Problems solved by technology

Another solution is disclosed in US 4,319,502 which consists of a grinding wheel rotating in a vertical plane, however this solution does not compensate for the convexity of the surface to be sharpened
In addition, the device is too large and heavy for field work, and is disadvantageous in terms of power consumption

Embodiment Construction

[0018] The device according to the invention comprises a body 1, starting from its first side (in the given case from the upper side) two arms 2, 3 formed on each longitudinal end of said body, a gap 4 being arranged in said between the arms. The body 1 is formed with a groove 5 from its second side (in a given case from the bottom) such that the body 1 resembles the shape of an inverted letter U in the transverse direction. Said groove 5 runs through the body 1 in the region between the two arms 2, 3 so that it is connected to the gap 4 and serves to accommodate the saw blade 6 of the pulling chain 7 consisting of the teeth 8 and the Said teeth are constituted by links of an integral guide member 9 , each said link being connected to the chain 7 by means of a pair of pins 10 .

[0019] A spatially curved bracket 12 is secured to the free end, ie the upper end of the aforementioned arm, by fastening means 11 so that the bracket can be selectively moved along an arc and the fa...

Abstract

A device for sharpening chain saw teeth, in particular of a chain saw which is portable and applicable in the field, and where the chain is not to be taken off the chain saw blade when sharpened enables swinging of a grinding wheel (16) transversaly to each tooth (8) of a chain (7) resulting in plane cutting faces of each tooth (8). The grinding wheel (16) of the relatively small diameter is rotated by an actuator (15) of the suitably small power and high number of the revolutions resulting in high cutting speed. Said actuator (15) can be either electric motor, supplied with electricity from electric mains or a battery, a pneumatic motor or a hydraulic motor.

Description

technical field [0001] The present invention relates to a device for sharpening the teeth of a chain saw, in particular a chain saw that is hand-held and suitable for use in the field, and in which the chain is not removed when the chain saw blade is sharpened. Background technique [0002] There are several known solutions for sharpening chainsaw teeth, all of which are either limited to use in maintenance and repair equipment or to different embodiments of hand files. Thus, for example, in US 3,172,306 a solution is disclosed which enables the file to be guided in a set direction, providing a precise geometry for the cutting surface of each tooth. The disadvantage of this solution is that sharpening is slow and reproducible sharpening is not ensured even for closely spaced teeth. The device is unstable in use and not suitable for use in any position. Another solution is known from US Patent No. 4,762,027, in which the grinding wheel moves during sharpening over a dome de...
