Description

(54) ПРИВОД ЛЕСОПИЛЬНОЙ РАМЫ(54) DRIVE FOREST FRAME

Изобретение относитс к лесопильной промышленности и может быть использовано при распиловке бревен.The invention relates to the sawmill industry and can be used when sawing logs.

Известен привод лесопильной рамы, содержащий двигатель, расположенные симметрично относительно рабочего органа и соедин ющие двигатель с имеющими противовесы водилами механические передачи, сателлиты и установленные на ос х сателлитов кривошипы, KOTOE ie соединены с рабочим органом при помощи эксцентриковых пальцев и расположены с внутренних сторон ведомых элементов механических передач Г1 .The drive of the sawing frame is known, which contains an engine located symmetrically with respect to the working member and connecting mechanical drives with mechanical gears to the engine, satellites and cranks mounted on the axles of the satellites, KOTOE ie connected to the working member with eccentric pins and located on the inner sides of the driven elements mechanical transmission G1.

Известен также привод лесопильной рамы, содержащий двигатель, расположенные симметрично .относительно рабочего органа и соедин ющие двигатель с имеющими противовесы водилами механические передачи, ведомые звень которых имеют противовесы, сателлит и соединенные собой валом выходные звень в виде кривошипов, расположенных с внутренних сторон ведокых элементов механических передач 21.Also known is a drive of a sawing frame containing an engine, located symmetrically with respect to the working member and connecting mechanical drives to the engine with counterweights, whose driven members have counterweights, a satellite and shaft-connected output links in the form of cranks located on the inner sides of the mechanical elements gears 21.

Недостаток этих приводов - громоздкость и сложность конструкции.The disadvantage of these drives - the bulkiness and complexity of the design.

Цель изобретени - уменьшение габаритов и повышение надежности привода .. The purpose of the invention is to reduce the size and increase the reliability of the drive ..

Это достигаетс тем, что водила жестко смонтированы на внутренних сторонах ведомых элементов механических , например ременных передач, кривошипы расположены с внешних сторон этих элементов, а сателлит смон10 тирован на св зывающем кривошипы валу , причем противовесы водил жестко св заны между собой.This is achieved by the fact that the carrier is rigidly mounted on the inner sides of the driven elements of mechanical, for example, belt drives, the cranks are located on the outer sides of these elements, and the satellite is mounted on the connecting crank shaft, and the counterweights of the carrier are rigidly connected to each other.

25 виде кривошипов 7 и 8, противовесы 913 , двигатель, выполненный, например, в виде одного или двух электродвигателей 14. Двигатель соединен с водилами 3 и 4 с помощью механических, например ременных, передач 15 и 16 с25 as cranks 7 and 8, counterweights 913, an engine made, for example, in the form of one or two electric motors 14. The engine is connected to the carriers 3 and 4 by means of mechanical, for example, belt, gears 15 and 16 s

Claims

30 driven and driving elements in the form of pulleys 17, 18 and 19, 20, while the carrier 3 and 4, respectively, are rigidly mounted on the inner sides, and the counterweights 11 and 12 are installed in the outer cavities of the pulleys 17 and 18. The cranks 7 and 8 sec. The weights 9 and 10 are interconnected by a shaft 21 on which the satellite 5 is mounted, and by links 22 and 23 mounted on their hinges 24 and 25 are rigidly connected to the working body 2. The counterweights 13 are driven 3 and 4 are rigidly interconnected. When the engine is executed in the form of a single electric motor 14, the pulleys 19 and 20 are interconnected by a common shaft 26 installed in the pivot bearings 27 and 28. The drive works as follows. When the engine 14 is turned on, the gears 15 and 16 are driven to rotate elements, e.g. pulleys 17 and 18, which, by tight coupling with carrier 3 and 4, cause the latter to rotate. When the carrier rotates 3 and 4, the satellite 5 rolls around gear 6, while cranks 7 and 8 and connections 22 and 23 connected to the latter, as well as working body 2, perform a predetermined reciprocating motion or movement along an elliptical trajectory. When the drive is in operation, the counterweights 9 and 10 balance the reduced mass of the working member relative to the axis of the satellite 5, and the counterweights 11–13 completely balance the entire drive system - the operating member. The use of this design with water allows it to increase its reliability, reduce its dimensions, additionally increase the rigidity of the drive - working system and reduce the level of vibrations that occur during sawmill operation, thereby improving the quality of sawing. In addition, the movement of the working body along an elliptical path allows for more rational cutting conditions, increasing the wear resistance of the saws. Claims 1. The drive saw blade, cor holding the engine, are located symmetrically with respect to the working member and connects the engine to the mechanical gears having counterweights, the driven members of which have counterweights, satellite and crankshaft interconnected shaft, characterized in that in order to reduce overall dimensions and increase reliability, the carrier was rigidly mounted on the inner sides of the driven elements of mechanical gears, the cranks are located on the outer sides of these elec cops, and the satellite is mounted on the shaft connecting the cranks, and the counterweights are rigidly connected to each other. 2. The drive according to claim 1, characterized in that the mechanical transmission is made of a belt. Sources of information taken into account when the experts (giza 1.
