Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1 to 6, an embodiment of the present invention provides a modular motor assembly, and based on the modular motor assembly, an embodiment of the present invention further provides a motor driving system.
As shown in fig. 1 and 3, the modular motor assembly includes at least one connection unit 100 and at least one motor unit 200. The connection unit 100 includes a power output terminal 110 and at least three power input terminals, and the motor unit 200 is detachably connected to any one of the power input terminals. This modularization motor composition can be with motor structure modularization, and utilize linkage unit 100 to make up a plurality of motor element 200, in order to realize that a plurality of power input end transmissions turn into same power take off 110, thereby according to the required power parameter of actuating mechanism among the actuating system of user's demand, assemble or dismantle motor element 200 in a flexible way on linkage unit 100, in order to realize the unit combination with different quantity, especially with the combination of motor element 200 of different diameters etc., the quick drive system who constitutes to have different parameters (for example power, rotational speed, moment of torsion, size etc.), realize customizing motor product as required, and shorten the design cycle of motor greatly, reduce the degree of difficulty of motor design. Therefore, the modular motor assembly of the present invention realizes the rapid combination of the motor and the rapid selection of the motor parameters by assembling and combining the plurality of motor units 200 by the connecting unit 100, so as to meet the customization requirements of single-piece small-batch motor products.
It can be understood that, in order to achieve reliable power transmission between the connection unit 100 and the motor units 200, and between the respective motor units 200, as shown in fig. 3, it is preferable that the modular motor assembly further includes a connection shaft 300. The connection shaft 300 is connected between the connection unit 100 and the motor unit 200. Further, the modular motor assembly includes at least two motor units 200, as shown in fig. 1. Each motor unit 200 is sequentially connected to the same power input end of the connection unit 100. Wherein, the motor units 200 are connected with the power input end of the connection unit 100 through the connection shaft 300, and the adjacent motor units 200 are connected with each other through the connection shaft 300. The connecting shaft 300 performs mechanical transmission between the respective unit modules (i.e., the motor unit 200 or the connecting unit 100), and preferably, the connecting shaft 300 is a spline shaft, i.e., the outer surface of the connecting shaft 300 is configured as a spline structure, and spline grooves matched with the spline structure of the connecting shaft 300 are configured at the respective shaft ends (e.g., the power input end of the connecting unit 100, and the motor output end 230 and the motor input end 220 of the motor unit 200), so that the connecting shaft 300 is embedded between the respective shaft ends through the spline structure to ensure power transmission reliability.
In one embodiment, as shown in fig. 4, the coupling unit 100 includes a transmission assembly, a first power input 120, a second power input 130, and a third power input 140. The first power input 120 is disposed opposite the power output 110 and the second power input 130 is disposed opposite the third power input 140. The second power input end 130 and the third power input end 140 are respectively adjacent to the position between the first power input end 120 and the power output end 110, and the transmission assembly is respectively connected with the power output end 110, the first power input end 120, the second power input end 130 and the third power input end 140, so that the power of the power input ends in three directions is converged on the same power output end 110 by the transmission assembly, and the effect of converging multiple power inputs is realized.
In one embodiment, as shown in FIG. 4, the transmission assembly includes a drive shaft 102, a first bevel gear 121, a second bevel gear 131, and a third bevel gear 141. The drive shaft 102 is connected between the power output 110 and the first power input 120. The first bevel gear 121 is connected between the driving shaft 102 and the first power input end 120, and can be rotated by the driving of the driving shaft 102. The second bevel gear 131 and the third bevel gear 141 are respectively engaged with two opposite sides of the first bevel gear 121 and are respectively located on two sides of the driving shaft 102, and the second bevel gear 131 is connected with the second power input end 130. In the case where the first power input terminal 120, the second power input terminal 130, and the third power input terminal 140 are respectively connected to the motor unit 200, the power input from the first power input terminal 120 can drive the driving shaft 102 to rotate; meanwhile, the second bevel gear 131 and the third bevel gear 141 are simultaneously engaged with the first bevel gear 121, so that the power input from the second power input end 130 and the power input from the third power input end 140 are respectively transmitted to the driving shaft 102, the powers in three directions are converged and drive the driving shaft 102 to rotate together, and the output gear 111 is connected between the driving shaft 102 and the power output end 110, so that power output is realized.
It can be understood that, because the gear transmission has reversibility, the power output end 110 and any one of the first power input end 120, the second power input end 130 and the third power input end 140 can be replaced as required, that is, in the above-mentioned connection unit 100, any one direction is selected as the power output end 110, and the other directions are selected as the power input ends to be connected with the motor unit 200, so that multi-directional power input driving can be realized and the power can be converged to the same power output end 110. Therefore, the motor unit 200 can be assembled on any end face of the connecting unit 100 according to actual needs, different numbers of unit combinations can be realized, and the flexibility of parameter adjustment of the driving system is improved.
For example, in the coupling unit 100 shown in fig. 7, the power take-off 110 as a power take-off is coupled to one motor unit 200 through a coupling shaft 300, the gear shaft of the first bevel gear 121 of the first power take-off 120 is coupled to one motor unit 200 through a coupling shaft 300, and the gear shaft of the third bevel gear 141 of the third power take-off 140 is coupled to another coupling unit 100 through a coupling shaft 300. It can be seen that in the coupling unit 100 shown in fig. 7, the power output 110, the first power input 120 and the third power input 140 serve as three power inputs, while the second power input 130 serves as a power output.
In one embodiment, as shown in fig. 5, the connection unit 100 further comprises a support base 104, a support bearing 105, a spring collar (not shown), and a plurality of thrust bearings 103.
The support base 104 is sleeved on the driving shaft 102 and is positioned between the power output end 110 and the first bevel gear 121. The outer ring of the support bearing 105 is embedded in the support base 104, the inner ring of the support bearing 105 is sleeved outside the drive shaft 102, so that the inner ring of the support bearing 105 is driven to rotate relative to the outer ring of the support bearing 105 when the drive shaft 102 rotates, and the outer ring of the support bearing 105 is kept still under the action of the support base 104, thereby providing a support base for each bevel gear connected to the support base. Preferably, the support bearing 105 is an angular contact ball bearing. Preferably, the spring collar is inserted between the support base 104 and the outer ring of the support bearing 105. The spring collar provides resilient support and cushioning between the inner wall of the support base 104 and the outer race of the support bearing 105.
In order to effectively increase the structural strength between the second bevel gear 131 and the third bevel gear 141 and the driving shaft 102 in the mutually engaged state of the bevel gear sets, it is preferable that a pair of mounting surfaces capable of being perpendicular to the gear shaft of the second bevel gear 131 and the gear shaft of the third bevel gear 141, respectively, is configured on the outer wall of the support base 104. Inner rings of the thrust bearings 103 are sleeved on the gear shaft extending end of the second bevel gear 131 and the gear shaft extending end of the third bevel gear 141 in a one-to-one correspondence manner, outer rings of the thrust bearings 103 are embedded in the mounting holes 106 on the pair of mounting surfaces in a one-to-one correspondence manner, in the process that the second bevel gear 131 and the third bevel gear 141 respectively generate meshing transmission with the first bevel gear 121 through rotation, the gear shaft of the bevel gear drives the inner rings of the thrust bearings 103 to rotate relative to the outer rings, so that the gear shaft of the bevel gear rotates relative to the supporting seat 104, and the supporting seat 104 cannot rotate and move axially or radially. On one hand, the structural reliability of the bevel gear sets in the mutually meshed state is improved, and on the other hand, the bevel gears can simultaneously push the side surfaces of the driving shaft 102 from multiple directions by means of the assembling relation among the power bearing 103, the supporting seat 104 and the supporting bearing 105, so that the driving shaft 102 is prevented from being bent in the transmission process.
It will be appreciated that the coupling unit 100 of the present invention may be provided with more than three power inputs. That is, one power input end is disposed opposite to the power output end 110 and connected through the driving shaft 102, and the other power input ends are disposed at the side of the driving shaft 102, and it is only necessary to respectively construct corresponding mounting surfaces perpendicular to the axial direction of the gear shaft of each bevel gear on the basis of the gear shaft end direction of each bevel gear on the external contour of the supporting seat 104, and the end of the gear shaft of each bevel gear is respectively mounted in the mounting surfaces through the thrust bearings 103 in a one-to-one correspondence manner, so that more bevel gears can be engaged at the side of the driving shaft 102 of the connection unit 100, and further, the combined connection of more motor units 200 through the connection unit 100 is realized.
In one embodiment, the connection unit 100 further comprises a first housing 101 arranged in a rectangular shape. The transmission assembly is mounted in the inner cavity of the first housing 101. The first housing 101 includes at least two pairs of oppositely disposed mounting surfaces, and each pair of mounting surfaces is adjacent to each other, wherein one pair of mounting surfaces is provided with a power output end 110 and a power input end, and the other power input ends are respectively located on the other mounting surfaces. Further, in order to facilitate assembly and optimize the structural configuration, as shown in fig. 6, it is preferable that the motor unit 200 includes a second housing 201 arranged in a rectangular shape, and the second housing 201 includes a pair of connection surfaces matching with any one of the mounting surfaces of the first housing 101, and the pair of connection surfaces are respectively provided with a motor input end 220 and a motor output end 230. The first shell 101 and the second shell 201 which are arranged in a rectangular shape can restrict the positions of the power input end and the power output end 110, and are more favorable for mutual assembling and matching of the motor unit 200 and the connecting unit 100, so that the assembled modular motor assembly has a more standard structure, and mutual matching and assembling among multiple groups of modular motor assemblies are facilitated.
It will be appreciated that each mounting face is preferably individually closed by a cover plate 160 to protect the internal components. A through hole is formed at the center of the cover plate 160, and the connection shaft 300 is inserted into the through hole and is lockingly connected between two adjacent sets of connection units 100 or between one connection unit 100 and one motor unit 200 by a spline structure. Further, it is preferable that the cover plate 160 is fixedly mounted on the mounting surface of the connection unit 100 by a plurality of locking screws.
It will be appreciated that the preferred motor unit 200 includes a motor shaft 210, the motor shaft 210 being mounted within the second housing 201 and connected between the motor input 220 and the motor output 230. Preferably, a motor rotor is disposed outside the motor shaft 210 to achieve the purpose of power output.
It can be understood that, in order to flexibly increase or decrease the number of motor units 200 at one power input end of the connection unit 100 during the assembly process, even if the parameters at one power input end are adjustable, it is preferable to continuously connect a plurality of motor units 200 at the same power input end. Specifically, between two adjacent sets of motor units 200, the power output end 110 of the next motor unit 200 is connected to the power input end of the previous motor unit 200 through the connecting shaft 300, so that the motor units 200 can be connected in sequence.
As shown in fig. 1, a motor driving system according to an embodiment of the present invention includes a plurality of sets of modular motors as described above, and the sets of modular motors are connected to each other. In the adjacent two groups of modular motor compositions, the power output end 110 of the connecting unit 100 composed of one group of modular motor is connected with any power input end of the connecting unit 100 of the other group of modular motor compositions to realize power transmission between the modular motor compositions of each group, namely, by increasing the modular motor compositions, parameter expansion of a motor driving system is realized, motor driving parameters (such as power, rotating speed, torque, size and the like) are proportionally expanded, and parameter adjustment is realized more flexibly and conveniently. In addition, by arranging the modular motor assembly, the motor driving system has all the advantages of the modular motor assembly, and is not described herein again.
