Abstract
The utility model relates to an external engagement roller chain wheel driving device. The utility model adopts a standard roller chain which is installed on an annular external side with a lug boss to form a roller chain wheel to complete external engagement driving with a standard chain wheel to realize driving with high driving ratio by lower cost. The utility model has the advantages of convenient fabrication, flexible installing mode and accurate average driving ratio. The utility model can be used for occasions of medium and small load and high driving ratio.
Description
The utility model belongs to the manufacturing technology of mechanical transmission component.
Existing gear drive generally is to design and produce according to the technical requirements of using, and says in a sense, reach the purpose of deceleration or speedup, nothing more than being realized by the gear of various parameters, different shape.Manufacturing technology, material requirements, production and processing difficulty height, expense are big comparatively speaking, if in practicality, only require the accurate and very big occasion of velocity ratio of average ratios, the manufacture cost of gearwheel is very high, and only for solving the purpose of speedup and deceleration, just seem quite uneconomical, bring inconvenience for user and producer.
It is accurate that the purpose of this utility model is just providing a kind of average ratios, can realize the big speed ratio transmission, and novel outer gearing roller chain wheel transmission device reliable, low cost of manufacture, substitutes gear fully in certain occasion and rotate.
The utility model, it is characterized in that its employing standard roller chain, be installed in the annulus outer side surface of a band boss, make roller chain wheel, it can finish the outer gearing transmission with standard sprocket, realizes the big speed ratio transmission with lower cost, also annulus can be processed into the disk of axis hole, the roller chain wheel transmission device is rotated around fixed center, reach practical purpose.
In order to narrate conveniently, the utility model is explained as follows:
Accompanying drawing 1 is a structural representation of the present utility model: (1) clamping bolt, (2) lengthening bearing pin, (3) pressure ring, (4) roller chain, (5) annulus.
Accompanying drawing 2 is another model structural representation of the present utility model.
Solution of the present utility model is: this mechanism is driving wheel with the sprocket wheel, the meshing roller sprocket wheel is a follower in addition, its critical component is a meshing roller chain follower, the concrete making is the outer side surface that standard roller chain (4) is installed in the annulus (5) that has boss, with pressure ring (3) and clamping bolt (1) roller chain (4) is fixed, lengthening bearing pin (2) is in order to replacing roller chain chain internode original pin shaft, and insert respectively in the pin shaft hole on annulus boss and the pressure ring at its two ends.More than used clamping bolt (1) and the lengthening bearing pin generally respectively be 8.Adopt said method can make outer gearing roller chain wheel transmission device, this transmission device can be used with standard sprocket and constitute the outer gearing transmission.Accompanying drawing 2 is another model schematic representation of the present utility model, and the difference of annulus (5) is that its center is processed with axis hole among it and Fig. 1, is used for this transmission device and is installed in the occasion that stationary axle rotates, and its effect is same as shown in Figure 1 with principle.
The utility model has the advantages that: (1) this device belongs to engaged transmission, so average ratios is more accurate, The transmission efficiency height; (2) because chain has flexiblely, can slow down to a certain extent impact; (3) can To realize easily the big speed ratio transmission, this is to have good processability, transmission owing to form member Than increasing, only need to increase the roller chain joint number, increase annulus and pressure ring diameter and get final product, do not have processing side The problem of face. And gearratio is more big, and the driven pulley size is more big, and this device transmission effect is more good; (4) In light weight, whole transmission device, especially driven member weight obviously is lighter than other transmission mechanisms; (5) worker Do reliably, the life-span is long, and this device main failure forms is that roller chain skids, but because roller chain Adopt pressure ring and bearing pin to fix, pressure ring compresses with bolt, and enough thrusts can be provided, to prevent Roller chain skids. Be higher than straight-tooth gear and common chain transmission its service life; (6) because annulus processing letter Easily, the size Selection scope is big, can design in the annulus inboard as required the position that transmission part is installed Put, driven member can directly use as transmission mechanism; (7) installation form is flexible, and driven pulley both can be installed At the fixed axis upper driving, also can with annulus boss cylindrical as the plane of rotating, make it in fixing The heart rotates. This device is easy to process, and installation form is flexible, and average ratios is accurate, can be widely Be applied to middle or small load, the occasion of big speed ratio.
Claims (2)
1, a kind of outer gearing roller chain wheel transmission device is characterized in that it is that the standard roller chain is installed in an annulus outer side surface that has a boss.
2, according to the said transmission device of claim 1, it is characterized in that roller chain being fixed with pressure ring and clamping bolt, the lengthening bearing pin replaces roller chain chain internode original pin shaft, and insert respectively in the pin-and-hole on annulus boss and the pressure ring at its two ends.
