Abstract
A kind of gripper machine tensioning wheel, including sprocket wheel and fixing device, the boss formed with the fixation sprocket wheel in the fixing device are the utility model is related to, the boss is replaced by bearing, and its outer ring external diameter matches with boss external diameter, is connected with the fixing device.The utility model, which can effectively avoid the occurrence of abrasion between sprocket wheel and boss, causes the phenomenon of chain-loose, service life length.
Description
Technical field
Gripper machine structural elements technology is the utility model is related to, specifically discloses a kind of gripper machine tensioning wheel.
Background technology
Gripper machine controls the elastic of chain by chain drive with tensioning wheel is shared；Wherein tensioning wheel includes sprocket wheel and fixation
Device (such as Fig. 1, its middle sprocket are not drawn into), integrated molding has boss on the securing means, and sprocket wheel is sleeved on boss, both
Relative motion；This structure causes sprocket wheel eccentric, further led for a long time using wear phenomenon occurs between sprocket wheel and boss
Cause chain-loose that mechanical breakdown occurs；It is troublesome in poeration and replacing tensioning wheel needs to tear machine open, influence operating efficiency and increase is produced into
This.
Utility model content
Goal of the invention of the present utility model is：A kind of gripper machine tensioning wheel is provided to solve problem above, it can have
Effect, which avoids the occurrence of abrasion between sprocket wheel and boss, causes the phenomenon of chain-loose, service life length.
Technical scheme is such used by the utility model：
Gripper machine tensioning wheel, including sprocket wheel and fixing device, formed with the fixation sprocket wheel in the fixing device
Boss；The boss is replaced with bearing, and its outer ring external diameter matches with boss external diameter, is connected with the fixing device.
Further, the small boss concentric with the boss is provided with the fixing device, its external diameter and the axle
The matching of inner ring internal diameter is held, is connected with bearing fit.
In summary, due to being using above-mentioned technical proposal, the beneficial effects of the utility model：
The utility model replaces boss with bearing, increases bearing really between boss and sprocket wheel, when effectively can prevent long
Between using causing occur wear phenomenon between sprocket wheel and boss, preventing chain and being sent to causes mechanical breakdown；Service life is grown, and protects
Demonstrate,prove normal operating efficiency.
Brief description of the drawings
Fig. 1 is the utility model prior art construction figure；
Fig. 2 is the utility model structure chart；
Fig. 3 is the utility model structural side view.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As Figure 2-3, gripper machine tensioning wheel, including sprocket wheel and fixing device 1, are formed in the fixing device 1
There is the boss 2 of the fixed sprocket wheel；The boss 2 is replaced with bearing 3, and its outer ring external diameter matches with the external diameter of boss 2, and described solid
Determine device 1 to connect；It can so ensure that the dimensional structure of the sprocket wheel of selection is constant.
The small boss 4 concentric with the boss 2, its external diameter and the inner ring of bearing 3 are provided with the fixing device 1
Internal diameter matches, and is connected with bearing 3；The outside dimension for really reducing former boss 2 is small boss 4, then sprocket wheel with it is small
Bearing 3 is added among boss 4, so can effectively reduce the friction between sprocket wheel and boss 2, reduces abrasion, ensures normal production.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
