The wire bearing 42 is positioned at the second level 22 of the main shaft 2G, and the main bearing 42 abuts the brake element 3〇. The second oil seal is positioned at the third _ 23 ' of the main shaft, the _ miscellaneous bearing 44 is designed to be tapered, and the auxiliary roller bearing 44 g and the second oil seal 43 are positioned at the fourth level ^; The torque motor 5〇 is made up of a combination of a mover holder, a dicing seat W, a mover oil seal 52, ', a mover 53, a motor stator 54 and a motor cooling seat 55. The fixing seat 51 abuts against the main bearing 42 of the bearing assembly 4 () and the two = 52 and the rider 53 are fixed to the outside of the mover mount 51, and the horse = The motor cooling seat 55 is positioned inside and the motor stator 54 is sleeved outside the horse, and the body 60 includes a shell member οι, a t .... cutting edge W and a back cover oil seal 63, = after solidification Cover 62彳嶋, body 6G 1 and brake component 3 该 该 本体 该 该 该 本体 本体 之间 之间 之间 之间 之间 之间 之间 之间 之间 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂 润滑油 润滑油 润滑油 润滑油" (4) The road B includes a first oil passage 64, a first oil chamber prevention, and a grease nozzle 1337440. An oil to 65 is a ring-shaped open space correspondingly surrounding the outer side of the main bearing 42, and the first oil passage 64 is connected. An opening 641 is formed through the first oil chamber 65, and a rear cover 62 of the other body 60 is positioned on the opening 641 to be positioned on the first oil seal 43 and the auxiliary roller of the wire bearing assembly 4 Outside the column bearing 44, the rear cover 62 is provided on the inner side of the rear cover 62, and the cover member 61 is located at the outermost side to accommodate the aforementioned components, and the case member 61 is fixed to the motor cooling seat 55 of the direct drive torque motor 50; The position detecting component 70' is turned over on the back cover 62 of the body 6Q and the position detecting component 70 senses the change of the rotational position of the spindle 2〇; 80, the two locks on the external thread segment 25 of the end of the 2G, and the adjusting nut 80 is positioned in the cover oil seal 63 of the body 60, and the adjusting screw _ feeds the auxiliary roller bearing that presses the bearing assembly 4〇 44; The foregoing structure and group rib capacity are the key technologies of the present creation, and further contain the relationship position of the related elements of the present invention and an overview thereof. Referring to each of the above, the above-described technology of the present invention has clearly revealed the structure, and the following description of the operation of the present invention: Since the end of the main shaft 20 of the present invention is provided with a plurality of columnar second oil chambers 26, each of the oil chambers 26, the outer opening is provided with a cover 26 and the second oil chamber 26 is connected to the first/white layer 21, and the second oil chamber 26 cooperates with the second oil filling passage of the brake element 3〇 to form a second lubricating oil. Road A' This second lubricating oil passage A can directly inject oil into the second oil filling passage 32. Since the brake element 30 does not rotate, the second oil filling passage 32 9 1337440 can directly fall (10) the second of the main shaft (9). In the oil chamber 且 and stored in the first oil to 26, the running between the main shaft 20 and the brake unit 3G is performed at any time. The effect of the second lubricating oil passage 8 is effectively achieved. (7) In addition, after the first lake oil passage B of the body 60 is oiled from the grease nozzle 66, the oil_ reaches the first oil chamber 65 from the first oil passage 64, and the first oil chamber 65 is wound around the main bearing. 42 outside the ring-shaped open space, so the oil will flow from the top to the bottom of the main bearing 42 and gradually penetrate into the main bearing with the operation, • Finally, the oil will penetrate into the inside of the main bearing 42 to fully Lubrication between the body print and the main bearing 42 also allows lubrication of the operation between the main shaft 2G and the main bearing 42. π According to the foregoing design, when the invention is to be used as a sister, the user only needs to use the first lubricating oil passage and the second lubricating oil passage to apply the oil filling, so that the oil can be fully filled. Lubrication of the charm bearing 42 and the spindle 2G: the use of a simple structure for spindle lubrication, and effectively reduce maintenance costs. In summary, this (four) can rely on the single structure for the main _ slip, and reduce maintenance costs, so this (four) "has the industry can be secret" should be undoubted, in addition, the forest case is revealed The Wei technology has the effect of being succinct and not negligent. Therefore, the "new reliance" and "progressiveness" of the present invention have been in compliance with the patent regulations, and the sharp law of the New Zealand patent, "Saki, 4, the investigation 1337440 [Simplified illustration of the drawings] Fig. 1 is an external view of an embodiment of the present invention.
