Technical Field

[0001] The invention belongs to the technical field of oil saw chains and relates to an oil hole modification structure of a transmission sheet of an oil saw chain assembly. Background Art

[0002] In the prior art, the oil guide hole on the transmission plate is in the shape of a circular hole. In each section of the saw chain assembly composed of a blade, a transmission plate and a chain plate, the circular hole-shaped oil guide hole cannot contact the chain plates and blades on both sides of the transmission plate during the operation of the saw chain, thereby causing greater wear of the saw chain during operation.

[0003] For example, a Chinese patent discloses a saw chain connecting plate, a saw chain and a saw chain transmission system [application number: 202020541678.1], including a connecting plate body, on which two rivet holes are provided, and the diameter of the rivet holes gradually expands from the inside to the outside to form a trumpet-shaped outer expansion opening. The diameter of the rivet holes on the connecting plate body is a trumpet-shaped outer expansion opening that gradually expands toward the outside. After the rivet inserted into the trumpet-shaped outer expansion opening is rolled, the outer surfaces of both ends of the rivet are extended and fit on the trumpet-shaped outer expansion opening, and the outer end surface of the rivet is basically flush with the outer surface of the connecting plate body or embedded in the trumpet-shaped outer expansion opening. Summary of the invention

[0004] The object of the present invention is to solve the above-mentioned problems and to provide a transmission plate oil hole modification structure of a chain saw chain assembly.

[0006] The invention discloses an oil hole structure for a transmission plate of an oil saw chain assembly, comprising symmetrical blades arranged alternately on the left and right, chain plates for connection, transmission plates for transmission, and chain shafts for articulating the blades, chain plates and transmission plates. The transmission plates are provided with an oil guide hole structure, and both ends of the oil guide hole structure extend toward the blades and chain plates and can be connected to the blades and chain plates respectively.

[0007] In the transmission plate oil hole structure of the above-mentioned chain saw chain assembly, the oil guide hole structure includes an oil guide hole. When the blade, chain plate and transmission plate are in the same straight line, the two ends of the oil guide hole are respectively connected to the blade and the chain plate.

[0008] In the above-mentioned transmission plate oil hole modification structure of the oil saw chain assembly, the cross-sections of the two ends of the oil guide hole are semicircular.

[0009] In the transmission plate-to-oil hole structure of the above-mentioned chain saw chain assembly, the oil guide hole penetrates the transmission plate front to back so that the left and right staggered blades can all be connected to the oil guide hole.

[0010] In the transmission plate oil hole modification structure of the above-mentioned chainsaw chain assembly, the transmission plate is in a triangular structure, wherein a transmission bayonet is formed at one corner, and the transmission bayonet has straight edges on both sides and an outwardly protruding arc portion between the two straight edges.

[0011] In the above-mentioned transmission plate oil hole modification structure of the chain saw chain assembly, a plurality of heat dissipation holes are arranged at the lower side of the transmission plate.

[0012] In the above-mentioned transmission plate oil hole modification structure of the chain saw chain assembly, a side of the chain plate away from the cutting edge of the blade is inwardly recessed and provided with a No. 1 notch portion.

[0013] In the above-mentioned transmission plate oil hole modification structure of the chain saw chain assembly, a second notch portion is provided inwardly recessed on the side of the blade away from the cutting edge.

[0014] In the above-mentioned transmission plate oil hole modification structure of the oil saw chain assembly, an inner oil guide groove structure is also provided in the blade.

[0015] In the above-mentioned transmission plate oil hole structure of the oil saw chain assembly, the inner oil guide groove structure includes an oil guide groove arranged on the side of the blade close to the No. 2 notch portion, and the middle part of the oil guide groove close to the No. 2 notch portion has a raised section, and the height of the raised section is higher than the height of the two sides of the oil guide groove, and the two ends of the oil guide groove respectively penetrate the blade toward the chain plate and the transmission plate.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. In a chain saw assembly consisting of a blade, a chain plate, a transmission plate and a chain shaft, the oil guide hole structure on the transmission plate, which extends from both ends toward the blade and the chain plate and can be connected to the blade and the chain plate respectively, can make the area through which the lubricant can flow larger, thereby increasing the coverage of the lubricant in the chain saw assembly after adding the lubricant, thereby achieving the purpose of reducing wear.

[0018] 2. The oil guide hole is in the shape of a long strip, and both ends of the oil guide hole can be connected to the blade and the chain respectively, which can improve the diffusion effect of the lubricant, make the coverage area of ​​the lubricant larger, and thus reduce the wear of the chain saw assembly during operation.

[0019] 3. The oil guide groove can connect the two sides of the blade. When the chain saw is operating, the lubricating oil on the oil-rich side of the blade can be transferred to the oil-poor side through the oil guide groove, which can make the lubricating oil on both sides of the blade more evenly distributed.
