The speed reducer is mainly made of cast iron, steel and the like. The cast iron material is a material commonly used in speed reducers, and has the advantages of low manufacturing cost, good machining performance, high compressive strength and the like. However, cast iron materials are inferior in wear resistance and corrosion resistance, and are prone to failure such as cracking and breaking. The steel material is also a material commonly used in speed reducers, and has the advantages of high strength, high hardness, good wear resistance, good corrosion resistance and the like. In addition, the steel material can be subjected to surface hardening treatment, so that the service life of the steel material is prolonged. However, the mass density of cast iron and steel materials is high.

In view of the above, the present invention aims to provide a high power density actuator speed reducer, which reduces the weight of the actuator speed reducer according to requirements and improves the power density of the speed reducer.
In order to achieve the above purpose, the present invention provides the following technical solutions: the high-power density actuator speed reducer comprises a box body, an output shaft and an output shaft, wherein the output shaft and the output shaft are arranged in the box body, and gears are arranged between the output shaft and the output shaft in a meshed manner; the input shaft and the output shaft are arranged in the box body through bearings, and the gears are all designed to be titanium alloy carburized gears.
Optionally, the box body is made of super-hard aluminum alloy material and is subjected to limit weight reduction design.
Optionally, bearings with sealing covers are arranged at the input end and the output end of the output shaft corresponding to the output shaft, so as to prevent grease from leaking and prevent impurities such as external dust, moisture and the like from entering the machine.
Optionally, the lubricating grease also comprises a wide-temperature extreme pressure lubricating grease 7254 arranged in the box body, wherein molybdenum disulfide components in the lubricating grease form an extreme pressure oil film inside the tooth surface of the speed reducer, so that the friction coefficient is reduced, the gear bearing is improved, the abrasion of parts such as gears and bearings is reduced, the cooling effect is also achieved, and the temperature in the machine is reduced.
The invention has the beneficial effects that: the invention changes the traditional steel gear into a titanium alloy carburized gear, the box body adopts a super-hard aluminum alloy material, the extreme weight reduction design is carried out, and the wide-temperature extreme pressure lubricating grease is adopted; the weight is reduced and the high power density is improved.
