Abstract
The invention provides an adjustable tensioning mechanism which is simple in structure, low in cost and convenient to adjust and is used for drive systems of equipment like farm machines. The adjustable tensioning mechanism is used for drive systems adopting belt drive, and comprises an engine rack for fixing an engine and a machine frame for installation of a driven shaft. The adjustable tensioning mechanism is characterized in that the bottom end of the engine rack is provided with two parallel guide pipes, the machine frame is provided with guide columns penetrating through the guide pipes, a rotary screw rod is arranged at the position, between the two guide columns, of the machine frame, a nut screwed to the screw rod is fixed to the bottom end of the engine rack, and the axial direction of the screw rod is parallel to the plane where a belt is located. The engine rack can move along the machine frame by means of the screw rod and the corresponding guide mechanisms, so that the belt is kept in the tensioned state all the time, adjustment is rather convenient, and the adjustable tensioning mechanism has good practicability and commercial value.
Description
Technical field
The invention belongs to technical field of agricultural machinery, be related specifically to a kind of adjustable tensioning mechanism.
Background technique
Along with the development of science and technology, the popularity rate of farm machinery is more and more higher, and the reliability of peasant to farm machinery it is also proposed higher requirement.Wherein, in farm machinery, requisite driving mechanism generally adopts cheap belt, but it is lax that belt there will be to a certain degree after long-time use, affects normal transmission.
Summary of the invention
The object of the invention is to propose the adjustable tensioning mechanism that a kind of structure is simple, cost is low, easy to adjust, for the transmission system of the equipment such as farm machinery.
Adjustable tensioning mechanism of the present invention is applied to and adopts in bel-drivenn transmission system, and comprise for the engine stand of stationary engine and the frame for installing driven shaft, key is that the bottom of described engine stand is provided with two parallel guide pipes; Described frame is provided with the directional post through described guide pipe; Described frame is also provided with rotating screw rod between two directional posts, and the bottom of described engine stand is fixed with the nut be threaded onto on described screw rod; Described screw rod be axially parallel to belt place plane.
During turn screw rod, can coordinating by screw rod and nut, the rotation of screw rod is converted into the rectilinear movement of engine stand along directional post, the tensioning degree of belt will be changed like this.When belt becomes lax because of the reason self used for a long time, only need rotating screw bolt, belt just can be made to keep tensioning, thus avoid transmission failure.Because screw rod has the characteristic of self-locking, therefore engine stand and frame can not the relative movements voluntarily when screw rod does not rotate.
Further, described frame is also provided with the fixing groove parallel with directional post, the position that described engine stand fixes groove in correspondence is provided with fixed plate, and described fixed plate is provided with through hole, and described engine stand and frame are by fixing through the bolt of through hole and fixing groove.When needing the tensioning degree regulating belt, first unclamp bolt, and then rotating screw bolt; After to be adjusted, then by bolt tightening, engine stand and frame are fixed together by auxiliary threaded rod.
Adjustable tensioning mechanism of the present invention enables engine stand along machine frame movement by screw rod and corresponding guide mechanism, thus belt is remained tensioning state, and adjusts very convenient, has good practicability and commercial value.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram (plan view) of adjustable tensioning mechanism of the present invention.
Fig. 2 is the mounting structure schematic diagram (side view) of adjustable tensioning mechanism of the present invention.
Accompanying drawing indicates: 1, frame; 11, directional post; 12, screw rod; 13, fixing groove; 2, engine stand; 21, guide pipe; 22, fixed plate; 3, bolt.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and working principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
(in Fig. 2, do not draw fixing groove, fixed plate and bolt) as shown in Figure 1, 2, the adjustable tensioning mechanism of the present embodiment is applied to and adopts in bel-drivenn transmission system, comprise for the engine stand 2 of stationary engine and the frame 1 for installing driven shaft, key is that the bottom of described engine stand 12 is provided with two parallel guide pipes 21; Described frame 1 is provided with the directional post 11 through described guide pipe 21; Described frame 1 is also provided with rotating screw rod 12 between two directional posts 11, and the bottom of described engine stand 12 is fixed with the nut be threaded onto on described screw rod 12; Described screw rod 12 be axially parallel to belt place plane.
During turn screw rod 12, can coordinating by screw rod 12 and nut, the rotation of screw rod 12 is converted into the rectilinear movement of engine stand 12 along directional post 11, the tensioning degree of belt will be changed like this.When belt becomes lax because of the reason self used for a long time, only need rotating screw bolt 12, belt just can be made to keep tensioning, thus avoid transmission failure.Because screw rod 12 has the characteristic of self-locking, therefore engine stand 12 and frame 1 can not the relative movements voluntarily when screw rod 12 does not rotate.
Frame 1 is also provided with the fixing groove 13 parallel with directional post 11, the position that described engine stand 12 fixes groove 13 in correspondence is provided with fixed plate 22, described fixed plate 22 is provided with through hole, and described engine stand 12 and frame 1 are by fixing through the bolt 3 of through hole and fixing groove 13.When needing the tensioning degree regulating belt, first unclamp bolt 3, and then rotating screw bolt 12; After to be adjusted, then tightened by bolt 3, engine stand 12 and frame 1 are fixed together by auxiliary threaded rod 12.
