Abstract
The invention relates to the mechanical field, and in particular relates to a speed reducer. The speed reducer comprises an oil blocking cover fixed inside a box body of the speed reducer, wherein the oil blocking cover surrounds the lower portion of a gear, a gap is arranged between the oil blocking cover and the gear, and the oil blocking cover is provided with an oil inlet channel. When the speed reducer is in a work state, the gear can bring lubricating oil in the oil blocking cover to a region of engagement to conduct lubrication in a rotating process, friction heat in the region of engagement of the gear is brought to an oil pool so that temperature of the region of engagement of the gear is lowered, and the lubricating oil on the outside of the oil blocking cover can flow in the oil blocking cover continuously through the oil inlet channel so as to supplement the lubricating oil in the oil blocking cover. Simultaneously, the gear stirs the lubricating oil inside the oil blocking cover in the rotating process; namely, corresponding work is done on the lubricating oil inside the oil blocking cover. Due to the fact that the lubricating oil inside the oil blocking cover is less; namely, the lubricating oil stirred by the gear is less, so that the work done by the gear on the lubricating oil is less, temperature rise of the lubricating oil is less, and thermal power of the speed reducer is improved.

Speed reducer is a kind of driving mechanism that utilizes driving component transferring power such as gear.Wherein the speed reducer driving component needs good lubricating, and most speed reducer driving component all adopts oil lubrication, and mostly its lubricating system is flooding system lubrication.With the gear is the example explanation; Flooding system lubrication is in a part of floodlubrication oil with gear, and during the gear revolution, sticking lubricant oil above that is brought to the meshing zone and is lubricated; Make to form oil film between two gear meshing flank of tooth, thereby reduce the life-span that friction improves gear; Also frictional heat is brought in the oil sump simultaneously, eliminates the frictional heat that gear is produced when transferring power, and then just make that the temperature of lubricant oil raises in the oil sump; Gear has also stirred the lubricant oil in the oil sump when rotating, and promptly the lubricant oil in the gear mesh oil sump has been done certain merit, thereby makes the temperature of the lubricant oil in the oil sump further raise; Lubricant oil in the oil sump is thrown on the inwall of speed reducer casing simultaneously, plays the effect of heat radiation through inwall.
Obviously, when adopting flooding system lubrication, in the casing of speed reducer enough lubricant oil should be arranged; Just can guarantee the needs that lubricate; But the degree of depth of gear floodlubrication oil is dark more, and gear is big more to the stirring degree of lubricant oil when rotating, i.e. gear mesh lubricant oil acting is many more; And then make that the temperature rising of lubricant oil is many more, that is to say that the thermal power of speed reducer is low more.
Because the temperature of lubricant oil is higher; When the mode through the cabinet wall heat radiation is not enough to satisfy the heat radiation of speed reducer lubricant oil; The temperature of lubricant oil continues higher, must make oil body reduction and lubricant oil also be easier to oxidation, and then reduce the life-span of lubricant oil; Increase the frequency of changing oil, thereby influenced the working life of speed reducer.
Therefore, how to reduce the temperature of lubricant oil, and then the thermal power of raising speed reducer is those skilled in the art's technical issues that need to address.
Summary of the invention
The purpose of this invention is to provide a kind of speed reducer, this speed reducer in use can be controlled the temperature of lubricant oil effectively, and then improves thermal power.
