RU14880U1 - BAND SAW MACHINE - Google Patents

Abstract

1. A band saw machine drive, comprising a base on which an intermediate shaft is mounted, connected, for example by a V-belt drive, to a drive pulley of a saw apparatus, and a chain saw, in which the tire and chain are removed, and the drive sprocket is replaced by a pulley, which, in turn, connected by a V-belt drive with an intermediate shaft, characterized in that the chainsaw with its flange for attaching the tire is attached to a lever mounted on an axis that is stationary relative to the base, and this axis is located so that the rotation in the lever region together with the chainsaw allows you to adjust the degree of slippage of the chainsaw pulley during acceleration of the drive pulley of the saw apparatus. 2. The gasoline drive according to claim 1, characterized in that the intermediate shaft is driven into rotation by two chainsaws at the same time.

Bandsaw machine gasoline drive The utility model relates to bandsaw machines and is designed to drive a horizontal sawmill. Known band saws with electric drive. For the operation of such machines, a three-phase power supply network is necessary, which is not always possible l. Machine tools with a gasoline drive are also known, for example, the company Husqvarna s, in which a gasoline engine from a chainsaw is used as a drive. Domestic industry does not produce ICE with the same parameters. Domestic chainsaw power is not enough, on the one hand, when pulleys and a saw band are accelerated, having a large inertia (the centrifugal clutch of the chainsaw is lit), on the other hand, when sawing logs of large diameter. The purpose of the proposed technical solution is the use of domestic chainsaws to drive a band saw. 15/02

The intermediate shaft, connected, for example, by a V-belt drive, with a drive pulley of the saw apparatus, and a chain chainsaw, in which the tire and chain are removed and the drive sprocket is replaced by a pulley, which, in turn, is connected by a V-belt drive with an intermediate shaft, the following elements have been introduced: The chainsaw is fastened to the tire by its fastener for fastening the tire to a lever mounted on an axis fixed relative to the base, and this axis is located so that the rotation of the lever around it together with the chainsaw allows you to adjust the degree of skalzyvaniya pulley chainsaw during acceleration of the driving pulley of the saw unit. To increase the power of the gasoline drive, the intermediate shaft can be driven into rotation by two chainsaws at the same time.

In Fig. I shows a rear view of a fragment of a band saw with a gasoline drive; figure 2 is the same in the process of accelerating the saw tape; Fig. 3 is a view A in Fig. 1; figure 4 is a top view of the drive with one chainsaw.

The gasoline drive consists of a base I, on which an intermediate shaft 2 is mounted with pulleys 3 and 4. The pulley 3 of the shaft 2 is connected by a V-belt to the shaft 5 of the drive pulley 6 of the saw apparatus. A saw band 7 is dressed on the driving pulley 6 (see Fig. 1,2,3). On the base I, a lever 8 is installed, which has a hook 9 for fixing the chainsaw 10. The chainsaw is attached to the hook 9 with its flange for mounting the tire . The lever 8 is installed on the axis II, which is located between the axis of the intermediate shaft 2 and the axis of the pulley 12 of the chainsaw 10. The pulleys 12 and 4 are connected by a V-belt. (, see also figure 4) .0 axis II is stationary relative to the base I. Thus, the lever 8 can rotate around axis II together with the chainsaw 10 and the pulley 12. When the chainsaw 10 is rotated counterclockwise (figure 2}, the distance between the pulleys 12 and 4

decreases, which ensures slippage of the pulley 12 during acceleration of the driving pulley 6 of the saw apparatus and facilitates the working conditions of the chainsaw. To connect two chainsaws to the drive at the same time, the shaft 2 is equipped with two pulleys 4, and on the basis of I jopa of the lever 8 is installed (Fig. 3.4).

The petrol drive works as follows. The chainsaw 10 is attached to the lever 8. In the position shown in FIG. 1, the chainsaw is started with a starter and put into the position shown in FIG. 2. Increase the engine speed of the chainsaw to maximum and smoothly translate it into position in figure 1. When the saw blade 7 accelerates to cut south.

If the power of one chainsaw is not enough, then on a free 8 (see Fig. 43 set the second chainsaw (see Fig. Z). Chainsaws in turn start and saw two at the same time.
