Abstract
The utility model discloses a kind of automatic takeup, it comprises motor, support, rocker, hole, axle and pedestal, the below of described motor is installed with support, described support is fixed on rocker, axle is through being fixed on pedestal by rocker behind the hole on rocker, and this tension device realizes automatic distance-adjusting, to the tensioning of driving belt by utilizing the weight of motor and rocker, and by attaching nut, locking is realized to rocker and pedestal, prevent rocking of whole device, good reliability, simultaneously, this automatic takeup structure is simple, and cost is low.
Description
Technical field
The utility model relates to the tension device of V belt translation, specifically a kind of automatic takeup.
Background technique
V belt translation utilizes the flexible-belt be stretched on belt wheel to carry out moving or a kind of mechanical transmission of transmission of power, it is simple that V belt translation has structure, stable drive, absorbing can be cushioned, can between large distance between shafts and multiaxis transferring power, and it is cheap, do not need lubrication, safeguard the features such as easy, apply very extensive in Modern Mechanical transmission, but, because load on axle is larger, the effect of driving belt long-term tension power, easy generation permanent deformation, driving belt length is increased, cause lax, cause the service life reduction of driving belt, this just needs to do regular tensioning to driving belt.
In V belt translation, take some maintain measures, to keep driving belt in tensioning state work, prior art adds Idle wheel in the inner side of Idle wheel, but like this centre distance is required just larger, if centre distance is little, but because driving belt creates permanent deformation, tensioning can not be carried out to driving belt by the method increasing Idle wheel, if do not change driving belt just can not work, change the words of driving belt, cost compare is high, therefore, this just needs a kind of when not changing the centre distance of driving belt, both can effective tensioning driving belt, the device of driving belt can not be changed again.
Model utility content
Model utility object: the purpose of this utility model is to solve the deficiencies in the prior art, provide a kind of structure simple, cost is low, the reliable automatic takeup of working stability.
Technological scheme: in order to realize above object, a kind of automatic takeup described in the utility model, it comprises motor, support, rocker, hole, axle and pedestal, the below of described motor is installed with support, and described support is fixed on rocker, and rocker is fixed on pedestal through behind the hole on rocker by axle.
As of the present utility model preferred further, described rocker is provided with a plane of inclination, this plane of inclination is positioned at the bottom of rocker, when driving belt produces permanent deformation, when needing to carry out tensioning to it, motor can be automatically sagging according to its deadweight, rocker is designed to plane of inclination, more can utilizes driving belt.
Further preferably be provided with centre distance between described pedestal and motor as of the present utility model, as of the present utility model preferred further, described centre distance size is 30% ~ 45% of motor diameter.
As of the present utility model preferred further, the right side of described axle is provided with attaching nut, and the right side of attaching nut is provided with nut end, and be provided with internal thread in the hole that rocker is provided with, attaching nut is provided with outside thread.After axle is through the hole on rocker, rocker is fixed on after on pedestal, driving belt is set in the outside of motor, because the rotation of motor can produce peripheral force, cause rocking of whole support and rocker, therefore, by attaching nut through hole and pedestal, make the internal thread locking on the outside thread on attaching nut and rocker and pedestal fastening, overcome rocking of producing because of electric machine rotation.When driving belt produces permanent deformation, after causing the phenomenon of skidding to occur, only nut end need be unclamped, attaching nut is exited from rocker and pedestal, motor is tilted because of deadweight, carry out spacing by driving belt to motor, and then by fastening for the internal thread locking on the outside thread on attaching nut and rocker and pedestal, the tensioning of driving belt can be realized.
beneficial effect
A kind of automatic takeup that the utility model provides, automatic distance-adjusting is realized by utilizing the weight of motor and rocker, to the tensioning of driving belt, and by attaching nut, locking is realized to rocker and pedestal, prevent rocking of whole device, good reliability, simultaneously, this automatic takeup structure is simple, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of the joint of rocker and pedestal.
Embodiment
Below in conjunction with accompanying drawing, illustrate the utility model further.
Be illustrated in figure 1 a kind of automatic takeup described in the utility model, it comprises motor 1, support 2, rocker 3, hole 30, axle 31 and pedestal 4.
The below of motor 1 is installed with support 2, and described support 2 is fixed on rocker 3, and rocker 3 is fixed on pedestal 4 through behind the hole 30 on rocker 3 by axle 31.Rocker 3 is provided with a plane of inclination 34, plane of inclination 34 is positioned at the bottom of rocker 3, the right side of axle 31 is provided with attaching nut 32, the right side of attaching nut 32 is provided with nut end 33, internal thread is provided with in the hole 30 that described rocker 3 is provided with, attaching nut 32 is provided with outside thread, is provided with centre distance between pedestal 4 and motor 1, and centre distance size is 30% ~ 45% of motor diameter.
Because the rotation of motor 1 can produce peripheral force, cause rocking of whole support 2 and rocker 3, therefore, as shown in Figure 2, by attaching nut 32 through hole 30 and pedestal 4, make the internal thread locking on the outside thread on attaching nut 32 and rocker 3 and pedestal 4 fastening, overcome rocking of producing because motor 1 rotates.When driving belt produces permanent deformation, after causing the phenomenon of skidding to occur, only need unclamp nut end 33, attaching nut 32 is exited from rocker 3 and pedestal 4, motor 1 is tilted because of deadweight, carry out spacing by driving belt to motor 1, and then by fastening for the internal thread locking on the outside thread on attaching nut 32 and rocker 3 and pedestal 4, the tensioning of driving belt can be realized, after unclamping nut end 33, motor 1 tilts, and rocker 3 is along with after motor 1 tilts because of deadweight, if after the plane of inclination 34 on rocker 3 and earth surface, then need to change driving belt.
Above-mentioned embodiment, only for technical conceive of the present utility model and feature are described, its objective is to allow and is familiar with these those skilled in the art and can understands content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalents of making according to the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
