The present invention relates to a driving structure for upward-opening abrasive cloth rollers, and more particularly to a driving structure combined with the roller.
Currently, the conventional machine structure of the abrasive cloth roller mainly comprises a roller with an abrasive cloth outside, an external motor with connection of a belt and an idler structure for transmitting power to the roller to rotate. The above structure actually has the following disadvantages:
(1) The motor, the idler, and the belt drive the roller together. However, the motor is an external structure because of requiring a large space, so the entire abrasive cloth roller machine has large dimensions.
(2) To transmit power through the belt transmission, it is required to pay attention to the belt tension and make adjustment to ensure that the belt and each transmission wheel have appropriate fit. However, the disadvantage of the belt drive is that the belt may slip during high-speed operation or need to be replaced. And, it is more likely result in breakage during operation due to negligence of inspection, which causes high elimination rate and high maintenance costs.
Therefore, it is desirable to provide a driving structure for upward-opening abrasive cloth rollers to mitigate and/or obviate the aforementioned problems.
An objective of present invention is to provide an adjustment structure of upward-opening abrasive cloth rollers, which is capable of improving the above-mention problems.
In order to achieve the above mentioned objective, A driving structure for upward-opening abrasive cloth roller mainly consists a motor mounted in the roller. The driving structure includes: a roller, a first side member, a second side member, a motor with an outer ring gear integrated into a rotating structure; and a motor, a linking shaft bearing, a connecting member, a fixed member and a second bearing integrated with the roller as a stationary structure. The power of the motor is transmitted to the linking shaft, the sun gear, the planet gear through the rotating shaft of the motor, and finally transmitted to the outer ring gear, so that the roller can be rotated.
Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
First, please refer to
In addition, the fixed member 23 has more than one passive shaft 230 and more than one planet gear 231, as shown in
Furthermore, the linking shaft 220 and the sun gear 221 can be individual objects, the sun gear 221 can be an independent abject than the linking shaft 220. Also, the passive shaft 230 and the passive gear 231 can be integrally formed, the second side member 12 and the outer ring gear 120 are individual objects, and the outer ring gear 120 may be an independent object mounted on the second side member 12.
According to the above structure, the following functions and advantages can be obtained:
(1) The motor 20 and the entire transmission structure are hidden inside the roller 10, which can greatly reduce the volume of the machine.
(2) By utilizing planetary gear system, the transmission efficiency is higher, the service life is longer, the weariness is less, and the maintenance cost is lower.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
