Specific implementation mode
In order to allow the utility model features described above and advantage be clearer and more comprehensible, below spy for embodiment, and coordinate attached drawing,
It is described in detail below.
As shown in Fig. 1~5, a kind of eccentric correction device of front rolling drum of running exercising apparatus, including correction component 100, the correction
Component 100 is set to 210 one end of inner shaft (such as left part shown in figure) of front rolling drum of running exercising apparatus 200, the front roll
200 210 one end of inner shaft vertically offers threaded hole 211, the correction component 100 include adjusting screw 110,
Eccentric correction part 120 and holder 130, the eccentric correction part 120 vertically offer eccentric circular hole 121, the bias
The internal diameter of circular hole 121 is more than the outer diameter of adjusting screw 110, and positioning round orifice 131, the bias school are provided on the holder 130
The lower end of positive part 120 is stretched into positioning round orifice 131 and is rotatably coordinated, and the adjusting screw 110 passes through eccentric circular hole 121
It locks and coordinates with threaded hole 211 afterwards.
In the present embodiment, the eccentric correction part 120 is by the regular polygon prism 122 of upper end and determining for lower end
Circle of position column forms, and the eccentric circular hole 121 runs through regular polygon prism 122 and positioning cylinder 123, and the positioning cylinder 123 is
It is extended downwardly by the bottom centre of regular polygon prism 122, therefore 121 relative positioning cylinder 123 of eccentric circular hole is also off-centre operation,
The positioning cylinder 123 and 131 clearance fit of positioning round orifice so that eccentric correction part 120 can opposite brackets 130 positioning round orifice
131 rotations.Wherein, the regular polygon prism 122 with eccentric circular hole 121 is similar to eccentric nut, but without internal thread, it is described just
Polygon-prism 122 is preferably but not limited to hexagon.
In the present embodiment, the top surface of the eccentric correction part 120, which is provided with, is used to indicate 121 bias of eccentric circular hole on the contrary
The mark structure 124 in direction convenient for learning the rotation position and direction of eccentric correction part 120, and then is conveniently operated.Wherein, institute
It can be lug boss or recessed portion, triangular hill as shown in Figure 5 to state mark structure 124.Wherein, the eccentric circular hole 121
Eccentric distance data go to calculate in advance according to the characteristics of product itself.
In the present embodiment, 210 one end of inner shaft of the front roll 200 is provided with the flat position contacted with holder 130
212, with smoothly supporting support 130.Wherein, the holder 130 is fixed on the supporting rack of treadmill treadmill.
In the present embodiment, 210 the other end of inner shaft (such as right part shown in figure) of the front roll 200 passes through
Fixed screw 700 is lock onto on the supporting rack of treadmill treadmill.
In the present embodiment, the one end (such as right part shown in figure) of the front roll 200 passes through belt 300
It is connected with the output end of motor 400, the front roll 200 is connected by treadbelt 500 with back roll 600.It is of course also possible to
It is that the left part of front roll 200 is connected by belt 300 with the output end of motor 400, is carried out in the left part of front roll 200
After eccentric correction, then belt 300 is set to be in tensioning state by the position of regulation motor 400.
The operation principle of the present embodiment is as follows：When adjusting screw 110 passes through the spiral shell of eccentric correction part 120 and front roll 200
After pit 211 is locked, adjusting screw 110 is equal to one with roller, rotates (rotational trajectory with spanner (such as outer hexagonal spanner)
For the circular path of positioning round orifice 131) adjustment eccentric correction part 120 when；When rotating clockwise in a certain range, due to bias
Relationship, more than a, (a, b refer respectively to the center of circle of 120 rotational trajectory of eccentric correction part to partially to b in centainly rotation adjusting range
The shortest distance and longest distance of the circular path of heart circular hole 121), at this time due to the pulling force by the treadbelt 500 always existed
Effect, treadbelt 500 can draw front roll 200 toward 600 direction of back roll together with adjusting screw 110；When rotating certain angle counterclockwise
When spending, due to eccentric relationship, a is less than b in centainly rotation adjusting range, and eccentric correction part 120 can be adjusting screw at this time
110 push up together with front roll 200 toward 400 direction of motor.
Since the other end of front roll 200 is first locked by fixed screw 700, timing need to only pass through eccentric school
Positive part 120 pulls forward or toward post-tensioning adjusting screw 110, to make up the gradient of treadbelt 500.The present embodiment passes through eccentric correction part
120 make up existing error when the error and practical set of machining accuracy clockwise or counterclockwise, before reaching correction
The parallel purpose of roller 200, back roll 600 reaches the technical issues of solving 500 beat of treadbelt.
The above, the only preferred embodiment of the utility model, not do limit in any form to the utility model
System, any technical person familiar with the field is in every case without departing from the content of technical solutions of the utility model, according to the utility model
Technical spirit any simple modification, equivalent changes and modifications are made to above example, should all belong to the culvert of the utility model
Lid range.
