Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, and in particular relates to a speed reducer with horizontal multi-source drive and vertical output. Background Technology

[0002] RV reducers are precision transmission devices characterized by high transmission ratio, low output speed, and high load capacity.

[0025] The structure of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that these embodiments are descriptive and not limiting.

[0026] A reducer with horizontal multi-source drive and vertical output, please refer to [link / reference]. Figure 1-6The invention comprises: a support base 1, an RV reducer body 2, an upper connecting frame 3, a first 90° reversing rotation transmission assembly 4, a second 90° reversing rotation transmission assembly 5, a first gear 6, a second gear 15, a lower connecting frame 7; an outer cylinder 8, a first hand-cranked connecting shaft section 9, a linear bearing 10, a rigid coupling 11, a second hand-cranked connecting shaft section 12, a handle position sensor 13, a hand crank 14, a position sensor 16, a plum blossom coupling 17, a motor fixing flange 18, and a motor (not shown in the attached drawings).

[0027] The support base is used to support the RV reducer. It has a mounting platform at its upper end with a central hole. The support base has an internal mounting cavity and an external flange at its bottom for securing the support base.

[0028] The RV reducer body is vertically fixed to the support platform by screws, and the lower end of the RV reducer body is inserted and positioned in the center hole. The upper end of the RV reducer body is the output end.

[0029] The upper connecting frame is located at the upper part of the mounting cavity of the support base. The upper connecting frame is a disc-shaped support frame with screw through holes on the sides and a mounting hole in the center. The upper connecting frame is fixedly connected to the lower end of the RV reducer body by screws inserted into the screw through holes on the sides.

[0030] The lower connecting frame is located at the lower part of the mounting cavity of the support base.

[0031] Both the first 90° reversing rotary transmission assembly and the second 90° reversing rotary transmission assembly are reversing rotary assemblies with the input shaft arranged horizontally and the output shaft arranged vertically. The input shaft and the output shaft are meshed by bevel gears to realize 90° reversing transmission.

[0032] The first 90° reversing rotary transmission assembly is disposed within the mounting cavity of the support base. The first 90° reversing rotary transmission assembly is T-shaped. The upper end of the housing corresponding to the output shaft of the first 90° reversing rotary transmission assembly is positioned and fitted with the mounting hole of the upper connecting frame, and fixedly connected by screws. The upper end of the output shaft of the first 90° reversing rotary transmission assembly is coaxially fixedly connected to the input wheel of the RV reducer body. The lower end of the housing corresponding to the output shaft of the first 90° reversing rotary transmission assembly is fixedly connected to the lower connecting frame by screws. The second gear is fixedly mounted on the lower end of the output shaft of the first 90° reversing rotary transmission assembly, and the position sensor is coaxially fixed on the lower end of the output shaft of the first 90° reversing rotary transmission assembly to monitor the rotation angle of the reducer. A motor mounting flange is fixedly mounted on the outside of the support base corresponding to the input shaft position of the first 90° reversing rotary transmission assembly. The motor is horizontally fixedly mounted on the motor mounting flange, and the output shaft of the motor is coaxially fixedly connected to the end of the output shaft of the first 90° reversing rotary transmission assembly via a perforated coupling.

[0033] The second 90° reversing rotary transmission assembly is disposed within the mounting cavity of the support base, and the second 90° reversing rotary transmission assembly is L-shaped. The lower part of the housing corresponding to the output shaft of the second 90° reversing rotary transmission assembly is fixedly connected to the lower connecting frame by screws. The first gear is fixedly mounted on the lower end of the output shaft of the second 90° reversing rotary transmission assembly, and the first gear meshes with the second gear. The outer end of the input shaft of the second 90° reversing rotary transmission assembly is provided with a spline hole.

[0034] The end of the housing corresponding to the input shaft of the second 90° reversing rotary transmission assembly is fixedly connected to the inner end of the outer cylinder. The inner end of the first hand-cranked connecting shaft section is provided with an external spline. The outer end of the first hand-cranked connecting shaft section and the inner end of the second hand-cranked connecting shaft section are coaxially fixedly connected by a rigid coupling, forming a hand-cranked connecting shaft. The hand-cranked connecting shaft is coaxially disposed inside the outer cylinder. The hand-cranked connecting shaft and the outer cylinder are supported and movable relative to each other along the axial direction by multiple linear bearings. The external spline at the inner end of the first hand-cranked connecting shaft section is in a disengaging insertion fit with the spline hole of the input shaft of the second 90° reversing rotary transmission assembly. The outer end of the second hand-cranked connecting shaft section extends from the tail end of the outer cylinder and is fixedly connected to the hand crank handle. The hand-cranked connecting shaft adopts a two-section connection mechanism, allowing for a longer shaft length, which facilitates shaft processing and manufacturing.

[0035] The handle-in-position sensor is fixedly mounted on the outer cylinder wall near its tail end, with its trigger switch extending into the inner cavity of the outer cylinder. A switch contact plate 19 and a connecting shaft outward movement limiting plate 20 are fixed on the hand-cranked connecting shaft at positions inside and outside the trigger switch, respectively. The switch contact plate functions as follows: when the hand-cranked connecting shaft moves outward to the position where it contacts the trigger switch of the handle-in-position sensor, the aforementioned external spline head disengages from the spline hole, and the control system activates the motor, switching the reducer from manual to electric drive. The connecting shaft outward movement limiting plate contacts the inner surface of the outer cylinder bottom, controlling the outward movement of the hand-cranked connecting shaft and acting as a limiting post.

[0036] A cylinder support leg is provided at the lower part of the outer cylinder, and the lower end of the cylinder support leg contacts the ground to achieve horizontal and stable support for the outer cylinder.

[0037] The working principle of this multi-source drive reducer with vertical output is as follows:

[0038] This utility model's reducer achieves horizontal input from the motor and hand crank via a first 90° reversing rotary transmission assembly and a second 90° reversing rotary transmission assembly, with vertical output at the reducer's end. When manual input is required, pushing the hand crank connecting shaft inward disengages the switch contact plate on the hand crank connecting shaft from the touch switch of the handle's position sensor. The external spline head of the hand crank connecting shaft inserts into the spline hole of the second 90° reversing rotary transmission assembly, de-energizing the motor. Rotating the hand crank then enables manual input. When electric input is required, pulling the hand crank connecting shaft outward contacts the switch contact plate on the hand crank connecting shaft with the touch switch of the handle's position sensor, pressing the touch switch. This completely disengages the external spline head of the hand crank connecting shaft from the spline hole of the second 90° reversing rotary transmission assembly, energizing the motor and enabling electric drive of the reducer. During reducer operation, a position sensor continuously monitors the reducer's rotation angle.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
