Technical Field

The invention relates to the technical field of planetary row transmission equipment, in particular to a reducer with an anti-abrasion prime number double-sun-gear planetary row and specifically defining the gear tooth array combination of gears.

Background

The common planet row comprises three parts, namely a sun gear, an inner gear ring and a planet carrier with planet gears. The dual-sun-wheel planet row for reducing the abrasion quality is provided with a left sun wheel, a right sun wheel and a planet carrier with variable line speed planet wheels, wherein each variable line speed planet wheel comprises a left planet wheel and a right planet wheel, namely the left planet wheel is connected with the right planet wheel to form each variable line speed planet wheel; when the rotating speeds of the left planet wheel and the right planet wheel are the same and are not zero, the reference circle linear speeds of the left planet wheel and the right planet wheel are different; the left planet wheel is meshed with the left sun wheel, the right planet wheel is meshed with the right sun wheel, and the left sun wheel is not meshed with the right sun wheel. The planet carrier is connected with the input end, one sun gear is connected with the locking end, the other sun gear is connected with the output end, and the double-sun-gear planet row with the abrasion reduction prime number can be used as a speed reducer. However, each of the double-sun-gear planetary rows with the wear-reduction prime number is not a speed reducer according to the input and output locking connection method, and a certain gear tooth array combination of each part is required as a condition, namely the specific speed reducer can be formed only by specifically determining the gear tooth array combination of each part. In the speed reducer, the tooth array combination of each gear is accurately arranged, so that the abrasion of the speed reducer during operation is reduced, and the speed reducer is called an abrasion-reducing prime number double-inner-gear-ring planetary-row speed reducer.

Disclosure of Invention

The invention aims to specifically and definitely reduce the gear tooth combination of each gear of a prime number double-sun-gear planetary reducer in a list form, and the total number is 110. The abrasion of the decelerator in operation is reduced. The gear tooth combination of 110 kinds of gear teeth proposed by the invention is completely different from the gear tooth combination of 1505 kinds of gear teeth in the double-sun gear variable-line-speed planetary reducer invented by the inventor.

The double-sun-wheel planet row speed reducer with the abrasion-reducing prime number comprises an abrasion-reducing prime number double-sun-wheel planet row, an input end, an output end and a locking end. The double-sun-wheel planet row with the abrasion-reducing prime numbers comprises a left sun wheel, a right sun wheel and a planet carrier with a variable-line-speed planet wheel; each variable line speed planet wheel on the planet carrier comprises a left planet wheel and a right planet wheel, namely the left planet wheel is connected with the right planet wheel to form each variable line speed planet wheel; the left planet wheel is meshed with the left sun wheel, the right planet wheel is meshed with the right sun wheel, and the left sun wheel is not meshed with the right sun wheel. The input and output locking connection method of the abrasion-reduction prime number double-sun-wheel planetary gear row as the speed reducer comprises the following steps: the planet carrier is connected with the input end, one sun gear is connected with the output end, and the other sun gear is connected with the locking end. The connection is realized by a mechanical connection device, so that the rotating speeds of the two parts are completely the same. Parameters such as the tooth number, the gear module and the reference circle diameter of the left planet gear and the right planet gear are not required to be the same, and parameters such as the tooth number, the gear module and the reference circle diameter of the left sun gear and the right sun gear are not required to be the same. The number of the variable-speed planetary gears is not less than two, and usually two, three, four or more (the number of the variable-speed planetary gears is not less than two, usually two, three, four or more). When the rotating speeds of the left planet wheel and the right planet wheel are the same and are not zero, the reference circle linear speeds of the left planet wheel and the right planet wheel are different. The planet carrier and the variable-line-speed planet wheel are in a relation that one is a shaft and the other is a bearing; in fig. 1, 3 the planet carrier is schematically shown as a bearing and the variable speed planet is shown as an axle; in fig. 2, 4 the carrier is shown as a shaft and the variable speed planetary gear is shown as a bearing.

The abrasion-reduction prime number double-sun-wheel planetary row can be used as a speed reducer by adopting the input-output locking connection method, but each abrasion-reduction prime number double-sun-wheel planetary row is not necessarily a speed reducer. The reducer needs a certain condition, wherein the combination of the teeth of each gear needs to be specially arranged, and the specific reducer can be formed only by specifically determining the combination of the teeth of each gear. The invention provides a total of 110 gear tooth combinations, which can form a speed reducer with reduced abrasion in operation.

Defining Zz as the tooth number of a left sun gear, Xz as the tooth number of a left planet gear, Zy as the tooth number of a right sun gear and Xy as the tooth number of a right planet gear; when the planet carrier is connected with the input end, the right sun wheel is connected with the locking end, and the left sun wheel is connected with the output end, the transmission ratio of the speed reducer is a left transmission ratio Cz which is 1/(1- (Zy Xz/Zz Xy)); fig. 1 and 2 show such an input/output locked connection method. When the planet carrier is connected with the input end, the left sun gear is connected with the locking end, and the right sun gear is connected with the output end, the transmission ratio of the speed reducer is a right transmission ratio Cy which is-Cz + 1; fig. 3 and 4 show such a connection method of input/output lock. When the value of each transmission ratio is a positive value, the rotating speed of the input end is the same as the rotating speed of the output end in the direction; when the value is negative, the rotating speed of the input end is opposite to the rotating speed of the output end. And the gear tooth number combination of the gears is the numerical combination of the left sun gear tooth number Zz, the right sun gear tooth number Zy, the left planet gear tooth number Xz and the right planet gear tooth number Xy.

In the following table, in the combinations of the teeth of the gears, the numerical values of the right sun gear tooth number Zy are listed in the first row, the sixth row and the eleventh row, the numerical values of the left sun gear tooth number Zz are listed in the second row, the seventh row and the twelfth row, the numerical values of the left planet gear tooth number Xz are listed in the third row, the eighth row and the thirteenth row, and the numerical values of the right planet gear tooth number Xy are listed in the fourth row, the ninth row and the fourteenth row; the values of the left gear ratio Cz are listed in the fifth, tenth and fifteenth columns. In each row, the values in the first, second, third and fourth columns make up a set of combinations of the teeth of the gears, the fifth column being the value of its corresponding left gear ratio; the numerical values in the sixth, seventh, eighth and ninth columns form a set of combinations of the teeth of the gears, and the tenth column is the value of the corresponding left transmission ratio; the values in the eleventh, twelfth, thirteenth and fourteenth rows make up a set of combinations of the teeth of the gears, and the fifteenth row is the value of its corresponding left gear ratio. Each value for the corresponding right gear ratio can be derived from the value for the left gear ratio and is not listed in the table. The gear tooth array combination and the corresponding left transmission ratio of 110 gears are shown as the following table I:
