Description

The high-speed synchronous belt driver

[technical field]

The utility model relates to a kind of mechanical transmission mechanism, particularly a kind of high-speed synchronous belt driver.

[background technique]

Traditional transmission device, be generally chain-driven or band transmission, wherein chain-driven produces inhomogeneous fluctuating owing to polygon effect makes chain on sprocket wheel, causes the asynchronous of principal and subordinate wheel, thereby, influenced the precision of transmission, in addition, because chain-driven can not apply pre-tensioning, therefore, the obvious slack list of chain on one side in the transmission, the serious step-out phenomenon when causing the chain-driven clockwise and anticlockwise.The band transmission is owing to exist inevitable elasticity sliding motion in transmission process, therefore, this kind of drive also can not realize the run-in synchronism of principal and subordinate wheel.

In view of above problem, in fact be necessary to provide a kind of high-speed synchronous interband that can solve the problems of the technologies described above transmission device of having a rest.

[model utility content]

The utility model provides a kind of high-speed synchronous belt driver, can realize the synchronous and simple in structure of principal and subordinate wheel.

The technological scheme that the utility model adopted is: a kind of high-speed synchronous belt driver, comprise the speed reducer that is fixed on the frame, the cam indexing mechanism, the coupling that connects speed reducer and cam indexing mechanism, the a pair of dunnage of fixedlying connected with the cam indexing mechanism, place between a pair of dunnage and the station that is connected with a pair of dunnage, driving wheel that is connected with station and follower, and with the engagement of driving wheel and follower and drive the synchronous band that station moves, wherein, the station bottom is extended with extension bar, in extension bar and the dunnage, one is provided with rolling bearing, and another is provided with guide groove.

As preferred embodiment of the present utility model, described dunnage is the one plate construction;

As preferred embodiment of the present utility model, the extension bar on the described station extends to synchronous band and fixedlys connected with being with synchronously.

The utility model high-speed synchronous belt driver has the following advantages at least: because in the extension bar and dunnage that stretch out the station bottom, one is provided with rolling bearing, another is provided with guide groove, therefore, in the process that synchronous band is transmitting, rolling bearing rolls in guide groove, so, prevent owing to the undue compressing of station and top product thereof synchronously band produces vibration and is out of shape, and then influence transmission accuracy.

Fig. 1 is the plan view of the utility model high-speed synchronous belt driver;

Fig. 2 is the plan view of the utility model high-speed synchronous belt driver.

The label among the figure and the corresponding relation of element are as follows:

The 1-speed reducer, the 2-coupling, 3-cam indexing mechanism, the 4-dunnage, the 5-station, the 6-driving wheel, 7-is with synchronously, the 8-follower.

[embodiment]

See also Figure 1 and Figure 2, the utility model high-speed synchronous belt driver comprises rack-mounted speed reducer 1, cam indexing mechanism 3, connects the coupling 2 of speed reducer 1 and cam indexing mechanism 3, with the fixedly connected a pair of dunnage 4 of cam indexing mechanism 3, place between a pair of dunnage 4 and the station 5 that is connected with dunnage 4, be fixed on driving wheel 6 and follower 8 on the dunnage 4, and be with 7 synchronously with driving wheel 6 and follower 8 rollings are connected.

Dunnage 4 in the present embodiment, is the plate construction of one, certainly, in other embodiments, also can be the form of integral material upper mounting rail; Being with 7 synchronously, is tooth form synchronous belt in the present embodiment.

Station 5 bottoms are extended with extension bar, this extension bar extend to be with synchronously 7 and be with 7 to fixedly connected synchronously, so, when being with 7 to move synchronously, station 5 also is moved, and moves with the product on this feed station 5; In addition, the extension bar of station 5 also is equipped with needle bearing, corresponding therewith, dunnage 4 is provided with guide groove, is with 7 synchronously when mobile, the needle bearing of station 5 rolls in guide groove, bear the pressure of station 5 and top product thereof whereby, thereby, prevent that station and the top undue compressing of product thereof be with synchronously, thereby produce vibration and distortion, and then influence delivery precision.

The above only is a kind of mode of execution of the present utility model, it or not whole or unique mode of execution, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
