Technical field
The utility model relates to the mechanical transmission technical field, is specifically related to a kind of rubber and plastics machine special reduction gear.
Background technique
The speed reducer structure generally comprises decelerating casing, is installed in input, output shaft in the decelerating casing, and is installed in the driving gear on input, the output shaft; Driving gear through having velocity ratio on input, the output shaft is realized subduing of outputting power, because the engagement driving of gear in housing just need be added Lubricants in housing; Reduce friction loss; Owing to for the ease of observing the gear engagement situation in the housing, on housing, open viewport simultaneously, thereby the particle dust of outside gets in the housing from viewport easily; Receive the extruding of gear behind the particle dust entering housing; Can cause gear to produce certain wearing and tearing, shorten the working life of driving gear, the working life of also just having reduced speed reducer.
Summary of the invention
To above-mentioned technical problem; The utility model provides a kind of rubber and plastics machine special reduction gear; Its gearing down is firm; Outside particle dust can not get in the speed reducer, the loss of having avoided particle dust that the friction of driving gear is caused, thus prolonged working life of driving gear and speed reducer.
The technological scheme that realizes the utility model is following:
A kind of rubber and plastics machine special reduction gear; Comprise upper box, be installed in the lower box that upper box below and upper box are combined into reducer shell; In the reducer shell that is combined into, driving mechanism is installed; Said driving mechanism comprises power input shaft, intermediate propeller shaft, the pto that is arranged on the lower box; And be fixedly installed on main transmission tooth on the power input shaft, be fixedly installed on the intermediate drive gear that is meshed with the main transmission tooth on the intermediate propeller shaft and be fixedly installed on the output drive gear on the pto; On intermediate propeller shaft, also be provided with the driving cog that is meshed with output drive gear, said main transmission tooth and power input shaft are for being wholely set, and driving cog and intermediate propeller shaft are for being wholely set;
On upper box, offer the viewport window, on the viewport window, air-strainer is installed, and the viewport window is carried out the sealing cover of capping.The air-strainer effect is exactly to prevent that dusts such as outside particle, dust from getting in the speed reducer through the viewport window, the wearing and tearing that the driving cog of its inside is produced, thus also just prolonged working life of driving gear.
The two end part of said power input shaft, pto are arranged on the lower box through spheric roller bearing respectively, and the two end part of intermediate propeller shaft are arranged on the lower box through tapered roller bearing.
Casing is provided with the end cover that bearing is sealed, and end cover seals bearing, has also stoped the Lubricants seepage in the decelerating casing to be gone out simultaneously.
Intermediate propeller shaft is provided with middle driving gear is carried out the first spacing distance ring, and pto is provided with output drive gear is carried out the second spacing distance ring.Distance ring has guaranteed that driving gear can not produce and has moved axially, thereby guaranteed its stability of transmission ability.
Adopted such scheme, main transmission tooth and power input shaft be for being wholely set, and driving cog and intermediate propeller shaft be for being wholely set, thereby guaranteed the steadiness of transmission; On the viewport window, air-strainer is installed in addition, has been prevented that effectively dusts such as outside particle, dust from getting in the speed reducer through the viewport window, the wearing and tearing that the driving cog of its inside is produced, thus also just prolonged working life of driving gear and speed reducer.
