about the few requirement of the pinion number of teeth, so a kind of swinging land leveller equipment that proposes based on short tooth profile of tooth.
Beneficial effect of the present invention:
1, lacks tooth profile of tooth and gear modification correction thereof, the certain technical methods such as undercut (registration is not less than 1 in principle) of permission; The number of teeth that has realized the worm reduction box coaxial pinion of revolution (mechanism) device in the land leveller equipment is few, and revolution (mechanism) has more suitably gearratio.Make land leveller revolution (mechanism) device, prolong simple in structure, application life, greatly improves swinging land leveller equipment reliability thus, also makes the corresponding very big raising of reliability of land leveller complete machine.
2, the deceleration form of mesh form of pinion and gyration gear ring (or pivoting support) (interior engagement and external toothing) and the single output of many inputs has also further expanded the form of land leveller swinging equipment; Can solve the problem of more powerful swinging land leveller equipment thus, for the extension of land leveller product line is laid a good foundation.
3, because short tooth profile of tooth can use the standard involute gear cutter to process, compare the profile of tooth of copying, reduced equipment requirements, reduced cost, also make whole work (mechanism) apparatus structure compact.
