Abstract
The invention discloses a wheel set of a self-weight treadmill. The wheel set comprises a fixed axle, an axle tube and driving wheels, wherein the fixed axle is fixed on a chassis of the treadmill; the axle tube sleeves the outer side of the fixed axle, and the inner sides of two ends of the axle tube are respectively in running fit with two ends of the fixed axle by bearings; the driving wheels are fixed at the outer side of the axle tube. According to the wheel set of the self-weight treadmill, the inner sides of the two ends of the axle tube are in running fit with the fixed axle, and the driving wheels are fixed at the outer side of the axle tube, so that the two driving wheels on the same fixed axle are fixed relative to the axle tube, and the movement of the driving wheels at the two ends of the fixed axle is synchronized. Furthermore, the fixed axle is directly fixed on the chassis instead of being arranged in a way of running fit, so that the higher requirements for the processing accuracy of the chassis of the treadmill are avoided, and the increment of the production cost is further avoided. In addition, the invention also discloses the self-weight treadmill.
Description
Technical field
The present invention relates to treadmill technical field, more particularly, to a kind of deadweight treadmill and its wheel group.
Background technology
Deadweight treadmill is no-power treadmill again, because movement locus itself is arc, mid portion is minimum, in front and back
Part be higher than all mid portion so that when moving, when riding in front region, treadmill can accelerate, when riding
During back region, treadmill meeting retarded motion is until stop.But current deadweight treadmill adopts drive to pass through bearing mostly
The mode being connected with fixing axle, the rotation that this kind of mode is relatively fixed axle due to the drive of the left and right sides is unrelated, left and right
Easily appearance is asynchronous for rotation, and therefore treadmill interim card easily when running, and also has for the service life of treadmill belt
Impact；Another is directly fixedly connected with axle for drive, and axle is rotated with the underframe of treadmill and is connected, although this kind of mode reality
The rotation having showed left and right drive is synchronous, because axle and underframe are that rotation is connected, therefore for underframe requirement on machining accuracy relatively
Height, increases production cost significantly.
In sum, how to solve the drive nonsynchronous problem of rotation of running wheel group of conducting oneself with dignity, it has also become this area
Technical staff's technical barrier urgently to be resolved hurrily.
Content of the invention
It is an object of the invention to provide a kind of deadweight treadmill and its wheel group, to solve the drive of running wheel group of conducting oneself with dignity
Rotate nonsynchronous problem.
To achieve these goals, the running wheel group the invention provides one kind is conducted oneself with dignity, comprising:
It is fixed on the fixing axle on treadmill underframe；
It is set in the central siphon outside described fixing axle, the inner side at described central siphon two ends passes through the two of bearing and described fixing axle
End is rotatably assorted；
It is fixed on the drive in the outside of described central siphon.
Preferably, at least one described bearing is unilateral bearing, and the outer ring of described unilateral bearing and described central siphon is interior
Side is fixedly connected, and the inner ring of described unilateral bearing is fixedly connected with described fixing axle.
Preferably, it is additionally provided with unilateral bearing between described central siphon and described fixing axle, and the outer ring of described unilateral bearing
It is fixedly connected with the inner side of described central siphon, the inner ring of described unilateral bearing is fixedly connected with described fixing axle.
Preferably, it is fixedly connected by the first key between described unilateral bearing and described fixing axle.
Preferably, described first key is flat key.
Preferably, described drive is fixed on described central siphon by straight pin.
Preferably, described drive and described central siphon are to be welded to connect.
Preferably, the outer ring of described bearing and described central siphon interference fit, the inner ring of described bearing with described fixing axle is
Gap coordinates.
Introduce content compared to background technology, above-mentioned deadweight running wheel group, by inner side and the fixing axle at central siphon two ends
It is rotatably assorted, drive is fixed on the outside of central siphon, two drives in therefore same fixing axle are solid relative to central siphon
Fixed, and then the motion of the drive at fixing axle two ends is synchronization.What fixing axle adopted simultaneously is directly anchored on underframe
It is provided without the mode being rotatably assorted, therefore avoid the high requirement of the machining accuracy of the underframe to treadmill, and then avoid
The increase of production cost.
In addition, present invention also offers a kind of deadweight treadmill, this deadweight treadmill includes running wheel group of conducting oneself with dignity, and is somebody's turn to do
Deadweight running wheel group is the deadweight running wheel group described by any of the above-described scheme.Because above-mentioned deadweight running wheel group has
Above-mentioned technique effect, the deadweight treadmill therefore with above-mentioned deadweight running wheel group also should have corresponding technique effect,
This repeats no more.
