Embodiment Construction
[0010] Such as figure 2 As shown, the planetary reducer for reducing transmission friction and heating includes a sun gear 1, an end cover 4 located at one end of the sun gear 1, and a limit steel ball 3 is clamped on the inner end surface of the end cover 4; the limit steel ball 3 protrudes from the end The inner surface of the cover is in contact with the end surface of the sun gear 1; the center of the limiting steel ball 3 is located on the axis of the sun gear 1.
[0011] When the sun gear 1 and the limit steel ball 3 move relative to each other, since the sun gear 1 and the limit steel ball 3 are in point contact instead of surface contact, there is less heat generated by friction during the relative operation. The temperature rise of the reducer is low.
[0012] The rest of the technology is the same as the existing technology.

The invention relates to a planetary speed reducer capable of reducing transmission friction heating. The planetary speed reducer comprises a sun wheel and an end cover which is positioned at one end of the sun wheel. The planetary speed reducer is characterized in that a limit steel ball is clamped on the inner end surface of the end cover; the limit steel ball protrudes out of the inner surface of the end cover and contacts the end surface of the sun wheel; and the ball center of the limit steel ball is positioned on the axis of the sun wheel. The planetary speed reducer generates less heat in the operation process, the problem that the speed reducer can not rotate normally because of component sintering when the speed reducer generates over-high heat in the operation process is solved; and the speed reducer has simple structure and is easy to manufacture and produce.
Description
Technical field [0001] The invention relates to the technical field of speed reducers, especially planetary speed reducers. Background technique [0002] The devices currently applied to the axial positioning of the sun gear on the planetary reducer all adopt such figure 1 As shown in the figure, the axial displacement of the sun gear 1 is restricted by the limit pad 2. Due to the surface contact between the sun gear and the limit pad, when the contact surfaces of the two parts are running at relatively high speed, the friction generates more heat. The lighter one will cause the reducer to heat up, and the heavy one will cause overheating due to friction, causing the sun wheel 1 And the limit pad 2 is sintered, so that the reducer cannot be operated. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a planetary reducer that reduces transmission friction heating, which genera...
