Description

Technical Field

[0001] The present invention belongs to the technical field of transmission, and particularly relates to a transmission module and an installation method thereof. Background Art

[0002] The transmission module is an important part of the transmission system. The existing transmission structure cannot achieve assembly for the working conditions of the two-end fixed support structure. The use of a positioning bushing can achieve precise positioning of each conveying module, but the number of transmission wheels assembled on a single transmission shaft is limited and cannot be maximized, resulting in poor structural compactness and inability to meet the transmission or conveying requirements of small-sized goods. Moreover, the use of a split-type locking positioning ring cannot achieve precise and reliable positioning of each conveying module, and the assembly operation is complex and inefficient. Therefore, the existing transmission structure can no longer meet the rapid development needs of modern transmission systems. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a transmission module and an installation method thereof.

[0004] The specific solutions are as follows:

[0005] A transmission module includes a support frame and a transmission shaft arranged on the support frame. A transmission wheel and a positioning mechanism are arranged on the transmission shaft. The positioning mechanism includes a first positioning unit and a second positioning unit. The first positioning unit is fixed at both ends of the transmission shaft, and the second positioning unit is fixed between the two first positioning units. Transmission wheels are fixed between the first positioning unit and the support frame and between every two second positioning units.

[0006] The first positioning unit and the second positioning unit are evenly fixed on the transmission shaft.

[0007] Both the first positioning unit and the second positioning unit include a positioning groove and a positioning block. Among them, the positioning block is in snap-fit connection with the positioning groove. The positioning groove is fixed on the transmission shaft. The positioning groove is a groove, and the positioning block is detachably connected to the transmission shaft through the positioning groove.

[0008] A screw and a screw mounting hole are arranged on the positioning block. A through hole is arranged on the transmission shaft and within the positioning groove. The screw mounting hole corresponds to the through hole, and the positioning block is detachably connected to the positioning groove through the screw.

[0009] The positioning grooves are symmetrically arranged on both side surfaces of the transmission shaft. The positioning block is a U-shaped positioning block, and the U-shaped positioning block is in snap-fit connection with the positioning grooves on both side surfaces of the transmission shaft.

[0010] The cross-section of the transmission shaft and the cross-section of the axle center hole of the transmission wheel are both regular n-sided polygons, where n is an even number greater than or equal to six.

[0011] Both ends of the transmission shaft are also provided with bearings and bushings. The transmission shaft is rotatably connected to the support frame through the bearings, and both the transmission shaft and the bearings are sleeved and connected with the bushings.

[0012] The bearing is a stepped bearing, the bushing is a stepped bushing, and snap rings are also arranged at both ends of the transmission shaft. The snap rings are detachably connected to the transmission shaft.

[0013] There are a pair of support frames, and the pair of support frames are symmetrically fixed at both ends of the transmission shaft.

[0014] An installation method for a transmission module includes the following steps:

[0015] Step S1): Pass one end of the transmission shaft through any one of the support frames, and make one end of the transmission shaft located between the two support frames;

[0016] Step S2): Sequentially insert multiple transmission wheels from one end of the transmission shaft to the middle position of the transmission shaft, so that the multiple transmission wheels are located between the two support frames;

[0017] Step S3): Fix both ends of the transmission shaft on the two support frames through bearings and bushings respectively;

[0018] Step S4): Sequentially slide the transmission wheels along the transmission shaft to the first positioning unit and the second positioning unit respectively. At the same time, engage the positioning block with the positioning groove and perform screw fastening connection.

[0019] The present invention discloses a transmission module and its installation method. A first positioning unit and multiple groups of second positioning units are arranged on the transmission shaft. The number of second positioning units can be increased or decreased according to the size of the goods to be transported, so as to adapt to the transmission of different goods sizes. The positioning card slot on the transmission shaft is engaged with the positioning block, and the positioning groove and the positioning block are fixedly connected by screws, which can meet the requirements of accurate and reliable positioning of the transmission wheel on the transmission shaft. The support and positioning structure of the stepped bearing, stepped positioning sleeve and transmission shaft is adopted to solve the contradiction between the positioning size of the inner ring of the stepped bearing being smaller than the positioning size of the transmission wheel, effectively improving the process performance of the support frame and the transmission shaft, reducing the manufacturing cost, and having the advantages of simple structure and easy disassembly and assembly.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0032] As Figure 1 shown, a transmission module includes a support frame 1 and a transmission shaft 2 provided on the support frame 1. A transmission wheel 3 and a positioning mechanism 6 are provided on the transmission shaft 2. The positioning mechanism 6 includes a first positioning unit 4 and a second positioning unit 5. The first positioning unit 4 is fixed at both ends of the transmission shaft 2, and the second positioning unit 5 is fixed between the two first positioning units 4. Transmission wheels 3 are fixed between the first positioning unit 4 and the support frame 1 and between every two second positioning units 5.

[0033] The first positioning unit 4 and the second positioning unit 5 are uniformly fixed on the transmission shaft 2, and the support frame 1 is a pair, and the pair of support frames 1 are symmetrically fixed at both ends of the transmission shaft 2.

[0034] In this embodiment, preferably, the number of the first positioning units 4 is two, which are respectively fixed at both ends of the transmission shaft 2. The number of the second positioning units 5 is four. Transmission wheels 3 are fixed between the first positioning unit 4 and the support frame 1 and between the second positioning units 5. Therefore, in this embodiment, the number of the transmission wheels 3 on the transmission shaft 2 is preferably four. The four transmission wheels are accurately fixed on the transmission shaft 2 through the first positioning unit 4 and the second positioning unit 5. When the transmission shaft 2 rotates, it will drive the four transmission wheels to rotate around the axis direction of the transmission shaft 2 at the same time. At the same time, the transmission wheels 3 can convey the goods placed on the transmission wheels 3. According to the size of the goods to be conveyed, the wheel spacing between the transmission wheels 3 can be changed so that the transmission module can be adjusted according to the size of the goods.

[0035] The specific adjustment method of the transmission module is as follows:

[0036] According to the minimum size of the goods to be conveyed, determine the minimum wheel spacing between every two transmission wheels 3. According to the obtained minimum wheel spacing, determine the length of the transmission shaft 3 and the spacing between the first positioning unit 4 and the second positioning unit 5 on the transmission shaft 3, and according to the thickness of the transmission wheels 3, determine the spacing between the two second positioning units 5. In this way, for different sizes of goods, after adjusting the transmission module, it can be adapted to convey goods of different sizes.

[0037] As Figures 2 to 5 shown, both the first positioning unit 4 and the second positioning unit 5 include a positioning groove 9 and a positioning block 7. Among them, the positioning block 7 is in snap-fit connection with the positioning groove 9. The positioning groove 9 is fixed on the transmission shaft 2. The positioning groove 9 is a groove, and the positioning block 7 is detachably connected to the transmission shaft 2 through the positioning groove 9.

[0038] The terms "first" and "second" in this embodiment are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0039] A screw 8 and a screw mounting hole are provided on the positioning block 7. A through hole is provided on the transmission shaft 2 and located in the positioning groove 9. The screw mounting hole corresponds to the through hole, and the positioning block 7 is detachably connected to the positioning groove 9 through the screw 8.

[0040] As Figures 6 to 8 shown, the positioning grooves 9 are symmetrically arranged on both side surfaces of the transmission shaft 2. The positioning block 7 is a U-shaped positioning block, and the U-shaped positioning block is in snap-fit connection with the positioning grooves 9 on both side surfaces of the transmission shaft 2.

[0041] The positioning groove 9 is a flat positioning groove. On both sides of the U-shaped positioning block, there are clamping blocks that cooperate with the flat positioning groove 9. At the bottom inside the U-shaped positioning block, there is a bayonet that cooperates with and clamps the transmission shaft 2. As Figure 3 shown, during the actual installation process, the U-shaped positioning block is inserted into the positioning groove 9 on the transmission shaft 2 so that the U-shaped positioning block and the transmission shaft 2 are clamped together. After the clamping is completed, the screw 8 is then tightly connected through the screw mounting hole and the through hole, so that the U-shaped positioning block is firmly clamped on the transmission shaft 2, effectively ensuring the precise positioning of the transmission wheel 3 on the transmission shaft 2. In this embodiment, through holes are also provided on the transmission shaft 2. When the positioning block 7 is clamped to the transmission shaft 2, the through holes correspond to the screw mounting holes on the positioning block 7, so as to enable the tight installation of the screw and achieve the stable clamping of the positioning block 7 and the transmission shaft 2.

[0042] The cross-section of the transmission shaft 2 and the cross-section of the axle center hole of the transmission wheel 3 are both regular n-sided polygons, where n is an even number greater than or equal to six. In this embodiment, the cross-section of the transmission shaft 2 is preferably a regular hexagon, and the cross-section at the axle center hole of the transmission wheel 3 is also preferably a regular hexagon. In this way, the transmission wheel 3 can be installed in cooperation with the transmission shaft 2. The cross-section of the transmission shaft 2 being a regular n-sided polygon can not only further achieve the stable clamping between the transmission shaft 2 and the transmission wheel 3, but also facilitate the rotational transmission of the transmission shaft 2, avoiding the phenomenon of the transmission wheel 3 slipping on the transmission shaft 2 during the goods transmission process.

[0043] As Figure 9 shown, bearings 11 and bushings 10 are also provided at both ends of the transmission shaft 2. The transmission shaft 2 is rotatably connected to the support frame 1 through the bearings 11, and both the transmission shaft 2 and the bearings 11 are sleeved and connected to the bushings 10.

[0044] The bearing 11 is a stepped bearing, and the bushing 10 is a stepped bushing. Spring retaining rings 12 are also provided at both ends of the transmission shaft 2. The spring retaining rings 12 are detachably connected to the transmission shaft 2. Specifically, spring grooves are provided at both ends of the transmission shaft 2, and the spring retaining rings 12 are detachably connected to the transmission shaft 2 through the spring grooves. The spring retaining rings 12 can position the axial direction of the stepped bearing, avoiding the axial movement of the bearing in the axial direction during the transmission process.

[0045] In this embodiment, the stepped end of the stepped bearing is located outside the support frame 1 and abuts against the support frame 1, and then the axial direction of the stepped bearing is limited by the spring retaining ring 12. The stepped end of the stepped bushing is located at one end of the stepped bearing to axially position the other end of the stepped bearing. The stepped bearing realizes two-way positioning in the support frame 1 through the spring retaining ring 12 and the stepped bushing, ensuring the stable assembly of both ends of the transmission shaft 2 in the support frame 1 and avoiding the axial movement of the transmission shaft 2 during the transmission process.

[0046] As shown Figures 10 to 11 in the figure, the driving wheel 3 is an omnidirectional wheel. The omnidirectional wheel includes a hub and a driven wheel. The outer circumference of the hub is evenly provided with 3 or more hub teeth. A driven wheel is installed between every two hub teeth. The radial direction of the driven wheel is perpendicular to the tangent direction of the outer circumference of the hub. The omnidirectional wheel is a driving wheel with a simple structure, a wide range of applications, and can move in many different directions.

[0047] The specific installation method of the transmission module includes the following steps:

[0048] Step S1): Pass one end of the transmission shaft 2 through any support frame 1, and make one end of the transmission shaft 2 located between the two support frames 1; preferably, pass the transmission shaft 2 through the support frame 1 at the left end, and make the transmission shaft 2 extend a certain dimension between the two support frames 1, so as to facilitate the installation and assembly of the driving wheel 3; in this embodiment, the left end and the right end are used as reference directions according to the left and right directions in Figure 1 in order to facilitate description, and are not limited to the left end or the right end only;

[0049] Step S2): Sequentially insert a plurality of driving wheels 3 from one end of the transmission shaft 2 to the middle position of the transmission shaft 2, so that the plurality of driving wheels 3 are located between the two support frames 1; in this embodiment, sequentially insert four driving wheels 3 from the right end of the transmission shaft 2 into the transmission 2, and move the driving wheels 3 to the middle position of the transmission shaft 2;

[0050] Step S3): Fix the two ends of the transmission shaft 2 to the two support frames 1 through bearings 11 and shaft sleeves 10 respectively; specifically, pass the two ends of the transmission shaft 2 through the support frames 1 located at both ends of the transmission shaft 2, and then sequentially insert the stepped positioning shaft sleeves from both ends of the transmission shaft 2 and press them against the stepped surfaces of the transmission shaft 2; then, press the stepped bearings into the support frames 1 from both ends of the transmission shaft 2 respectively, and make the stepped end surfaces of the stepped bearings closely adhere to the support end surfaces of the support frames 1;

[0051] Use a circlip pliers to install the snap ring 12 into the card slots at both ends of the transmission shaft to realize the positioning and assembly of the stepped shaft;

[0052] Step S4): Slide the driving wheels 3 along the transmission shaft 2 to the first positioning unit 4 and the second positioning unit 5 respectively, and at the same time, engage the positioning block 7 with the positioning groove 9 and tighten the connection with screws 8.

[0053] In this embodiment, four driving wheels 2 are slid along the transmission shaft 3 to the set positions respectively, and then are engaged through the cooperation of the U-shaped positioning block and the positioning groove, and the positioning holes and the positioning grooves are fixedly connected through screws.

[0054] The disassembly process of the transmission module is the reverse process of its assembly, featuring convenient disassembly, easy maintenance, and simple operation.

[0055] The present invention discloses a transmission module and its installation method. A first positioning unit and multiple groups of second positioning units are provided on the transmission shaft. The number of second positioning units can be increased or decreased according to the size of the transported goods, so as to adapt to the transmission of different goods sizes. The positioning slot on the transmission shaft is engaged with the positioning block in a snap-fit manner, and the positioning slot and the positioning block are fixedly connected by screws, which can meet the requirements of accurate and reliable positioning of the transmission wheel on the transmission shaft. The support and positioning structure of the stepped bearing, stepped positioning sleeve and transmission shaft is adopted to solve the contradiction between the inner ring positioning size of the stepped bearing being smaller than the positioning size of the transmission wheel, effectively improving the process performance of the support frame and transmission shaft and reducing the manufacturing cost. Compared with the traditional transmission structure, the transmission module of the present invention has the beneficial effects of simple structure, good flexibility, easy loading and unloading, compact structure, and accurate and reliable positioning, and can also meet the rapid development needs of modern transmission systems, having very good engineering application prospects.

It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
