Abstract
The utility model discloses a kind of supervisor change-speed gear chain block, for preventing gearbox inner driving system bar scratching gear box casing, be arranged at the both sides place being positioned at described drive chain inside gear box casing, comprise the stop block body that elastic material is made, described stop block body is outer convex arc edge near the side of described drive chain, is provided with fixing device between described stop block body and described gear box casing.When drive chain loosens in transmission process, the expanding force to drive chain effectively can be formed by stop block body, thus avoid drive chain to shake, drive chain and the mutual scratching of gear box casing can be prevented, not only be beneficial to the noise reducing chain transmission process and produce, and be beneficial to gearbox stable operation.Meanwhile, stop block body adopts elastic material to make, and not only fabricating cost is cheap, but also has advantage lightweight, that volume is little, easy for installation.
Description
Technical field
The utility model relates to a kind of gearbox transmission technical field, particularly relates to a kind of supervisor change-speed gear chain block.
Background technique
Existing garden supervisor, gearbox is overlapped in usual employing two, a set of is moving gear box, the power speed changing of motor is passed to walking pto＝power take-off by Chain conveyer or gear transmission, another set of is work gear-box, it or from motor or from walking pto＝power take-off obtain power, then power is exported to operation pto＝power take-off by Chain conveyer or gear transmission.Chain drive structure effectively can reduce the quantity of gear, alleviates the weight of gearbox, reduces manufacture cost, but because chain is longer, in transmission process, chain can produce concussion, and even easily scratching produces various noise to gear box casing, therefore awaits further improvement.
Model utility content
It is cheap that technical problem to be solved in the utility model is to provide a kind of fabricating cost, can avoid chain scratching gear box casing in gearbox thus reduce noise, being beneficial to the supervisor change-speed gear chain block that gearbox is stable.
For solving the problems of the technologies described above, the technical solution of the utility model is: supervisor change-speed gear chain block, for preventing gearbox inner driving system bar scratching gear box casing, be arranged at the both sides place being positioned at described drive chain inside gear box casing, comprise the stop block body that elastic material is made, described stop block body is outer convex arc edge near the side of described drive chain, is provided with fixing device between described stop block body and described gear box casing.Wherein, elastic material can select rubber, haloflex etc. to have certain degree of hardness and the good elastomeric material of wear resistance, is beneficial to and increases the service life.
As preferred technological scheme, described fixing device comprises two fixing columns be provided with inside described gear box casing, and described stop block body is provided with the fixed hole suitable with described fixing column.
As the improvement to technique scheme, described stop block body is imploded arcs edge away from a middle side part of described drive chain.
As the improvement to technique scheme, described stop block body is positioned at described outer convex arc edge side and is provided with the arcuation tensioner ridge adapted with described drive chain.
As the further improvement to technique scheme, described stop block body two be arranged with supporting projections respectively on the surface up and down.
Owing to have employed technique scheme, supervisor change-speed gear chain block, for preventing gearbox inner driving system bar scratching gear box casing, be arranged at the both sides place being positioned at described drive chain inside gear box casing, comprise the stop block body that elastic material is made, described stop block body is outer convex arc edge near the side of described drive chain, is provided with fixing device between described stop block body and described gear box casing; The utility model has following beneficial effect: when drive chain loosens in transmission process, the expanding force to drive chain effectively can be formed by stop block body, thus avoid drive chain to shake, drive chain and the mutual scratching of gear box casing can be prevented, not only be beneficial to the noise reducing chain transmission process and produce, and be beneficial to gearbox stable operation.Meanwhile, stop block body adopts elastic material to make, and not only fabricating cost is cheap, but also has advantage lightweight, that volume is little, easy for installation.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:
Fig. 1 is the installation assembling schematic diagram of the utility model embodiment;
Fig. 2 is I place partial enlarged drawing in Fig. 1;
Fig. 3 is the schematic top plan view of stop block body;
Fig. 4 be in Fig. 3 A-A to sectional structure schematic diagram.
In figure: 100-gear box casing; 200-drive chain; 300-stop block body; 310-fixed hole; The outer convex arc edge of 320-; 330-imploded arcs edge; 340-supporting projections; 350-tensioner ridge.
Embodiment
Below in conjunction with drawings and Examples, set forth the utility model further.In the following detailed description, the mode only by illustrating describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art can recognize, when not departing from spirit and scope of the present utility model, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, supervisor change-speed gear chain block, for preventing gearbox inner driving system bar 200 scratching gear box casing, be arranged at the both sides place being positioned at described drive chain 200 inside gear box casing 100, comprise the stop block body 300 that elastic material is made, described stop block body 300 is designed to outer convex arc edge 320 near the side of described drive chain 200, described stop block body 300 is positioned at described outer convex arc edge 320 side and is provided with the arcuation tensioner ridge 350 adapted with described drive chain 200, fixing device is provided with between described stop block body 300 and described gear box casing 100.Wherein, stop block body 300 preferably selects rubber, haloflex etc. to have the elastomeric material of certain degree of hardness, and not only wear resistance is good, is beneficial to and increases the service life, and can reduce and the noise produced during drive chain scratching.
Fixing device described in the present embodiment comprises two fixing columns be provided with inside described gear box casing 100, described stop block body 300 is provided with the fixed hole 310 suitable with described fixing column, decoration structure features simple design, it is simple, convenient not only to install, and is beneficial to saving transmission housing intracorporeal space.
With reference to figure 1 and Fig. 2, in order to improve the support expanding force of stop block body 300, save material, best described stop block body 300 is designed to imploded arcs edge 330 away from a middle side part of described drive chain 200 simultaneously.Meanwhile, in order to support convenient fixing, firm, described stop block body 300 two be arranged with supporting projections 340 respectively on the surface up and down.
When drive chain loosens in transmission process, the expanding force to drive chain 200 effectively can be formed by stop block body 300, thus avoid drive chain 200 to shake, drive chain 200 and gear box casing 100 scratching mutually can be prevented, not only be beneficial to the noise reducing chain transmission process and produce, and be beneficial to gearbox stable operation.Stop block body 300 adopts rubber material to make, lightweight, volume is little, easy for installation, fabricating cost is cheap.
The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
