Chain saw matched with toothless chain wheel of stone cutting machine

Abstract

The invention provides a chain saw matched with a toothless chain wheel of a stone cutting machine. The chain saw matched with the toothless chain wheel of the stone cutting machine comprises inner chain pieces, outer chain pieces and tool bits; each front outer chain piece and the corresponding rear outer chain piece clamp the corresponding left inner chain piece and the corresponding right inner chain piece, left mounting holes of each front outer chain piece and the corresponding rear outer chain piece are connected with a right mounting hole of the corresponding inner chain piece through a shaft sleeve and a pin shaft, and right mounting holes of each front outer chain piece and the corresponding rear outer chain piece are connected with a left mounting hole of the other corresponding inner chain piece through a shaft sleeve and a pin shaft; tool bit mounting holes are formed in the upper ends of the outer chain pieces, and the tool bit mounting holes of each front outer chain piece and the corresponding rear outer chain piece are connected with the corresponding tool bit through a corresponding small pin shaft in a tight fitting mode; a semicircular opening is formed in the center position between the left mounting hole and the right mounting hole of each inner chain piece, and a semicircular opening is formed in the center position between the left mounting hole and the right mounting hole of each outer chain piece; and the lower portions of the semicircular openings are slanting openings. When the chain saw matched with the toothless chain wheel of the stone cutting machine is matched with the toothless chain wheel, the semicircular openings in the chain saw are tightly attached to rollers of the toothless chain wheel in a rolling friction mode; and the chain saw has the characteristics of low noise, small vibration, low temperature and long service life.

Description

technical field [0001] The invention relates to a chain saw matched with a toothless sprocket on a stone cutting machine. Background technique [0002] The inventor has previously applied for three utility models, namely: "Stone Cutting Chain Saw", ZL2013200385908; "Stone Tooth Cutting Chain Saw", ZL2013208092816; "An Improved Chain Slice on Stone Cutting Chain Saw" , ZL2015206492071; what they have in common is that the tooth shape meshes between the chain saw and the sprocket, which belongs to sliding friction. When the sprocket runs at high speed, the tension force makes the mesh between the chain saw and the sprocket slide and rub, which will generate high temperature, high noise, high vibration, and short service life. Since oil cannot be lubricated when cutting stone, the sliding friction between the chain saw and the sprocket will cause rapid wear and affect the quality of stone cutting, especially when cutting large granite slabs.

Problems solved by technology

When the sprocket runs at high speed, the tension force makes the mesh between the chain saw and the sprocket slide and rub, resulting in high temperature, high noise, high vibration, and short service life

Since oil cannot be lubricated when cutting stone, the sliding friction between the chain saw and the sprocket will cause rapid wear and affect the quality of stone cutting, especially when cutting large granite slabs.
