Problems solved by technology

[0007] More specifically, good dosing of tank pumped oil is difficult with existing lubrication methods and systems, since the volume pumped increases with the speed of the motor and would result in the delivery of large amounts of useless oil; In addition, this speed is reduced when greater cutting force is required, thus reducing the amount of oil delivered to the chain at times when better lubrication is required to reduce heat and wear

Embodiment Construction

[0033] An advantageous but non-limitative example of the method of operation of the chainsaw and the lubrication system according to the invention is described below with reference to the accompanying drawings.

[0034] A chainsaw with a bar is described below, but it should be noted that the invention is also applicable to chainsaws with various handles (with simple handle, with raised handle, etc.).

[0035] figure 1 Shown is a chainsaw 1 with a bar comprising a control handle 2 mounted at the lower end of a tubular bar 3 with a cutting head 4 rotatably mounted at its upper end.

[0036] The cutting head 4 comprises an endless cutting chain 5 mounted on the outer circumference of a drive pinion 9 and a chain guide 6 . The drive of the cutting chain 5 via the transmission pinion 9 is realized by an electric motor, which at figure 1 contained in the housing 7 and in the image 3 Indicated by reference numeral 8 . It is also not excluded that the drive is realized by means...

Abstract

The chainsaw has an endless cutting chain (5) rotatably mounted on a driving pinion (9) and a chain guide (6) that is provided with a guiding rail. A driving motor (8) drives the cutting chain by the pinion. A driving pump (13) e.g. peristaltic pump, drives lubrication liquid i.e. oil, towards the chain and the chain guide from a lubrication liquid storage reservoir (11). The pump is connected toan electric driving motor (13A) that is independent from the motor (8) of the chain (5). An independent claim is also included for a method of lubricating a cutting device of a chainsaw.

Description

technical field [0001] The invention relates to a chain saw provided with a lubrication device for a chain guide / cutting chain assembly. The invention also relates to a method for performing this lubrication. Background technique [0002] Chain saws, commonly referred to as cutters, are well known and are commonly used for cutting various materials (wood, concrete, brick, ashlar, etc.). It comprises a cutting device consisting of an endless cutting chain mounted for rotation around a drive pinion and a chain guide generally formed in the shape of an oblong and provided with a circumferential guide rail, and a power source, such as Consisting of a thermal motor or an electric motor) is used to drive the chain through said pinion. [0003] For such tools to function well, it is necessary to ensure effective lubrication between the chain guide and the cutting chain to reduce friction, which generates heat, reduces efficiency, accelerates wear and consumes energy. [0004] To...
