Abstract
The utility model discloses a power transmission apparatus which is used for matching with a rotary tilling machine when a walking tractor (comprising a ploughing and leveling machine) uses a transversal power shaft to output a side power. The utility model is transmitted by an independent two stage bevel gear and a one stage intermediate shaft. The both ends of the transmission shaft tube are welded with the upper contact of a transmission shaft and the lower contact of a transmission shaft by the intermediate shaft. The outside of the intermediate shaft is provided with the welding element of a support frame tube which is connected with the transmission shell body of the existing bevel gear, so as to form a fully sealed transmission of the intermediate shaft. A structure capable of transmitting power in a unidirectional mode and interlocking with the back action is designed. Compared with the transmission mode of a cylindrical gear, the utility model has long service life of parts, reliable operation, good sealability, small structural quality, no limitation of transmission distance, good back action and interlocking and high safety performance without frequent adjustment.
Description
The utility model is applicable to that a kind of actuating unit that supporting rotovator adopts was passed to rotovator with tractor dynamic power when hand tractor (comprising harvesting and tillage machine) adopted the lateral dynamics axle to do the output of side power.
The existing biography ploughed the machine transmission device and had two kinds: first kind be adopt one-level or two-stage chain drive (as with the transmission device of workers and peasants-12 type and TY-61 type walking tractor matching), its defective is the elongation of link wear rear chain, cause easily and take off chain, so need often to adjust chain stretching device.Chain withstands shocks after the load, and the life-span is short, and functional reliability is poor.Second kind is to adopt column gear transmission, and when its shortcoming was the transmission distance, required gear, axle and number of bearings were many, casing is big, cost is high, and the transmission distance heals defective far away more obviously.
The purpose of this utility model is to avoid the problems referred to above, and a kind of frequent adjustment that do not need is provided, life-span length, reliable operation, the not limited novel rotovator transmission device of transmission distance.
For reaching above-mentioned purpose, the utility model adopts independently Bevel Gear Drive and the transmission of one-level jackshaft of two-stage.Jackshaft can adopt in welding power transmission shaft top connection of transmission shaft tube two ends and power transmission shaft lower contact and constitute.Be connected with two-stage Bevel Gear Drive casing respectively at jackshaft outer setting support tube soldering member, the joint face place adds the adjustment pad, to form hermetic jackshaft transmission.Adopt matched in clearance between power transmission shaft top connection and one-level driven gear, be connected with adopting spline between claw collar.Adopt between one-level driven gear and claw collar can only unidirectional delivery power pairing tooth embedding syndeton.
Adopt above-mentioned rotovator transmission device not need frequent adjustment, the driving parts life-span is long, work by good, the good airproof performance of property, good operation safety, architecture quality is little, the transmission distance is not limited, transmission distance more tool superiority far away, this external cause has the unidirectional delivery power function makes it that very high safety in utilization be arranged.
Further specify below in conjunction with accompanying drawing.
Fig. 1 is a kind of rotovator transmission structures figure
The one-level Bevel Gear Drive is constructed as follows: one-level driving gear 32 is connected with gear box of tractor power take-off 33 by spline.One-level driven gear 9 can only unidirectional delivery power with the pairing end face tooth embedding of claw collar 6.All the other parts are: bearing cap 1, paper washer 2 and 29, one-level transmission case body 3, rolling bearing 4,10, clutch spring 5, pair gear shift fork pivoted arm 7, clutch yoke 8, oil sealing 11, loam cake 12, bearing block 31.The secondary Bevel Gear Drive is constructed as follows: secondary is loaded on the rotary ploughing cutter shaft 21 by dynamic bevel gear 23, and this axle 21 is parallel with gearbox power take-off 33.All the other members are: secondary drive bevel gear 24, rolling bearing 16.20,22, paper washer 17,18, bearing block 19, oil sealing 11, secondary transmission case body 25, adjustment pad 26.The transmission of one-level jackshaft is constructed as follows: jackshaft adopts transmission shaft tube 28 two ends welding power transmission shaft top connection 13, power transmission shaft lower contact 15 to constitute, constitute the support tube soldering members with lower cover 27 and be connected with I and II transmission case body 3,25 with alignment pin 30 with bolt at central siphon 28 peripheral hardware support tubes 14 and the loam cake 12 that is welded on its two ends.Its joint face place adds adjustment pad 26, has realized hermetically sealed jackshaft transmission, and has improved integral rigidity.The direction of transmission shaft tube 28 is vertical with axle 21 with axle 33.9 of power transmission shaft top connection 13 and one-level driven gears adopt matched in clearance, and 6 of claw collars are in transmission connection with spline, and claw collar can be moved axially in the power transmission shaft top connection.Whole device is connected as a single entity with hand tractor gearbox body and draw-gear respectively with bolt by one-level transmission case body 3 and Connection Block (not shown).
The course of work: during tractor work, power imports this device one-level driving gear 32 into by output shaft of gear-box 33, pass to rotary ploughing cutter shaft 21 through gear 9, tooth embedding 6, top connection 13, transmission shaft tube 28, lower contact 15, secondary bevel gear 24,23 in turn, its transmission direction is vertically become laterally by horizontal change again.When the tractor extension reversed gear, the rotary blade of rotovator did not allow to rotate, and promptly needs to cut off rotovator power.At this moment, the driver is as long as the pulling height closes handle, drive a pair gear shift fork pivoted arm 7 by the pull bar (not shown), clutch yoke 8 is rotated, driving claw collar 6 moves vertically, the embedding of end face tooth is thrown off mutually, and this moment, one-level was dallied in power transmission shaft top connection 13 by dynamic bevel gear 9, realized cutting off the purpose of power.If drive the person's of going into maloperation, promptly under the situation of not cutting off rotovator power, directly hang to reverse gear and move back car, because the embedding of end face tooth has unidirectional force-transfer characteristic, this moment, rotary ploughing cutter shaft 21 still can not rotate, and the interlocking purpose thereby realization rotovator and tractor reverse gear has improved processing safety.
