Description

Technical Field

[0001] The utility model relates to the field of spiral transmission, in particular to a transmission sleeve assembly, a transmission assembly and a solar energy device. Background Art

[0002] The helical transmission assembly includes a transmission sleeve and an outer sleeve. The outer circumference of the transmission sleeve is provided with a helical spline, and the inner circumference of the outer sleeve is provided with a helical spline that matches the transmission sleeve. The outer sleeve is sleeved on the transmission sleeve and the two have the same axis. When the transmission sleeve moves linearly along its own axis, the outer sleeve rotates around its axis through the cooperation of the inner and outer helical splines.

[0003] In terms of the processing of helical splines, it is usually easier to process the outer helical splines of the transmission sleeve, but it is difficult to achieve high processing accuracy for the outer sleeve because the helical splines need to be processed on the inner circumference with limited space. Therefore, a large gap will be generated between the transmission sleeve and the outer sleeve. This gap will cause the transmission sleeve or the outer sleeve to shake in the helical spline transmission, and further affect the movement state of subsequent connecting parts.

[0004] Therefore, how to design a structure that can reduce the transmission clearance between the transmission sleeve and the outer sleeve has become a technical problem that needs to be solved urgently. Utility Model Content

[0021] The beneficial effects of the utility model are:

[0022] 1. Since the connection assembly is provided with an elastic component, the transmission sleeve is affected by the elastic force when it moves, so that the first sleeve automatically moves away from or close to the second sleeve within a limited range (similar to expansion and contraction), without the intervention of operators, reducing maintenance work. When subjected to external impact force, since the threads on the first sleeve and the second sleeve are respectively matched with different sides of the keyway, the elastic component absorbs the external impact force, reducing the direct impact of the external impact force on various parts of the transmission assembly.

[0023] 2. In the embodiment where the transmission sleeve is provided with both threads and spur splines, the first sleeve and the second sleeve will rotate relative to each other while moving away from or approaching each other within a limited range under the action of elastic force. Since the transmission sleeve is also provided with spur splines cooperating with the spline shaft, the relative rotation of the first sleeve and the second sleeve causes the spur splines in the transmission sleeve to abut against the spline shaft. This abutting effect will further enhance the tightness of the fit between the threads and the spur splines, thereby further reducing the fit clearance between the transmission sleeve and the spline shaft and enhancing the working stability of the transmission assembly.

[0042] The present application is further described in detail below in conjunction with specific drawings.

[0043] As a first aspect of the present embodiment, a transmission sleeve assembly 1 is provided, comprising a first sleeve 11 and a second sleeve 12 arranged coaxially, wherein the outer circumference or the inner circumference of the first sleeve 11 and the second sleeve 12 is provided with a thread 14 with a consistent pitch; further comprising a connecting assembly 13 arranged between the first sleeve 11 and the second sleeve 12, wherein the connecting assembly 13 comprises a ring sleeve 131 and a first elastic member 132, wherein the ring sleeve 131 is coaxially arranged between the first sleeve 11 and the second sleeve 12, and the first elastic member 132 is arranged on the ring sleeve 13 1, one end of the first sleeve 11 close to the ring sleeve 131 is provided with a first groove 111, and one end of the second sleeve 12 close to the ring sleeve 131 is provided with a second groove; the transmission sleeve assembly 1 also includes at least one first clamping member 16 and at least one second clamping member 17, one end of the first clamping member 16 is connected to the first groove 111, and the other end of the first clamping member 16 is connected to the connecting assembly 13; one end of the second clamping member 17 is connected to the second groove, and the other end of the first clamping member 16 is connected to the connecting assembly 13.

[0044] Regarding the first sleeve 11 and the second sleeve 12: The outer circumference or inner circumference of the first sleeve 11 and the second sleeve 12 is provided with a thread 14 with the same pitch. When the outer circumference of the first sleeve 11 is provided with a thread 14, the outer circumference of the second sleeve 12 is also provided with a thread 14 correspondingly, or when the inner circumference of the first sleeve 11 is provided with a thread 14, the inner circumference of the second sleeve 12 is also provided with a thread 14 correspondingly, and when one end of the first sleeve 11 abuts against one end of the second sleeve 12 and the two are coaxially arranged, the thread 14 provided on the first sleeve 11 and the thread 14 provided on the second sleeve 12 are arranged coaxially. The threads 14 on the sleeve 12 are located on the same spiral curve, that is, when the transmission sleeve assembly 1 is in a static state not connected to an external component, there is a certain distance between the first sleeve 11 and the second sleeve 12, and the threads 14 on the circumference of the two are not continuous, but have a certain misalignment; when the transmission sleeve assembly 1 proposed in this embodiment is used, the threads 14 on the first sleeve 11 and the threads 14 on the second sleeve 12 form a spiral transmission fit with the external component, and the above-mentioned misalignment can enable the transmission sleeve assembly 1 and the external component to achieve a tight transmission state, thereby reducing the requirements for the processing accuracy of the spiral transmission fit.

[0045] In most embodiments, the inner diameter or outer diameter of the first sleeve 11 and the second sleeve 12 are also consistent, wherein the inner diameter or outer diameter is associated with the setting position of the thread 14. The thread 14 can be understood as a structure of a combination of protrusions and depressions. When the thread 14 is arranged on the inner circumference of the first sleeve 11, the inner diameter of the first sleeve 11 refers to the distance from the center of the circle to the depression of the thread 14 on the radial cross section of the axis of the first sleeve 11. When the thread 14 is arranged on the outer circumference of the first sleeve 11, the outer diameter of the first sleeve 11 refers to the distance from the center of the circle to the depression of the thread 14 on the radial cross section of the axis of the first sleeve 11. The same is true for the second sleeve 12.

[0046] If the thread 14 is provided on the inner circumference of the first sleeve 11 and the second sleeve 12, the transmission sleeve assembly 1 is usually used for connecting with the screw drive. Accordingly, the first sleeve 11 and the second sleeve 12 can be connected with the screw drive respectively, and the inner diameters of the first sleeve 11 and the second sleeve 12 are consistent. Figure 1 and Figure 5 In the embodiments of the two transmission sleeve assemblies 1, the first sleeve 11 and the second sleeve 12 can be transmission-connected to the outer cylinder 2 with a matching thread 14 on the outside. The thread 14 is arranged on the outer circumferential surface of the first sleeve 11 and the second sleeve 12, and the outer diameters of the first sleeve 11 and the second sleeve 12 are consistent.

[0047] The helix angle is the angle between the axis of the transmission sleeve assembly 1 and the tangent of the thread 14. In some embodiments, the helix angle of the thread 14 is greater than 0 degrees and less than 45 degrees. In this case, the thread 14 can be understood as a helical spline. Further, in an embodiment where the helix angle of the thread 14 is 13 degrees, only a relatively small force needs to be applied in the axial direction of the transmission sleeve assembly 1 to achieve rotational cooperation between the transmission sleeve assembly 1 and the external component, thereby achieving stable transmission.

[0048] like Figures 1 to 6 As shown, in some embodiments, when the outer circumference of the transmission sleeve assembly 1 is provided with a thread 14, the inner circumference of the transmission sleeve assembly 1 is provided with a spur spline 15, and the spur spline 15 can be conveniently and quickly connected to or transmitted with an external component. When the spur spline 15 is used for connection, the first sleeve 11 and the second sleeve 12 can move relative to the external connected component along the spur spline 15, and through this relative movement, the thread 14 of the transmission sleeve and the external component are more closely matched. When the spur spline 15 is used for transmission, while having the connection function of the spur spline 15, the first sleeve 11 and the second sleeve 12 can not only move relative to the externally connected parts along the spur spline 15, but the entire transmission sleeve assembly 1 can also move along the spur spline 15. At this time, since the first sleeve 11 and the second sleeve 12 have relative rotational movement, the relative rotation of the first sleeve 11 and the second sleeve 12 allows the spur spline 15 in the transmission sleeve to abut against the spline shaft 3. This abutment will further enhance the tightness of the fit between the thread 14 and the spur spline 15, thereby further reducing the fit clearance between the transmission sleeve and the spline shaft 3, and enhancing the stability of the transmission sleeve assembly 1 when it moves and works along the spur spline 15.

[0049] In such Figure 3 In some embodiments shown, the thread 14 is an involute thread 14 and / or the spur spline 15 is an involute spline. The involute thread 14 (or helical spline) provides a larger contact area in transmitting torque and motion, and also has the advantages of self-centering, high installation accuracy and high load-bearing capacity.

[0050] About the connecting assembly 13: The main function of the connecting assembly 13 is to set the first elastic member 132 (and / or the second elastic member 133) and connect the first sleeve 11 and the second sleeve 12. The connecting assembly 13 includes a sleeve 131 and a first elastic member 132. It should be noted that when the thread 14 is set on the inner circumference of the first sleeve 11 and the second sleeve 12, the radius of the inner circumference of the sleeve 131 cannot be greater than the inner diameter of the first sleeve 11 (second sleeve 12); when the thread 14 is set on the outer circumference of the first sleeve 11 and the second sleeve 12, the radius of the outer circumference of the sleeve 131 cannot be greater than the outer diameter of the first sleeve 11 (second sleeve 12), that is, the sleeve 131 cannot affect the spiral transmission between the thread 14 and the external components. In some embodiments, the annular sleeve 131 is further provided with a mounting portion for connecting with the active component, and the entire transmission sleeve assembly 1 is driven to move by the annular sleeve 131. When the mounting portion is provided on the inner circumference of the annular sleeve 131, the mounting portion connects the annular sleeve 131 to the screw nut 5 through a connecting member, wherein the connecting member can be as follows: Figure 8 The ear piece 6 shown drives the transmission sleeve assembly 1 to move when the screw rod 4 rotates. This embodiment reduces the space occupied and improves the integration of the structure.

[0051] The materials and structures of the first clamping member 16 and the second clamping member 17 are the same or similar. In the present embodiment, in order to avoid redundancy, only the connection relationship among the first clamping member 16, the first sleeve 11 and the connecting component 13 is described. Those skilled in the art can refer to the connection relationship among the first clamping member 16, the first sleeve 11 and the connecting component 13 to derive the connection relationship among the second clamping member 17, the second sleeve 12 and the connecting component 13.

[0052] like Figure 2 As shown, in some embodiments, the first clamping member 16 is made of a flexible material, and the flexible material can be a steel wire rope, a fiber rope, etc. One end of the first clamping member 16 having flexibility is connected to the connecting assembly 13, and the other end is connected to the first sleeve 11, thereby limiting the maximum spacing between the first sleeve 11 and the connecting assembly 13 along the axial direction of the first sleeve 11. Since the flexible material is deformable, the first clamping member 16 made of the flexible material can be fixedly connected to the connecting assembly 13 and the first sleeve 11 respectively. When the first sleeve 11 and the second sleeve 12 are away from or close to each other, the first clamping member 16 is deformed, and the transmission sleeve assembly 1 and the external component are closely matched. When the transmission sleeve assembly 1 and the external component remain stationary, the first clamping member 16 stops deforming. This embodiment using flexible materials is suitable for scenes with complex environments, limited layouts, or frequent movement.

[0053] like Figure 2 , Figure 5 and Figure 6In some embodiments shown, the first clamping member 16 and / or the second clamping member 17 are made of a rigid material, which may be an alloy, steel, etc. Since the deformation range of the rigid material is small, at least one of the two ends of the first clamping member 16 needs to be movably connected to the first sleeve 11 or the connecting assembly 13. The shape of the first clamping member 16 and / or the second clamping member 17 is as follows: Figure 5 and Figure 6 The strip-shaped one shown in FIG. 1 may also be Figure 1 and Figure 2 Since the strength of rigid materials is usually high, the first clamping member 16 and / or the second clamping member 17 with a certain rigidity can be applied to application scenarios with larger structures and higher loads.

[0054] In such Figure 4 In some of the embodiments shown, in order to facilitate the connection of the first clamping member 16 to the connecting assembly 13, the connecting assembly 13 also includes a first clamping ring 134, and the first clamping ring 134 and the first sleeve 11 are respectively arranged at the two ends of the ring sleeve 131, that is, the first clamping ring 134 is arranged between the second sleeve 12 and the ring sleeve 131, and a third clamping groove 1341 for connecting to the other end of the first clamping member 16 is provided on the first clamping ring 134. Similarly, a second clamping ring 135 is also provided between the first sleeve 11 and the ring sleeve 131, and a fourth clamping groove for connecting to the other end of the second clamping member 17 is provided on the second clamping ring 135.

[0055] When the first snap ring 134 and / or the second snap ring 135 are provided, the first elastic member 132 can be provided between the first snap ring 134 and the ring sleeve 131, or between the connecting assembly 13 and the first sleeve 11, or the first elastic member 132 can also be provided between the second snap ring 135 and the ring sleeve 131.

[0056] In such Figure 4 In some of the embodiments shown, the connecting assembly 13 also includes a second elastic member 133, which is disposed at one end of the ring sleeve 131 away from the first elastic member 132. At this time, one connecting end of the second clamping member 17 is connected to the second elastic member 133, and the other connecting end of the second clamping member 17 is connected to the second sleeve 12.

[0057] In some embodiments, Figure 2 and Figure 6 As shown, a plurality of first clamping members 16 and second clamping members 17 are provided. Furthermore, the plurality of first clamping members 16 and second clamping members 17 are arranged in a circular array, which can make the connection force of the connecting assembly 13, the first sleeve 11 and the second sleeve 12 more uniform, and make the transmission cooperation between the transmission sleeve assembly 1 and the external components more stable and safe.

[0058] In some embodiments, the first elastic member 132 and / or the second elastic member 133 is a wave spring. Compared with other springs, the wave spring has a more compact structure and is suitable for providing a stronger elastic force in a limited space, and is particularly suitable for occasions where the installation space is limited.

[0059] Regarding the connection position of the first clamping member 16 (the second clamping member 17) on the connection assembly 13, two situations are described above. In the first situation, one end of the first clamping member 16 is connected to the elastic member, and the other end is connected to the first sleeve 11. In the second situation, one end of the first clamping member 16 is connected to the first clamping ring 134, and the other end is connected to the first sleeve 11. In addition, there is a third situation: one end of the first clamping member 16 is connected to the ring sleeve 131, and the other end is connected to the first sleeve 11. At this time, the third situation can also achieve technical effects similar to the first and second situations described above.

[0060] In some embodiments, a protective sleeve is further included, which is sleeved on the ring sleeve 131 to prevent the connecting member from leaving the transmission sleeve assembly 1. The protective cover can also prevent the connecting assembly 13, the first clamping member 16 and the second clamping member 17 from being invaded by wind, sand, dust and the like.

[0061] As a second aspect of this embodiment, Figure 7 and Figure 8 As shown, a transmission assembly is proposed, including the above-mentioned transmission sleeve assembly 1, and also including a spline shaft 3, a screw rod 4, a screw nut 5, an ear piece 6 and an outer tube 2, the screw rod 4 is threadedly connected to the screw nut 5, one end of the ear piece 6 is connected to the screw nut 5, and the other end is connected to the transmission sleeve assembly 1, the transmission sleeve assembly 1 is sleeved on the spline shaft 3, the inner circumference of the outer tube 2 is provided with a structure that cooperates with the thread 14, and the outer tube 2 is sleeved on the transmission sleeve assembly 1.

[0062] In some embodiments, the ear piece 6 is connected to the mounting portion of the inner circumference of the ring sleeve 131. In other embodiments, the length of the axis of the ear piece 6 is greater than the transmission sleeve assembly 1, and the ear piece 6 is provided with a fifth slot near the transmission sleeve assembly 1, and both ends of the transmission sleeve assembly 1 are inserted into the fifth slot. When the ear piece 6 drives the transmission sleeve assembly 1 to move in the outer tube 2, the first sleeve 11 and the second sleeve 12 move away from or close to each other, and the threads 14 on the first sleeve 11, the threads 14 on the second sleeve 12 and the outer tube 2 realize tight spiral transmission.

[0063] As a third aspect of this embodiment, a solar energy device is proposed, including the above-mentioned transmission assembly, and also including a photovoltaic panel and a column, wherein the fixed end of the transmission assembly is connected to the column, and the moving end of the transmission assembly is connected to the photovoltaic panel.
