Compared with the prior art, the tensioning device for the chain is simple in structure, and is reliable to run and convenient and quick to mount and maintain; when the chain generates plastic deformation to become long, the chain can be tensioned; an engagement angle between the chain and a sprocket wheel is corrected; and the normal running of chain transmission is guaranteed.
Description
Technical field
The present invention relates to the mechanical transmissioning technology field, relate in particular to a kind of chain stretching device.
Background technique
The chain transmission is one of modal kind of drive in the present machinery, and chaindriven figure is seen everywhere in the equipment such as crane gear, parking apparatus, passenger-goods lift, automobile, bicycle, toy or mechanism.Along with chaindriven frequent use, because the problem that the wearing and tearing of chain, sprocket wheel cause is also more and more, plastic deformation and then elongated can occur because chain is long-time after stressed, thereby also can jump tooth when serious, the phenomenon of falling chain causes transmission process to interrupt even have an accident.
Summary of the invention
The object of the present invention is to provide easily chain stretching device of a kind of simple in structure, reliable, installation and maintenance, securable chain when chain generation plastic deformation is elongated, revise the tooth matching angle between chain and the sprocket wheel, guarantee that the chain transmission normally moves, thereby solve the problem that prior art exists.
To achieve these goals, the invention provides a kind of chain stretching device, comprise upper holder block, C type frame, lower lock block, pressing tight plate and hold out against screw, the C type opening of two C type frames is oppositely arranged and forms a rectangular frame, and upper holder block is fixed on the inner and upper of rectangular frame; Pressing tight plate be positioned at upper holder block under be fixed in the inside below of rectangular frame; Lower lock block is installed in can be up and down in rectangular frame inside in the rectangular frame, and described lower lock block is between upper holder block and pressing tight plate, and lower lock block and upper holder block are oppositely arranged up and down; Hold out against screw and be arranged on the pressing tight plate, hold out against the screw top and be against on the lower lock block, be used for regulating the spacing between upper holder block and the lower lock block.
Described lower lock block both sides all offer guide groove, and the guide groove of both sides cooperates with the side of two C type frames respectively, and lower lock block can be up and down in rectangular frame inside along the side of two C type frames.
The side that described upper holder block is relative with lower lock block is respectively arranged with cambered way and rib, and described cambered way is according to the movement locus setting of chain.
Described upper holder block and lower lock block are nylon material and make.
The described screw that holds out against is two or more.
Thereby chain stretching device of the present invention is by the chain of the compression of the spacing between adjusting upper holder block and the lower lock block between upper holder block and lower lock block, and then the purpose of realization tension chain.Compared to prior art, chain stretching device of the present invention is simple in structure, reliable, installation and maintenance are convenient, and securable chain when chain generation plastic deformation is elongated is revised the tooth matching angle between chain and the sprocket wheel, guarantees that the chain transmission normally moves.
Description of drawings
Below in conjunction with the drawings and specific embodiments, structure and the useful technique effect thereof of chain stretching device of the present invention is elaborated.
Fig. 1 is that the master of the embodiment of the invention looks schematic diagram;
Fig. 2 is the side view of the embodiment of the invention;

Among the figure: 1, upper holder block; 2, C type frame; 3, set screw; 4, lower lock block; 5, pressing tight plate; 6, hold out against screw; 7, guide groove; 8, cambered way; 9, rib; 10, sprocket wheel; 11, chain.
Embodiment
Purpose of the present invention, technological scheme and useful technique effect are more clear to be understood in order to make, and below in conjunction with accompanying drawing technology contents of the present invention and embodiment is described in further detail.Should be understood that, the embodiment of describing in this specification only is in order to explain the present invention, is not in order to limit the present invention.
Referring to figs. 1 through shown in Figure 3, chain stretching device for the embodiment of the invention, described chain stretching device comprises upper holder block 1, C type frame 2, lower lock block 4, pressing tight plate 5 and holds out against screw 6, the C type opening of two C type frames 2 is oppositely arranged and forms a rectangular frame, and upper holder block 1 is fixed on the inner and upper of rectangular frame through set screw 3; Pressing tight plate 5 be positioned at upper holder block 1 under, be fixed in the inside below of rectangular frame through set screw 3.It is interior between upper holder block 1 and pressing tight plate 5 that lower lock block 4 is installed in rectangular frame, and lower lock block 4 and upper holder block 1 are oppositely arranged up and down.Described lower lock block 4 both sides all offer guide groove 7, and the guide groove 7 of both sides cooperates with the side of two C type frames 2 respectively, and lower lock block 4 can be up and down in rectangular frame inside along the side of two C type frames 2.Hold out against screw 6 and be arranged on the pressing tight plate 5, hold out against screw 6 tops and be against on the lower lock block 4, be used for regulating the spacing between upper holder block 1 and the lower lock block 4.
Upper holder block 1 and lower lock block 4 are nylon material and make, and upper holder block 1 is respectively arranged with cambered way 8 and rib 9 with lower lock block 4 relative sides, and described cambered way 8 is according to the movement locus setting of chain.
Figure 4 shows that chain stretching device is used for the work schematic diagram of tension chain, chain stretching device is installed between two sprocket wheels 10, chain 11 is stuck in the cambered way 8 of upper holder block 1 and lower lock block 4.When plastic deformations occur and fluff in chain 11, will hold out against and revolve relative pressing tight plate 5 on the screw 6 and move upward, hold out against screw 6 tops and be against on the lower lock block 4 thereby promote lower lock block 4 and move upward, thereby with chain 11 re-tensionings that fluff.Hold out against screw 6 and be two or more, tension effects is more stable.
