Abstract
The utility model is related to plate cutting apparatus technical fields, more particularly to a kind of accurate multiple blade saw chain drive axle construction, driving sleeve and sprocket wheel are sleeved on transmission shaft, sprocket wheel is fixedly connected with driving sleeve, it is connected by middle font spline structure between transmission shaft and sprocket wheel, the first groove on middle font spline structure and the second groove, it is not directly to be processed in circular sprocket wheel inner ring, but sprocket wheel inner ring is first increased into two pieces of symmetrical platforms and forms kidney-shaped endoporus, the first groove and the second groove are opened up respectively on two platforms again, so that sprocket wheel and transmission shaft driven are stablized, it is durable.It avoids because directly when sprocket wheel inner ring processes the first groove and the second groove, inconvenient phenomenon is processed in the relatively thin appearance of sprocket wheel inner wall.
Description
Technical field
The utility model is related to plate cutting apparatus technical field more particularly to a kind of accurate multiple blade saw chain transmission axle knots
Structure.
Background technology
Material is mainly sawn into splintery by multi-disc saw equipment, and multi-disc saw equipment includes necessarily drive apparatus, such as is driven
Axis band movable sprocket rotates, and by key connection between transmission shaft and sprocket wheel, since the sprocket wheel inner wall of multiple blade saw is relatively thin, then does at fluting
Reason is used for installation key, and difficulty of processing is larger, and stability is not high.
Utility model content
The technical problems to be solved in the utility model is：In order to solve thin-wall part fluting difficulty of processing in existent technique
Greatly, the not high technical problem of stability, the utility model provide a kind of accurate multiple blade saw chain drive axle construction.
Technical solution adopted by the utility model to solve its technical problems is：A kind of precision multiple blade saw chain transmission axle knot
Structure, including transmission shaft, sprocket wheel and driving sleeve, the driving sleeve and sprocket wheel are sleeved on transmission shaft, sprocket wheel and transmission shaft
Set is fixedly connected, and is connected by middle font spline structure between transmission shaft and sprocket wheel.
Further, specifically, the middle font spline structure is to be machined on transmission shaft mutually in 180 ° symmetrical first
Key and the second key, being provided with for integral structure is mutually in 180 ° of symmetrical first platforms and the second platform on sprocket wheel inner ring, and first
Offer the first groove on platform, offer the second groove, the first key and the first fit depressions on the second platform, the second key and
Second fit depressions.The first groove on middle font spline structure and the second groove are not directly in circular sprocket wheel inner ring
Processing, but sprocket wheel inner ring is first increased into two pieces of symmetrical platforms so that sprocket wheel inner ring forms kidney-shaped endoporus, then flat
The first groove and the second groove are opened up on platform, are avoided directly in sprocket wheel inner ring the first groove of processing and the second groove, sprocket wheel
Wall is relatively thin to there is the inconvenient phenomenon of processing.
The rectangular groove in the both sides of first key and the both sides of the second key.First key is by being processed on transmission shaft
Two symmetrical right angle grooves form the first key, the processing method of the second key and the first key between two symmetrical right angle grooves
It is identical.
The utility model has the beneficial effects that the accurate multiple blade saw chain drive axle construction of the utility model, middle font flower
The first groove on bond structure and the second groove are not directly to be processed in circular sprocket wheel inner ring, but first will be in sprocket wheel
Circle increases by two pieces of symmetrical platforms and forms kidney-shaped endoporus, then opens up on two platforms the first groove and second recessed respectively
Slot so that sprocket wheel and transmission shaft driven are stablized, durable.It avoids because directly processing the first groove and the second groove in sprocket wheel inner ring
When, sprocket wheel inner wall is relatively thin to there is the inconvenient phenomenon of processing.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the dimensional structure diagram of the utility model precision multiple blade saw chain drive axle construction.
Fig. 2 is the front view of the utility model precision multiple blade saw chain drive axle construction.
Fig. 3 is the right view of the utility model precision multiple blade saw chain drive axle construction.
In figure：1, transmission shaft, the 11, first key, the 12, second key, 13, right angle groove, 2, sprocket wheel, the 21, first platform, 22,
Second platform, the 23, first groove, the 24, second groove, 3, driving sleeve.
Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figs. 1-3, it is the utility model optimum embodiment, a kind of precision multiple blade saw chain drive axle construction, including
Transmission shaft 1, sprocket wheel 2 and driving sleeve 3, driving sleeve 3 and sprocket wheel 2 are sleeved on transmission shaft 1, and sprocket wheel 2 and driving sleeve 3 are solid
Fixed connection, is connected between transmission shaft 1 and sprocket wheel 2 by middle font spline structure, and middle font spline structure is：Add on transmission shaft 1
It is in 180 ° of 11 and second keys 12 of symmetrical first key that work, which has mutually, and being provided with for integral structure is mutually in 180 ° on 2 inner ring of sprocket wheel
21 and second platform 22 of symmetrical first platform offers the first groove 23 on the first platform 21, is offered on the second platform 22
Second groove 24, the first key 11 and the first groove 23 match, and the second key 12 and the second groove 24 match, sprocket wheel 2 and transmission
Axle sleeve 3 is fixed, and can be moved along axis, the both sides of the both sides of the first key 11 and the second key 12 rectangular groove 13.
The first groove 23 on middle font spline structure and the second groove 24 are not directly to add in 2 inner ring of circular sprocket wheel
Work, but it is in 180 ° of symmetrical platforms that 2 inner ring of sprocket wheel, which is first integrally machined two pieces of increase mutually, so that 2 inner ring of sprocket wheel is formed
Kidney-shaped endoporus, then open up the first groove 23 and the second groove 24 respectively on platform, it avoids because directly being processed in 2 inner ring of sprocket wheel
When the first groove 23 and the second groove 24,2 inner wall of sprocket wheel is relatively thin to there is the inconvenient phenomenon of processing.
First key 11 is by processing two symmetrical right angle grooves 13, two symmetrical right angles on transmission shaft 1
The first key 11 is formed between groove 13, the second key 12 is identical with the processing method of the first key 11.First key 11 and the second key 12 are
It is integral structure with transmission shaft 1.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to which its technology is determined according to right
Property range.
