According to the saw blade group circular saw machine provided by the utility model, a motor in a machine body drives a transmission system in the transmission case through the power input end of the transmission case which is connected with the machine body, thus an inner output shaft and an outer output shaft which are arranged at the power output end of the transmission case are driven to concentrically and oppositely rotate, and a saw blade group, which is clamped on the flanges of the inner and outer output shafts and comprises a pair of circular saw blades suitable for opposite rotation, is driven to work; and the power output end and the power input end of the transmission case are both arranged on the main transmission case.
Description
Technical field
The utility model relates to a kind of saw blades groups circular sawing machine and transmission case body thereof, is applicable to the cutting hard object, for example is used to cut wood or metal, and circular sawing machine is a power driven cutter, relates in particular to the saw blades groups circular sawing machine of a kind of pair of saw blade.First saw blade in the saw blades groups suits on first direction, to rotate around a rotation, and second saw blade suits on the second direction opposite with first direction, to rotate around same rotation, and two saw blades are suitable approaching parallel to each other when rotated.The transmission case body that also relates to a kind of saw blades groups circular sawing machine in addition.
Background technology
Can know following technical scheme from Chinese patent ZL200420082318.0 etc.: the saw blades groups circular sawing machine; Its transmission case body is formed by connecting transmission main box and the assembling of transmission-case cover two parts usually; The power intake of transmission case body is arranged on the transmission main box; The clutch end of transmission case body is arranged on the transmission-case cover; Concentric and the anti-phase rotation of the inside and outside output shaft of clutch end drives the saw blades groups that contains a pair of suitable saw blade that rotates in opposite directions that is clamped on the inside and outside output shaft flange and carries out work.The power intake of transmission case body and the clutch end of transmission case body are the branch body structures.
The shortcoming of the saw blades groups circular sawing machine of transmission case body split organization plan is: the power intake of transmission case body and the clutch end of transmission case body belong to different component respectively; The assembling and positioning precision of the transmission system in the transmission case body receives the influence of transmission main box and transmission-case cover two member machining accuracies; Can accumulate two member mismachining tolerances; Strengthen axial and radial error; Make the transmission system of carrying out produce impact, vibration and noise, reduce the life-span of transmission system, even can cause circular sawing machine normally to move.The guard shield that is used to protect saw blade simultaneously is assemblied in the outer arm of the clutch end of transmission case body usually, and the guard shield reliability of fixation also receives the influence of transmission main box and transmission-case cover bonding strength.
Summary of the invention
The purpose of the utility model is: saw blades groups circular sawing machine and transmission case body thereof that a kind of easily manufactured, low-cost long-life simple in structure is provided.
The utility model is realized through following technical scheme:
A kind of saw blades groups circular sawing machine; Motor in the body drives the transmission system in the transmission case body through the power intake with the joining transmission case body of body; The inside and outside output shaft that drive is arranged on the clutch end of transmission case body rotates with one heart and in opposite directions; The a pair of suitable saw blades groups of the saw blade of rotation in opposite directions that contains that drive is clamped on the inside and outside output shaft flange is carried out work, and the clutch end of transmission case body and power intake all are arranged on the transmission main box.
In like manner; A kind of transmission case body of saw blades groups circular sawing machine; Motor in the circular sawing machine body drives the transmission system in the transmission case body through the input with the joining transmission case body of body; The inside and outside output shaft that drive is arranged on the transmission case body output rotates with one heart and in opposite directions, drives a pair of suitable saw blades groups of the saw blade of rotation in opposite directions that contains that is clamped on the inside and outside output shaft flange and carries out work, and the output of transmission case body and input are one.
The advantage of the utility model is: the clutch end of transmission case body and power intake all are arranged on the transmission main tank main body, and both are integrative-structures.The accumulation of avoiding the branch body structure to produce two member mismachining tolerances reduces axially and radial error, improves transmission system works precision, and transmission system is carried out more steadily reliable.Improve the mechanical strength that the clutch end of transmission case body is connected with power intake simultaneously, the fixing also reliability more of blade shroud.
This saw blades groups circular sawing machine can be realized through the measure of describing in the following technical scheme and further improvement and perfect.
Interior output shaft flange and interior output shaft, both can be splits, also can be one.The interior output shaft flange and the interior output shaft that divide body structure, the difference in height of being convenient to regulate inside and outside output shaft flange; The interior output shaft flange and the interior output shaft of integrative-structure help improving the smoothness of saw blade.
Saw blades groups is made up of two saw blades.Two saw blades can be a pair of common saw blades, also can be that at interval facility is linked to a pair of common saw blade on the blade bodies of at least one saw blade.
Saw blades groups by two saw blades and at least a slice distance piece constitute.
Transmission system is a bevel gear tooth system.The motor axis in the body and the axis of inside and outside output shaft are orthogonal, realize deceleration transmission through bevel gear tooth system.
Description of drawings
Fig. 1 is the partial sectional view that the utility model saw blades groups circular sawing machine is optimized.Output shaft flange and interior output shaft among the figure, both illustrate with one; Transmission system illustrates with bevel gear tooth system; Saw blades groups with two saw blades and at least a slice distance piece illustrate.
The specific embodiment
Saw blades groups circular sawing machine (1) among Fig. 1; Transmission case body (4) is formed by connecting transmission main box (40) and the assembling of transmission-case cover (46) two parts; Motor (3) in the body (2) is through driving the transmission system (5) of (4) in the transmission case body with the power intake (4a) of the joining transmission case body of body (2) (4); Drive is arranged on one heart and the in opposite directions rotation of rotation (r) of inside and outside output shaft (10,20) of the clutch end (4b) of transmission case body (4), drives to be clamped in inside and outside output shaft flange (11; 21) contain a pair of suitable saw blade (31 of rotation in opposite directions on; 36) saw blades groups (30) is carried out work, and both all are arranged on the clutch end (4b) of transmission case body (4) and power intake (4a) on the transmission main box (40), are integrative-structures.The accumulation that integrative-structure avoids the branch body structure to produce two member mismachining tolerances reduces axially and radial error, improves transmission system works precision, and transmission system is carried out more steadily reliable.Improve the mechanical strength that the clutch end of transmission case body is connected with power intake simultaneously, the fixing also reliability more of blade shroud.
