Embodiment Construction
[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0009] exist figure 1 Among them, the present invention is a cylindrical roller bearing with an integrated planetary gear reduction device, which is mainly composed of an input shaft 1, an inner ring 2, a rolling element 3, a cage 4, an outer ring 5, an outer ring sun gear 6, 7. The input shaft sun gear 8, the planet carrier 9, and the screw 10 are composed. Its internal structure is as follows: the inner ring 2 and the outer ring 5 of the two bearings have small grooves respectively, and they cooperate to form a small cavity, and the rolling elements 3 and the cage 4 are installed inside; the outer rings of the two bearings 5 The axial width is wider than the inner ring 2, and it has a stepped structure. The two bearing outer rings 5 are connected by screws 10 to form a cavity. One of the bearing outer rings 5 is equipped with a gear on ...

The invention relates to a cylindrical roller bearing of an integrated planetary gear speed reducing device. The device comprises an input shaft, inner rings, a rolling body, a retainer, outer rings, an outer ring sun gear, a planetary gear, an input shaft sun gear, a planetary carrier and a screw, wherein a small groove is formed in each of the inner ring and the outer ring of each of two bearings, and the small grooves are matched to form a small cavity in which the rolling body and the retainer are mounted; the axial width of the outer rings of the two bearings is larger than that of the inner rings, the outer rings of the two bearings are of stepped structures and are connected through the screw to form a chamber, and the inner wall of the chamber of the outer ring of one of the bearings is provided with a gear named as the outer ring sun gear; the input shaft is in interference fit with the inner ring of one of the bearings, and the end extending into the input shaft of the chamber is provided with a gear named as the input shaft sun gear; and the planetary gear is arranged between the two sun gears and is supported by the planetary carrier, and the planetary carrier is in interference fit with the inner ring of the other bearing and is also named as an output shaft.
Description
technical field [0001] The invention relates to a cylindrical roller bearing, in particular to a cylindrical roller bearing integrated with a planetary gear reduction device. Background technique [0002] The gear train reducer has the following characteristics: it can realize split transmission; it can obtain a larger transmission ratio; it can realize variable speed transmission; it can realize reversing transmission; The deceleration part of the system is widely used, especially in private server motor reducers, most of which are decelerated by planetary gear reducers. However, adding an independent deceleration device inside the machine will undoubtedly increase the cost of the machine, complicate the internal structure of the machine, and cause the installation to remain unchanged. If there is a set of bearing device with an integrated deceleration system, without changing the original mechanical structure of the machine or adding an external speed regulating device, o...
