Embodiment Construction
[0024] Referring to the accompanying drawings, specific embodiments of the present invention will be described in detail.
[0025] see Figure 1 to Figure 2, an embodiment of a high-torque planetary gear reducer for a generator, a high-torque planetary gear reducer for a generator, including a housing 1, which supports an input shaft 7 and an output shaft 9, and the input shaft 7 and the output shaft 9 are located on the same axis line, and the two shafts are not connected. One end of the input shaft 7 protruding is used to connect the power source, and the other end of the input shaft 7 is circumferentially fixed with an inner ring gear disc 4, so The end of the input shaft 7 can be provided with a spline, and the input shaft 7 is connected to the ring gear disc 4 through a spline. The connection structure of the spline is relatively uniform in force, the stress concentration at the tooth root is small, and the shaft strength is relatively weak. Less, more teeth, larger tota...

The invention relates to a large-torque planetary line speed reducer for a generator. The large-torque planetary line speed reducer comprises a shell, and an input shaft and an output shaft are supported in the shell, and are not connected to each other; one end, extending outward, of the input shaft is used for connecting a power source, and an inner gear ring disk is fixed to the other end of the input shaft circumferentially; an inner gear of the inner gear ring disk is engaged with a planetary gear supported on a planetary carrier, and the planetary gear is engaged with a sun gear which isprovided with a fixed disk of which the diameter is larger than the diameter of the sun gear; a bolt hole formed in the shell is a stepped hole of which the minor diameter segment is a threaded hole,and the interior of the major diameter segment of the stepped hole is matched with a hollow cylindrical pin of which one end extends out of the stepped hole; the hollow cylindrical pin penetrates thebolt through hole of the fixed disk, and is in clearance fit to the bolt through hole of the fixed disk; a stop bolt penetrates a hollow inner hole of the hollow cylindrical pin, and is threaded connection with the minor diameter segment, and the hollow cylindrical pin is pressed into the stepped hole; and the output shaft penetrates the inner hole formed in the sun gear, and supported in a bearing block hole formed in the shell through a bearing.
Description
technical field [0001] The invention relates to a reducer, in particular to a high-torque planetary gear reducer for a generator. Background technique [0002] Since the generator industry requires an output speed of 1500rpm, and in order to ensure that the generator can run in the high-efficiency zone for a long time, it is now necessary to decelerate and increase the torque of the power device with a maximum power of 1800KW and an output torque of 10000Nm through a planetary reducer to ensure the efficiency of the generator. There is no need to lower the speed and sacrifice efficiency to meet the industry's 1500rpm requirements. The reason why the planetary reducer has the advantages of small size, light weight, and high load-carrying capacity is mainly due to the fact that multiple planetary gears are used to share the load on average to form a power split. And the internal meshing can be reasonably used, so the load distribution among the planetary gears is balanced. If ...
