Abstract
The utility model relates to a strengthened internal link plate, in particular to an internal link plate used for a roller chain transmission device. An annular flange is arranged at the periphery edge of an axle hole of the internal link plate. By the aid of the flange structure, area of the radial cross section of the axle hole of the internal link plate is expanded, the defective of weak tensile strength of a general internal link plate is overcome, and tensile strength of the internal link plate is increased, so that tensile strength of a chain is strengthened and service life of the chain is prolonged.
Description
Technical field
A kind of reinforced inner plate is specially a kind of inner plate that is used for roller chain transmission device.
Background technique
Existing roller chain is made up of inner plate, bearing housing, roller, bearing pin and outer plate, and inner plate, bearing housing and roller are formed inner link, and outer plate and bearing pin are formed outer link.Roller chain is in running, and inner plate bears the pulling load effect of chain, belongs to weak link, and the ability of inner plate bearing load concerns the ability of whole chain bearing load.Common inner plate all adopts the board-type structure, its tensile strength and to bear load intensity lower, and fragile inefficacy causes shortening working life of roller chain.
Summary of the invention
Shortcomings such as the utility model provides a kind of reinforced inner plate, has solved original inner plate tensile strength deficiency, and it is lower to bear load carrying capacity, and working life is short.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of reinforced inner plate is complementary with the roller of chain, and this inner plate is made up of chain plate body and flange, there is axis hole at the two ends of chain plate body, and flange is circular, are positioned at the axis hole periphery of inner plate one side, the flange internal diameter is identical with shaft hole diameter, and its external diameter is less than roller outer diameter.
This reinforced inner plate has increased flanged structure, makes the tensile strength of inner plate and bear load carrying capacity all to be improved, and has prolonged the working life of roller chain.
Accompanying drawing is described
Fig. 1 is the structural representation of reinforced inner plate;
Among the figure, 1-chain plate body, 2-flange, 3-axis hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed specific description.
The structure of this reinforced inner plate is made up of chain plate body 1 and flange 2 as shown in Figure 1, and the two ends of chain plate body 1 are respectively equipped with axis hole 3, flange 2 is circular, be positioned at axis hole 3 peripheries of chain plate body 1 one sides, flange 2 internal diameters are identical with axis hole 3 internal diameters, and its external diameter is less than roller outer diameter.
This inner plate and bearing housing and roller coupling, three's composition inner link that combines.The one side of inner plate flanged pin 2 is positioned at the inboard of inner link, because the internal diameter of flange 2 is identical with axis hole 3 diameters, so bearing housing can be packed in the axis hole by normal procedure.Under the prerequisite that guarantees the inner link inner width, suitably shorten the roller width, stay certain installing space to flange, and since the external diameter of flange 2 less than the external diameter of roller, so chain can not have influence on the normal operation of roller fully in running flange 2.
Chain is in running, suffered pulling load active force mainly concentrates on inner plate and the bearing pin, and the main positions of inner plate institute bearing load is on the radial cross-section of axis hole 3 peripheries, as shown in Figure 1, it is the position of area minimum in the chain overall structure herein, the inefficacy that easily is damaged, so the area of this radial cross-section directly has influence on the tensile strength of chain.In the utility model, at the periphery of axis hole 3, set up flange 2, the radial cross-section area of axis hole 3 peripheries is increased, thereby improved the tensile strength of inner plate, further improved the tensile strength of chain integral body, prolong the working life of chain.
Claims (3)
1. reinforced inner plate comprises the chain plate body that the roller with chain is complementary at least, and it is characterized in that: inner plate is made up of chain plate body and flange, and the two ends of chain plate body are respectively equipped with axis hole, and flange is circular, is positioned at the axis hole periphery of chain plate body one side.
2. a kind of reinforced inner plate according to claim 1, its feature with: flange internal diameter and shaft hole diameter are identical.
3. a kind of reinforced inner plate according to claim 1, its feature with: flange outside diameter is less than roller outer diameter.
