Gearbox with lubrication circuit

Abstract

The invention discloses a speed reducer with a lubricating loop. The speed reducer comprises a shell, a cycloidal gear, a transmission plate, an input shaft and an output module, wherein inner teeth are annularly arranged in the shell; the cycloidal gear is arranged on the outer peripheral surface of the shell, and is provided with outer teeth; the outer teeth are engaged with the inner teeth; thecycloidal gear is provided with a first accommodating tank and a first hole; the transmission plate is projected on first and second convex parts; the first convex part is arranged in the first accommodating tank; the transmission plate is provided with a second hole; the input shaft is inserted in the first hole and the second hole, and is provided with an eccentric part sleeved in the first hole; the output module is pivoted in the shell, is provided with a second accommodating tank for accommodating the second convex part, and is provided with first and second reflux channels; the first reflux channel communicates with the second accommodating tank; and the second reflux channel communicates with the first reflux channel, so that lubricating oil is extruded to flow into the second reflux channel and flow back into the first reflux channel, and flowing of the lubricating oil is enhanced to lubricate speed reducing mechanism pieces and to reduce accumulation of the lubricating oil.

Description

technical field [0001] The present invention relates to a cycloid reducer, in particular to a reducer with a lubricating circuit. Background technique [0002] With the booming demand for automation, the importance of the robotics industry is also increasing day by day. The urgency of the lubrication problem required by the reducer, which plays an important role in the robot industry, is also relatively high. The reducer is a power device that uses gear configuration to achieve lower output speed than input speed and higher output torque than input torque. Known as US Patent No. 8403789B2 is a deceleration mechanism, which uses a combination of a cycloidal drive and an Oldham shaft coupling to achieve deceleration and bilateral output. Another example is Japanese Patent No. 2011-64219A, which also discloses a cycloidal speed reduction device, which also achieves a speed reduction effect. However, none of the aforementioned prior art has any design for the lubricating stru...

Problems solved by technology

However, none of the aforementioned prior art has any design for the lubricating structure. After a long period of operation, the lubricating oil filled in the reduction mechanism tends to accumulate in some gaps, which reduces the lubricating effect between the components.
