Abstract
The utility model provides a motor shaft, which comprises a first connecting rod, a first polish rod, a knurling rod, a second polish rod, a third polish rod, a fourth polish rod and a second connecting rod which are connected in sequence, wherein the first connecting rod is provided with an annular trough; the first connecting rod is divided into a first section and a second section by the annular trough; the first section is provided with left-hand threads; the knurling rod is provided with a knurl; and the second connecting rod is provided with left-hand threads. According to the motor shaft disclosed by the utility model, the traditional right-hand threads is replaced by the left-hand threads; in the motor shaft rotation process, two ends can be fastened closer and closer to avoid loosening due to long-time operation; the third polish rod and the fourth polish rod are in slope transition to lower stress concentration, bring convenience in processing and improve the integral strength; and the annular trough is used for clamping a snap spring to finish axial positioning and installing, thus being convenient to assemble and disassemble.
Description
Technical field
The utility model relates to a kind of axle, particularly a kind of motor shaft.
Background technique
