Description
Technical Field
The present invention relates to a transmission structure using a rope as a power transmission medium.
Background
There are many types of conventional power transmission mechanisms, such as: belt drive, gear drive, worm gear drive, and rope drive.
The rope transmission consists of a pulley with a groove and a rope serving as a flexible traction part, and has the advantages of simple rope transmission structure, low manufacturing cost, small noise, small inertia, stable transmission, high tensile strength, long-distance transmission and the like, so that the rope transmission is widely applied to the fields of aviation, military, medical treatment and scientific research.
The conventional rope transmission pulley must have corresponding rope grooves, but when the pulley is used for two vertically adjacent pulleys (as shown in fig. 1 and 2), the pulley is required to have the rope grooves, and the centers of the rope grooves of the two pulleys are coincident to reduce motion wear, so that the two pulleys can have interference.
Disclosure of Invention
The invention aims to provide a combination structure of a grooved pulley, which solves the interference problem in the prior art.
In order to achieve the above purpose, the invention adopts the following technical scheme:
the utility model provides a combination structure of trough of belt pulley, includes first pulley and second pulley, its characterized in that:
the first pulley and the second pulley are connected in an inclined way, rope grooves with the same diameter are arranged on the first pulley and the second pulley along the rims, and circle centers of the two rope grooves at the connecting positions are coincident;
the first pulley and the second pulley are respectively provided with a circle of bevel teeth on the radial inner side of the rope groove, and the two circles of bevel teeth are meshed at the joint position.
The combination structure of the grooved pulley comprises the following components: the first pulley and the second pulley are respectively arranged on two adjacent shafts of a cross shaft.
The combination structure of the grooved pulley comprises the following components: the first pulley and the second pulley are vertically connected.

Detailed Description
As shown in fig. 3-7, the present invention provides a combination structure of grooved pulleys, which has a first pulley 1 and a second pulley 5 that are connected in an inclined manner, in this embodiment, the first pulley 1 and the second pulley 5 are respectively mounted on two adjacent shafts of a cross shaft 4 through bearings 2 to form a vertical connection;
as shown in fig. 4 and 5, rope grooves 6 with the same diameter are arranged on the first pulley 1 and the second pulley 5 along the rims, and the centers of the two rope grooves 6 are overlapped at the connecting position so as to improve the friction force of the rope grooves 6 to the rope body 3 at the connecting position;
as shown in fig. 4-7, in order to avoid interference, the first pulley 1 and the second pulley 5 are respectively provided with a circle of bevel teeth 7 on the radial inner side (i.e. opposite side) of the rope groove 6, and the two circles of bevel teeth 7 are meshed at the connection position, so that interference is avoided, and slipping of the first pulley 1 and the second pulley 5 in the transmission process is prevented;
when in use, as shown in figure 3, the rope body 3 winds a half circle on the first pulley 1, and winds a half circle on the second pulley 5 after passing through the connection position; when the rope body 3 is pulled, the first pulley 1 and the second pulley 5 can be rotated synchronously by friction force and gear engagement force.
Of course, the combination structure of the grooved pulley provided by the invention is not limited to be used in the vertical connection, and when the mutual inclination angle of the first pulley 1 and the second pulley 5 is changed, the effects of avoiding interference and synchronously driving can be achieved by adjusting the central angle of the rope groove 6 and the taper of the bevel gear 7.
The above description is illustrative of the invention and is not to be construed as limiting, and it will be understood by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
