Description

The invention relates to the timber industry of the wood processing industry and can be used for sawing timber trees. A well-known sawing frame, soda1, without stalling, saw frame, connecting rod, crankshaft, whose bearings are mounted on hangers, allowing the crankshaft to oscillate in horizontal | parallel to the direction of giving the log direction, thereby reducing the bed oscillations in this direction l3. The disadvantage of this frame is the inability to dampen tilts in other directions. Also known is a sawing frame containing a frame, a saw frame with directional lines, an extra-large viS mounted on a support platform in the upper part of the frame, and a sch 23, However, using a frame for cross-linking a circle (horizontal oscillations in the horizontal plane are impossible as platinum springs can work on bending in a strictly defined (across) direction. The lack of a full frame is also a high Hai box spring springs, which perform the functions of elastic CBsiaeA, providing a frequency adjustment vibrations of vibration-damping masses, and supports that raise the weight of vibration vibration - ish mass. As a result, fastening, connection of plate springs with constant vibration vibration masses are quickly weakened and destroyed, which greatly reduces the reliability of the forest (axle frame). The increase in reliability due to a decrease in the loading of the elastic connections of the vibration damping masses. The goal is achieved by the fact that the vibration mass of the mass is mounted on the supporting platform by means of NECAL supports. FIG. Figure 1 shows the sawmill, the general view; in fig. 2 — node 1 in FIG. 1 {in FIG. 3 - node II in FIG. 2; in fig. 4 is a section A-A in FIG. 2; in fig. 5 is a section BB in FIG. four; in FIG. 6 - section on phto. 5 {fig. 7 - section GG on g. 5. On the foundation 1 mounted hundred. Nina 2 and crankshaft 3. The crankshaft is connected with a 4c drinking frame 5. The saw frame is mounted with the possibility of a vertical extension from a drive (not shown) in the Haii equalizing bed 2. The upper bed of the bed is fixed / a supporting platform a @ , inside which the ria of the ball bearings 7 is installed with a voorimost gorneon tal'rg per eshevd vfogaschaya weight 8 with H9 Right 1 1 1 grooves 9, in which in} (spi with the possibility of vertical displacement of the trunnion 10 adjustment mechanism 11. The trunnion 10 with the help of the nut 12 has screw 13, which-, ry in the upper part of b The 14 is rotatably mounted in Nagi equal to 5 eaves of the vibration-suppressing mass 8 and is locked by a washer 16. The Uai fas 10 of the regulating mechanism is connected to the lower end of the elastic link rod 17 of the IS. The threads of the upper end of the rod 17 are screwed on nuts 19, pressed and with axial displacement & upper washer 20 and spring 21 to lower washer 22, which with its axis 23 is installed with the possibility of turning in tensioning lugs 24 of tensioning device 25. Tensioning device 25 with guide grooves 26, tightening screws 27 and locking screws 28 secured with POSSIBILITY movement on the support platform 6. The frame saw runs sleduk uiHM manner. I The initial compression of the spring 21 of the elastic links 18 is provided with a tensioning device 25. For this, the OTW locks the screws 28 and rotate the tension screw 27 and the tensioning device moves along the guide slots 26 of the support 1 Shatforin 1 6. The axis 23 of the lower washer 22 moves (us 24 tension device 25 in the direction from vibration-suppressing mass 8. Lower washer 22 presses spring 21 to upper washers 20. When moving, tension device 25 in view and end of weight 8 of elastic links 18 weakened After installation the preset oh, and the initial press-up stops are tightened in. 28 The dead weight 8 adjusts its natural oscillations with a frequency corresponding to the working revolutions of the shaft 3. The coarse tuning is done by selecting the spring 21 of the elastic connections 18. The spring constant selection 21 is independent

tuning of the frequency of own copeba-research institute of vibration damping mass in in both horizontal directions. Thin Hadw rokuka provide (chivaepgs by means of adjusting mechanisms 11. To do this, with the washer 16 unscrewed, the screw 13 will stir the trunnion in the slots 9 of the vibration damping mass 8 in the vertical direction. The trunnion 10 rotates the elastic link 18 in the eyes 24 nat. 25. The angle of inclination of the elastic coupling axis to the mountain axis of the gnal plane is changed, which leads to a change in the magnitude of the projection of the elastic force of the spring 21 on the horizontal plane and provides for the frequency control of the vibration damping mass 8. The vertical component of the projection of the forces of prulsin 21 is less than the weight of the vibration-suppressing mass 8, therefore it does not detach it from the ball bearings 7. When the angle of inclination of the elastic link 18 to the horizontal plane increases, the frequency of vibration oscillations of the vibration-suppressing mass decreases. In the long run, the tsiuyu setting of the natural frequency at first begins for yitpyiTHX links operating in the longitudinal direction of the head lice.

locking against the guide lugs 15 with locking washer 16.

 The inertial loads that excite progressively moving the crankshaft and crankshaft joints of the crankshaft-and-shafts and affect the foundation 1 and stfoshu 2. As a result, the bed with the foundation oscillates intensively in a horizontal plane in the longitudinal and transverse directions. The oscillations of the Stage 2, I act through the tension devices of the device 25 and the ultrasound links 18, excite the vibrations of the vibration-suppressing mass 8 in the near-horizontal plane. In this case, the vibration damping mass 8 is transferred to the ball bearings 7 relative to the supporting platform 6.1. As a result, the forces generating oscillations of a hundred to two in the longitudinal and axial directions of the front axle are absorbed by the forces of the elastic damping mass of 8, which reduces the longitudinal and transverse horizontal cop: bathhouse bed.

Installation of vibration damping mass 8 on. The ball joints 7 provide the front load with a vertical load from the weight of the vibration damping mass 8 of the supporting platform 6, which is elastic. 18. 1
