Abstract
The utility model discloses a spiral adjustable belt pulley, including tight pulley piece, mounting flange, running wheel piece, spacing hole and screw, the beneficial effects of the utility model are that: the external screw thread of tight pulley piece can match the meshing with the inboard internal thread of running wheel piece is in the same place, the follower adopts the design of tight pulley piece and running wheel piece disconnect -type like this, helix group closes together through the screw thread, can through adjust the screw thread interlock what, and then it is big or small to adjust the follower, finally change the rotational speed, the screw can be adjusted according to distance between tight pulley piece and the running wheel piece, can carry on spacingly to tight pulley piece and running wheel piece through the screw like this, thereby can prevent the tight emergence rotation of the screw thread of tight pulley piece and running wheel piece like this and cause the not hard up condition, normal and the safe operation of assurance equipment, tight pulley piece and running wheel piece and belt laminating department are provided with netted decorative pattern, can increase the frictional force between belt and the belt pulley like this, guarantee the transmission effect.
Description
Technical field
The utility model relates to a kind of belt pulley equipment, is specially a kind of spiral adjustable straps wheel, belongs to technical field of mechanical equipment.
Background technique
Belt pulley is a kind of equipment realizing remote transmission power, on original belt pulley, when driving wheel rotating speed is constant, want the rotating speed changing driven wheel, cannot realize, such as on existing traditional farm machinery, when driving wheel and driven wheel are fixed, rotating speed is fixing, existing demand can not be met, when for different crops, need to adopt different rotating speeds, lead agency, carry out operation, thus reach best effect, but use existing belt pulley to be difficult to realize, and existing belt pulley does not have traction aid, be easy between such belt pulley and belt relative sliding occurs, thus larger frictional heat can be produced, affect the performance of belt, substantially reduce the working life of belt.
Model utility content
The purpose of this utility model is just to provide a kind of spiral adjustable straps wheel to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of spiral adjustable straps wheel, comprise fast pulley sheet, mounting flange, castor sheet, spacing hole and screw, it is characterized in that: described fast pulley sheet side and mounting flange are fixed together, described fast pulley sheet be provided with outside thread away from mounting flange side, internal thread is provided with inside described castor sheet, described fast pulley sheet and castor sheet are all symmetrically arranged with multiple spacing hole running through fast pulley sheet and castor sheet, and described screw is arranged in spacing hole.
Preferably, the internal thread inside the outside thread of described fast pulley sheet and castor sheet can mate and meshes together.
Preferably, described screw can adjust according to the spacing of fast pulley sheet and castor sheet.
Described spacing hole is identical with the quantity of described screw, and the number at least two of screw
The beneficial effects of the utility model are: this spiral adjustable straps wheel is reasonable in design, internal thread inside the outside thread of fast pulley sheet and castor sheet can mate and meshes together, such driven wheel adopts the design of fast pulley sheet and castor sheet separated type, be grouped together by thread helix, can by regulating threaded engagement how many, and then regulate driven wheel size, final change rotating speed, screw can adjust according to the spacing of fast pulley sheet and castor sheet, can carry out spacing to fast pulley sheet and castor sheet by screw like this, the screw thread of fast pulley sheet and castor sheet can be prevented so not tight thus rotate and cause loosening situation, normal and the safe operation of guarantee equipment, fast pulley sheet and castor sheet and belt are fitted the frictional force that can increase like this between belt and belt pulley, ensure transmission effect.

In figure: 1 fast pulley sheet, 2, mounting flange, 3, castor sheet, 4, spacing hole and 5, screw.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, a kind of spiral adjustable straps wheel, comprise fast pulley sheet 1, mounting flange 2, castor sheet 3, spacing hole 4 and screw 5, described fast pulley sheet 1 side and mounting flange 2 are fixed together, side away from mounting flange 2 is provided with outside thread to described fast pulley sheet 1, internal thread is provided with inside described castor sheet 3, internal thread inside the outside thread of described fast pulley sheet 1 and castor sheet 3 can mate and meshes together, such driven wheel adopts the design of fast pulley sheet 1 and castor sheet 3 separated type, be grouped together by thread helix, can by regulating threaded engagement, and then regulate driven wheel size, final change rotating speed, described fast pulley sheet 1 and castor sheet 3 and belt laminating, the frictional force between belt and belt pulley can be increased like this, ensure transmission effect, described fast pulley sheet 1 and castor sheet 3 are all symmetrically arranged with multiple spacing hole 4 running through fast pulley sheet 1 and castor sheet 3, described screw 5 is arranged in spacing hole 4, described screw 5 can adjust according to the spacing of fast pulley sheet 1 and castor sheet 3, can be undertaken spacing by screw 5 pairs of fast pulley sheets 1 and castor sheet 3 like this, described spacing hole 4 is identical with the quantity of described screw 5, and the number of screw 5 at least two, the screw thread of fast pulley sheet 1 and castor sheet 3 can be prevented so not tight thus rotate and cause loosening situation, normal and the safe operation of guarantee equipment.
Working procedure: when using described spiral adjustable straps wheel, first, mounting flange is arranged on by screw on the device of required transmission, then castor sheet and fast pulley sheet are grouped together by thread helix, according to required rotating speed size, regulate threaded engagement how much to reach appropriate position, and the spacing hole of castor sheet and fast pulley sheet is alignd, install screw-driving, then on driving wheel and driven wheel, load onto belt.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
