[0003] First, if the diameter of the synchronous wheel is very large, the diameter of the required synchronous belt must also be very large. At this time, it is extremely difficult to obtain a suitable synchronous belt, and even if a suitable synchronous belt can be found, its price is also very expensive

Second, in the field of astronomy, due to the large area of the synchronous belt w...

Example Embodiment

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of the invention is not limited by the specific embodiments.

[0019] Unless otherwise clear, otherwise, in the entire specification and claims, the term "comprising" or "including" or "comprising" or the like will be understood to include the components or components of the present, and Other components or other components are not excluded.

[0020] Such as figure 2 As shown, an embodiment of the present invention provides a synchronous belt transmission mechanism including a first housing 10, a second synchronous wheel 20, a ring synchronous tape 30, and a tensioning wheel group 40. The tensioning wheel group 40 is disposed between the first housing 10 and the second synchronous wheel 20, and the ring synchronous belt 30 is set on the tensioning wheel set 40, and rod to the first homage 10 and the second synchronization wheel 20, respectively. connect.

[0021] The ring synchronous belt 30 is formed along the side of its radial direction (not shown), and a teeth are provided with an equal spacing on the surface of the tooth layer. The circumferential surface of the first housing 10 and the second synchronous wheel 20 is provided with a tooth with a tooth layer, a tooth spacing of the first homing wheel 10 and the second synchronous wheel 20 weeks, equal to the band tooth of the ring synchronous belt 30. Layer tooth spacing. The annular synchronous belt 30 has a side outer valve with a tooth layer, engaged with the first housing 10 and the second synchronous wheel 20, and the annular synchronous belt 30 is not in contact with the tensioning wheel group 40.

[0022] The first housing 10 and the second synchronizing wheel 20 have a relatively close first surface segment 10a and the second surface segment 20a, and the tape layer of the annular synchronous strip 30 engages the first surface segment 10a and the second surface segment 20a, respectively.

[0023] In an embodiment, the tensioning wheel group 40 includes three fixed tension wheels 41 and a tonable tension wheel 42. The annular synchronous belt is set in four tension wheels (41/42), forming a quadrigid structure, and the first housing 10 and the second synchronous wheel 20 each engaged on different sides of the four-bodies structure. The adjustable tension wheel 42 can be moved relative to the fixed tension wheel 41 to adjust the engaging pine duration between the annular synchronous belt 30 and the first housing 10 and the second synchronous wheel 20.

[0024] In a specific embodiment, the number of adjustable tension wheels 42 can also be two or more.

[0025] In a specific embodiment, the diameter of the first housing 10 is greater than the diameter of the second synchronous wheel 20. The first housing 10 and the second synchronous wheel 20 respectively engage the two edges of the four-bodies structure.

[0026] In a specific embodiment, the first housing 10 having a large diameter may not be a complete circular gear, and may be part of a complete circular gear.

[0027] In an embodiment, the present invention also provides a telescope angular adjustment mechanism including the above-described synchronous belt transmission mechanism.

[0028] Compared with the prior art, the synchronous belt transmission mechanism of the present invention is wrapped on the ring synchronous belt on the tensioning wheel, and the annular synchronization belt is provided with a tooth layer. And with the first synchronization wheel and the second synchronization wheel with a small contact surface, the ring synchronization belt is adjusted between the ring synchronous belt and the first and second synchronization wheels by one or more adjustable tensioners. Tight, thus realizing power transmission, reducing operation noise, and improving the tracking accuracy of telescope.

[0029] The foregoing description of the specific exemplary embodiments of the present invention is for purposes of illustration and illustration. These descriptions are not intended to define the present invention as the disclosed precise form, and it is clear that many changes and variations can be made according to the above teachings. An object of selecting and description of an exemplary embodiment is to explain a particular principle of the present invention and its practical applications thereof, thereby enabling various exemplary embodiments of the invention and various different exemplary embodiments of the present invention. Select and change. The scope of the invention is intended to be limited by the claims and equivalents thereof.
