Description
Technical Field
The utility model belongs to the technical field of the harmonic speed reducer machine is made, concretely relates to harmonic speed reducer machine oil blanket.
Background
The harmonic speed reducer is mainly composed of four basic components of a wave generator, a flexible gear, a flexible bearing and a rigid gear, and is a gear transmission which is formed by assembling the flexible bearing on the wave generator to enable the flexible gear to generate controllable elastic deformation and is meshed with the rigid gear to transmit motion and power. The harmonic speed reducer has the advantages of high bearing capacity, large transmission ratio, small volume, light weight, high transmission efficiency, long efficiency, stable transmission, no impact, no noise, high motion precision and the like. Compared with other similar devices, the harmonic reducer has obvious advantages, but due to the structural reason of the harmonic reducer, the mounting space of the oil seal is very narrow. The output end of the harmonic reducer repeatedly swings in a crossed mode, the rotating speed is lower than 0-200rpm/min, the sealing medium is usually lubricating grease, and after the lubricating grease is filled in the closed cavity, higher friction temperature than that of the lubricating grease is easily caused, and internal pressure is formed. Meanwhile, the rotation speed and the sealing medium cannot form a pumping effect, so that oil leakage of the oil seal is caused, and the use of the whole robot is influenced. Based on the above reason, the utility model discloses hope to provide a harmonic speed reducer machine's oil blanket.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution of a harmonic reducer oil seal:
the utility model provides a harmonic speed reducer machine oil blanket, includes annular skeleton 1, and the outer lane of annular skeleton 1 is equipped with outer lane rubber layer 2, and the design on outer lane rubber layer 2 not only can increase the frictional force when installing the oil blanket, and can reduce the vibrations in small, broken bits in the harmonic speed reducer machine course of operation. The annular framework 1 is provided with a sealing ring fixing ring 3, the sealing ring fixing ring 3 is provided with a sealing ring main body 4, and the inner ring of the sealing ring main body 4 is provided with a main sealing lip 5 and a dust lip 6. Dustproof lip 6 is the outside setting to one side, and the outside setting to one side can make it produce the power that compresses tightly the transmission shaft, reduces the invasion of dust in the high dirt environment greatly. The cross-section of main seal lip 5 is triangle-shaped, and this setting can reduce the friction between main seal lip 5 and the transmission shaft under the prerequisite of guaranteeing the transmission shaft stability, prolongs main seal lip 5's life. Four parallel grooves 7 are provided in the lip of the main seal lip 5, grease 8 is provided between the main seal lip 5 and the dust lip 6, and similarly, grease 8 is provided in the four parallel grooves 7. The four parallel grooves 7 are arranged, so that lubricating grease 7 can be locked, and the lip tip part is lubricated; compared with the main seal lip 5 without the parallel grooves, the parallel grooves 7 can distribute the lubricating grease 8 on the contact surface of the main seal lip 5 and the transmission shaft more uniformly, and along with the rotation of the transmission shaft, the lubricating grease 8 in two adjacent parallel grooves 7 can realize slow exchange, so that the same lubricating effect is achieved, and the using amount of the lubricating grease 8 is less.
