Abstract
The utility model relates to a kind of rotational structures with damping, including rotary shaft, and in pedestal, which is that threaded hole is arranged among cylindrical body and top；Bolt protrudes into rotary shaft interstitial hole by screw rod, is threadedly coupled with rotary shaft；Rotary sleeve is surrounded on the outer wall of rotary shaft, and relative rotation occurs with rotary shaft；Between the upper end and bolt head of rotary sleeve, and/or damping gasket is set between the lower end and pedestal of rotary sleeve, and damping gasket fitting and rotary shaft.The utility model generates frictional resistance, rotary shaft is allow arbitrarily to be parked in any position due to increasing damping gasket between damping gasket and pedestal and rotary shaft.
Description
Technical field
The utility model relates to fixed structure piece field, specifically a kind of rotational structure with damping.
Background technique
Rotary sleeve is the common mechanical structure of machinery field, cooperates with rotary shaft, carries out rotation work using bearing principle
Industry, but existing rotary shaft is difficult to stop rotating in rotation status, do not have between rotary sleeve and pedestal it is any contact, cannot do
Arbitrarily stop to rotary sleeve, it is controlled extremely difficult.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of rotational structure with damping, solve rotary shaft and
The problem of rotary sleeve cannot stop operating easily.
The utility model technical solution used for the above purpose is:
A kind of rotational structure with damping, the rotational structure include pedestal, the rotary shaft being installed on pedestal and with
It is set in outside the rotary shaft and can have hollow axocoel with the rotary sleeve of the rotary shaft relative rotation, the rotary shaft,
It further include bolt, the bolt includes screw rod and the nut that is fixedly connected with the screw rod, and the screw rod is detachably placed in institute
It states that hollow shaft is intracavitary, damping mat is installed between the upper end and nut of rotary sleeve and/or between the lower end and pedestal of rotary sleeve
Piece, the damping gasket fit in rotary shaft.
The damping gasket is annular gasket, and the damping gasket is set in outside the rotary shaft.
The rotary shaft and pedestal relative rotation.
The utility model has the advantages that and advantage:
Due to increasing damping gasket, frictional resistance is generated between damping gasket and pedestal and rotary shaft, makes rotary shaft can
To be arbitrarily parked in any position.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model；
1 it is wherein pedestal, 2 be rotary shaft, 3 be rotary sleeve, 4 be bolt, 5 is damping gasket.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.Many details are explained in the following description in order to abundant
Understand the utility model.But the utility model can be implemented in many other ways than those described herein, this field skill
Art personnel can do similar improvement without prejudice to utility model intension, therefore the utility model is not by following public
The limitation of specific implementation.
It should be noted that be referred to as " being set to " another element when element, it may directly on the other element,
Or there may also be elements placed in the middle.When an element is known as " connection " another element, it be can be directly connected to separately
One element may be simultaneously present centering elements.It is used herein to belong to "front", "rear", "left", "right" and similar
Statement for illustrative purposes only, be not offered as unique embodiment.
