Abstract
The utility model relates to a transmission spare part. The common gear is generally driven to rotate by a flat key, and the transmission and the meshing of the gear are rigid, so that vibration and noise are inevitably generated. In order to solve the problems, the utility model provides a flexible transmission gear, which comprises a gear body and a nylon pin; a plurality of semicircular grooves are uniformly distributed on the circumference of an inner hole of the tooth body; a semicircular groove on an inner hole of the tooth body penetrates through the tooth body; the number of the nylon pins is the same as that of the semicircular grooves uniformly distributed on the circumference of the inner hole of the tooth body, and the nylon pins are in interference fit with the semicircular grooves on the inner hole of the tooth body. The utility model has the advantages that: the rigid transmission and the meshing of the variable gears are flexible transmission and meshing, and vibration and noise generated during the transmission and the meshing of the gears are eliminated fundamentally.
Description
Technical Field
The utility model relates to a transmission spare part, especially a flexible drive gear of elimination transmission vibration and noise.
Background
The common gear is generally driven to rotate by a flat key, and the transmission and the meshing of the gear are rigid, so that vibration and noise are inevitably generated.
Disclosure of Invention
In order to solve the problem, the utility model provides a flexible transmission gear.
The utility model adopts the technical proposal that:
the flexible transmission gear comprises a gear body and a nylon pin; a plurality of semicircular grooves are uniformly distributed on the circumference of an inner hole of the tooth body; a semicircular groove on an inner hole of the tooth body penetrates through the tooth body; the number of the nylon pins is the same as that of the semicircular grooves uniformly distributed on the circumference of the inner hole of the tooth body, and the nylon pins are in interference fit with the semicircular grooves on the inner hole of the tooth body.
The utility model has the advantages that: the rigid transmission and the meshing of the variable gears are flexible transmission and meshing, and vibration and noise generated during the transmission and the meshing of the gears are eliminated fundamentally.
Drawings
The following is further illustrated in connection with the figures of the present invention:
fig. 1 is a front view of the structure of the present invention.
Fig. 2 is a left side view of the structure of the present invention.
In the figure, 1 is a tooth body, and 2 is a nylon pin.
Detailed Description
The flexible transmission gear comprises a gear body 1 and a nylon pin 2; a plurality of semicircular grooves are uniformly distributed on the circumference of an inner hole of the tooth body 1; a semicircular groove on an inner hole of the tooth body 1 penetrates through the tooth body 1; the number of the nylon pins 2 is the same as that of the semicircular grooves uniformly distributed on the circumference of the inner hole of the tooth body 1, and the nylon pins are in interference fit with the semicircular grooves on the inner hole of the tooth body 1.
When the flexible transmission gear is installed, the tooth body 1 is sleeved on a transmission shaft (not shown in the figure), the transmission shaft corresponds to the tooth body 1, and a plurality of semicircular grooves are uniformly distributed on the outer cylindrical surface; the gear body 1 or the transmission shaft is rotated, so that a semicircular groove in the circumference of the inner hole of the gear body 1 is aligned with a semicircular groove in the outer cylindrical surface of the transmission shaft, then the nylon pins 2 are knocked into circular holes formed by the semicircular groove in the circumference of the inner hole of the gear body 1 and the semicircular groove in the outer cylindrical surface of the transmission shaft, and the nylon pins 2 are in interference fit with the nylon pins.
