Λ| Don't describe the further improved shifting effect. ^ Also, the two-stage shifting effect can be achieved. However, due to the straight-forward use of the two-speed shift, the slave has no deceleration, so it is not suitable for electric motors. It is necessary to start the torsion force, and the clothes are placed. Therefore, there is a modified M, a torque device and a two-speed shifting device. [New content] The existing shifting device is more unsuitable for this, and it is used for electric motors with less torque. The main purpose of the textbook is to add a second star to the structure. The two-stage shifting configuration of the torque output is available for use with 4 M339386. In order to achieve the above object, the present invention provides a spindle drive shifting device, comprising: a housing, the housing is provided with a body, and the circular tube of the system is disposed with an oblique guiding hole around the front portion. A bearing block and a rear bearing are respectively fixed on the front and the rear end, a front block is formed behind the bearing seat, a front bearing is embedded on the inner side, and a sun tooth ring is fixed on the rear side of the body; a transmission shaft, a 5 hp transmission shaft is disposed on the front bearing, and a rear-end portion of the transmission shaft forms a - a star * wheel seat, and the three star gears are combined with the rotatable opening state around the star gear carrier a second planetary gear set, which is provided with a second planetary gear seat corresponding to the rear of the transmission shaft, a connecting gear is protruded in front of the second planetary gear seat, and a straight axis is extended forward in the center of the connecting gear. Engaging the three axes of the star gears with the straight shaft, and rotating, in a rotatable manner, three second star gears respectively meshing with the sun gear ring; a connecting shaft, the connecting shaft is disposed For the rear bearing, the link The rear end of the shaft •• forms a coupling hole and the front end is meshed between the three second star gears; the middle speed sleeve of the document is 'sliding sleeve around the transmission shaft, 忒' The inner peripheral wall cooperates with the star gears and the connecting gears to be y into sun teeth, and the sun teeth mesh with the star gears. In the shifting, the sleeves are formed into the rear blocks of the front block, and the shifting sleeve is set in the shifting sleeve. Surrounding the formation-slide, a push block is slidably embedded in the slide; and a shifting ring is disposed around the body to decelerate. A push rod that passes through the guide hole is coupled between the black push blocks. 5 M339386 rudder, the body is divided into a front section and a rear section having a larger diameter than the front section, and a middle bearing is embedded in the front end of the inner peripheral wall of the rear section of the raft body, and the sun gear ring is shackled to the inner peripheral wall of the rear section of the body, and An annular step portion is recessed adjacent to a front end edge of the circumferential surface of the first planetary gear carrier adjacent to the middle bearing, and the step portion is embedded in the middle bearing. The front end of the connecting shaft of the rim is extended from the middle of the rear end of the second planetary gear carrier and meshed between the three second planetary gears, between the front end of the connecting shaft and the middle of the rear end of the first traveling gear carrier A positioning bearing is embedded. This creation provides a tool combination with the front end of the drive shaft and a drive source connection with a motor shaft jack that connects the rear of the shaft. When in use, the power source is transmitted through: the cooperation between the two-star gear set and the sun gear ring, and the cooperation of the Ui wheel and the sun tooth at the rear end of the drive shaft to achieve two-stage deceleration, the speed is sequentially reduced and forward It is transmitted to the drive shaft, whereby it is decelerated and then output by the combined tool. When the creation needs to increase the output speed, the shifting ring is rotated to move the shifting sleeve backwards. 'The sun teeth simultaneously mesh with the star gear and the connecting gear'. At this time, the second star gear seat, the shifting middle sleeve and the transmission shaft will become one. The rotating structure causes the power source to rotate the tool only through the deceleration of the second star gear set and the sun gear ring. β This creation uses the shifting ring to rotate the shifting sleeve to move forward and backward, thereby providing a two-stage adjustment design for the user's speed change. Due to the speed adjustment of the two sections, the speed can be used to improve the output: The torque adjustment device with the torque and the user's torque output is suitable for use in devices with low torque such as electric motors. 6 M339386 [Embodiment] This is a spindle transmission shifting device.

The drive shaft (the rear end is located on the body (1 1) On the rear side of the front section, a disc-shaped star gear S (2l) is formed at the rear end of the transmission shaft (2), and three equal-shaped star gears are combined in a rotatable manner around the star wheel (2 1 ). 22), the outer side of each raspberry and the gear (2 2 ) protrudes from the outer surface of the planetary gear seat (21). Take the second star gear set (3〇), the second star gear set (3 7 M339386 has a second star gear seat (3 1), the second star gear seat (3 workers), the circumferential edge of the rim is recessed to form a ring-shaped class (3 1 1 ), the first - star gear The seat (3 i ) is disposed on the front side of the rear portion of the body (丄1) and is embedded in the middle bearing (i 5 ) by the step portion (3 1 1 ), and protrudes in front of the second star gear carrier (31). The gear (32), the size of the surrounding of the gentleman's tooth (3 2 ) corresponds to the outer edge of the three planetary gears (2 2 ). The main shaft (3 3 ) extends forward from the center of the connecting gear (3 2 ). , around the straight axis (3 3 ) a transmission tooth (3 3 1 ) is meshed between the three planetary gears (2 2 ) by the transmission teeth (3 3 1 ), and is coupled to the third planetary gear carrier (3 1 ) in a rotatable manner The second tour star #34 (34) of the interval, the three star gears (34) 0 and 22 sides mesh with the inner side of the sun gear ring (17). A connecting shaft (40), connecting shaft (4〇) ) is threaded through the rear bearing (16), and a coupling hole (4 1 ) for providing a motor shaft coupling is formed at the rear end of the connecting shaft (4 〇), and the front end of the connecting shaft (4 〇) is made of the second gear ( 3 1) The middle of the rear end projects into and engages between the three second revolving gears (34) between the front end of the connecting shaft (4〇) and the middle of the rear end of the second revolving gear base (3 1 ) A positioning bearing (4-speed shifting sleeve (5 0) is embedded, and the shifting middle sleeve (5 〇) is annular and slidably arranged around the transmission shaft (2 〇), and the shifting sleeve (5 0) ) is located in the front section of the body (1 1 ) and the rear end of the inner peripheral wall cooperates with the planetary gears (22) and the connecting gears (32) to form a sun: (51), and the sun teeth (51) mesh with the three stars Around the wheel (22), the front end of the shifting sleeve (5〇) is fitted with the front block (1 8 M339386 forms the rear card (5 2) which is mutually engaged, and the subsequent block (52) is stuck in the front card The block (1 3 1 ) causes the shifting sleeve (50) to not rotate, forming a ring-shaped slide (5 3 ) around the shifting sleeve (5 Q ), and inserting a slide on the slide (5 3 ) q Push block (5 $ ), push block (5 4 ) is a half-shaped ring body. a variable arresting ring (60), the shifting ring (6 〇) is a ring body and is rotatably disposed around the front section (1 1 1 ) of the body (1 1 ) and is quickly β (β 0 ) The inner peripheral wall of the front end portion is recessed to form a concave portion (6 1 ), and a corresponding push hole (6 2 ) is formed on the inner wall in the front and rear direction, and the push rod groove (6 2 ) and the push block are 5 4) Insert a push rod (6 3 ) between the push rod (6 3 ) through the guide hole (1 1 1 ) of the body (worker), at the rear end edge of the front cover (work 2) A spring (6 4 ) is disposed between the recesses (6 1 ) of the shifting % (60). ^When this creation is used, please refer to the third to fifth figures, which are connected with the front end of the transmission vehicle (2 〇), and the coupling hole (4 1 ) of the rear connection shaft (4 〇) is combined with a driving source such as an electric motor.
