Abstract
The utility model discloses a heat radiating device of a speed reducer, which comprises a worm gear of the speed reducer, and a shell body of the worm gear. The heat radiating device is characterized in that the worm gear is axially provided with a cooling fluid hole channel, and a cooling fluid inlet pipe and a cooling fluid outlet pipe are communicated with the cooling fluid hole channel of the worm gear. According to the working characteristics of the worm gear, a cooling water hole channel is arranged on the worm gear, and flowing water can timely take away friction heat, so as to not only be beneficial for the power exerting of the speed reducer, but also lower the requirements of the worm gear for manufacturing materials (the worm gear can be manufactured by ferrous metal materials), reduce the manufacturing cost, and save precious metal.
Description
Technical field:
The utility model relates to speed reducer, is specifically related to the sink of speed reducer.
Background technique:
At present, the worm and gear of speed reducer is in transmission process, the frictional heat that produces is lubricated by lubricant oil and heat is taken away, because worm and gear is provided with housing, therefore, the heat that lubricant oil is taken away can only distribute in housing, by housing again to around the heat radiation, such radiating mode efficient is very low, especially always be in the worm screw in running up, its working surface is being worked all the time, rubbing, generating heat, though above-mentioned cooling measure is arranged, in general the operating temperature of worm screw is still about 70 degree, not only influence the power performance of worm reduction gear, and working life, and in order to guarantee the safe in utilization of equipment, worm and gear can only adopt comparatively expensive tin bronze material, strengthened the manufacture cost of worm reduction gear, and user's acquisition cost.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of sink of speed reducer, directly takes heat out of housing, and the radiating efficiency height can reduce worm and gear greatly to making the requirement of material.
The utility model is achieved through the following technical solutions:
The sink of speed reducer comprises the worm and gear of speed reducer and the housing of worm and gear, and characteristics are that worm shaft is to being provided with the cooling liquid duct, into and out of the cooling liquid hole link of coolant pipe and worm screw.
Be communicated with by the sliding sealing device that is arranged on the worm screw with the duct into and out of coolant pipe, the cooling liquid in described duct is advanced or is exported on the worm screw that is arranged at the wrom tooth two ends, or cooling liquid advances or exports on the worm screw that is arranged at wrom tooth one end, and another cooling liquid is advanced or exported the worm screw termination that is arranged at the wrom tooth the other end; Described cooling liquid is advanced or exports to be positioned at sliding sealing device, and described sliding sealing device is connected and fixed on housing by set connection pawl.
Being positioned at the sliding sealing device on the wrom tooth one end worm screw, is the casing that a two ends end cap is provided with through hole, and worm screw passes the through hole that tank ends covers, and box body wall is provided with the connecting port that cooling liquid is advanced or gone out, and advances or goes out coolant pipe and be connected with connecting port; At least be provided with a circular groove on the circumferential surface of described through hole, be provided with seal ring in the circular groove.
Be positioned at the sliding sealing device of worm screw termination, it is the drum that an end is provided with the end, the drum muzzle is in the worm screw end, at least be provided with a circular groove on the drum mouth internal face, be provided with seal ring in the circular groove, the bucket end, be provided with the connecting port that cooling liquid is advanced or gone out, and advances or go out coolant pipe and be connected with connecting port.
The described the other end into and out of coolant pipe is communicated with running water pipe, sewer respectively, or is communicated with the water pump entery and delivery port respectively.Described cooling liquid can be water, pressurized air, refrigeration agent.
The utility model is according to the worm and gear work characteristics, the cooling water duct is set on worm screw, the water that flows is in time taken away frictional heat, not only help the power performance of speed reducer, and reduced the requirement (can make) of worm and gear Manufacturing material of ferrous material, reduce manufacture cost, saved noble metal simultaneously.
