Summary of the invention
For the deficiencies in the prior art, the utility model provides roller chain coupling, include the first sprocket wheel, with the second sprocket wheel of described first sprocket engagement, be formed in the first protective housing of described first sprocket wheel and described second sprocket wheel outside, the second protective housing be connected with described first protective housing, be positioned at the collar on described first sprocket wheel and described second sprocket wheel side, described first protective housing both ends of the surface stretch out formation first flange, described first flange is formed with keyway on several, described second protective housing both ends of the surface stretch out formation second flange, described second flange is formed with several lower keyways, be connected by flat key between described upper keyway with described lower keyway, described first flange and described second flange are formed with bolt hole, the below of described first sprocket wheel and described second sprocket wheel is formed with elastic device.
Further, damping coating is scribbled in described upper keyway.
Further, damping coating is scribbled in described lower keyway.
Further, described elastic device comprises clockwork spring and elastic ring, and the inner side of described elastic ring is connected with described clockwork spring, and described first sprocket wheel in outside of described elastic ring and the below of described second sprocket wheel connect.
Further, the inner side of described elastic ring is formed with the block limiting described clockwork spring the sphere of activities.
Further, described first protective housing is formed with direct current through hole.
Further, described direct current through hole outside is connected to pump nozzle, and described pump nozzle indentation, there is formed renovates.
The beneficial effects of the utility model are: by the dual connection between two protective housings, make protective housing more firm, carry out vibration reduction and cushioning by elastic device to sprocket wheel, reduce the wearing and tearing of sprocket wheel, improve the working life of coupling, and this coupler structure is reasonable, convenient disassembly.
Accompanying drawing explanation
The perspective view of the roller chain coupling that Fig. 1 provides for the utility model embodiment.
In figure, 101 is the first sprocket wheel, and 102 is the second sprocket wheel, and 1021 is clockwork spring, and 1022 is elastic ring, 103 is collar, and 104 is the first protective housing, and 1041 is upper keyway, and 1042 is the first flange, 105 is the second protective housing, and 1051 is lower keyway, and 1052 is the second flange, and 1053 is direct current through hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As Fig. 1 to shown in, the preferred embodiment that the utility model provides.
Roller chain coupling, can be used in the axle system transmission that may be used for the machineries such as weaving, agricultural machinery, lifting transport, engineering, mine, light industry, chemical industry.
Roller chain coupling, include the first sprocket wheel 101, second sprocket wheel 102, first protective housing 104, second protective housing 105, collar 103, wherein, second sprocket wheel 102 engages with the first sprocket wheel 101, first protective housing 104 is formed in the first sprocket wheel 101 and the second sprocket wheel 102 is outside, second protective housing 105 is connected with the first protective housing 104, collar 103 is positioned at the first sprocket wheel 101 and the second sprocket wheel 102 side, first protective housing 104 both ends of the surface stretch out formation first flange 1042, first flange 1042 is formed with keyway 1041 on several, second protective housing 105 both ends of the surface stretch out formation second flange 1052, second flange is formed with several lower keyways 1051, be connected by flat key between upper keyway 1041 with described lower keyway 1051, first flange 1042 and the second flange 1052 are formed with bolt hole, the below of the first sprocket wheel 101 and the second sprocket wheel 102 is formed with elastic device.
By the dual connection between two protective housings, make protective housing more firm, by elastic device, vibration reduction and cushioning is carried out to sprocket wheel, reduce the wearing and tearing of sprocket wheel, improve the working life of coupling, and this coupler structure is reasonable, convenient disassembly.
Particularly, in upper keyway 1041, scribble damping coating, in lower keyway 1051, scribble damping coating, when diaxon operates, will be cut down by damping coating the impact that coupling produces, and avoid the wearing and tearing to sprocket wheel.
Elastic device comprises clockwork spring 1021 and elastic ring 1022, the inner side of elastic ring 1022 is connected with clockwork spring 1021, the outside of elastic ring 1022 is connected with the below of the first sprocket wheel 101 and the second sprocket wheel 102, elastic ring 1022 withstands shocks, due to the vibration that the resiliently deformable of elastic ring 1022 and dodging under clockwork spring 1021 acts on are reduced impact and produced, improve the working life of coupling.
The inner side of elastic ring 1022 is formed with the block of restriction clockwork spring 1021 the sphere of activities, is conducive to like this preventing clockwork spring 1021 from misplacing.
Particularly, the first protective housing 104 is formed with direct current through hole 1053, direct current through hole 1053 outside is connected to pump nozzle, and pump nozzle indentation, there is formed renovates, and utilizes flip structure, and can better keep can not be contaminated when lubricating.
What describe in above-described embodiment and specification just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
