Abstract
The utility model discloses a speed reducer dedicated to asphalt mixing which comprises a motor and a reduction gear box, wherein four stages of reducing mechanisms and a synchronous gear mechanism are arranged in the reduction gear box, and the speed reducer dedicated to asphalt mixing is characterized in that the transmission gear of a primary reducing mechanism adopts a spiral bevel gear, the transmission gears of secondary, tertiary and quaternary reducing mechanisms adopt bevel wheels, and the primary reducing mechanism is meshed with the synchronous gear mechanism. In order to solve the problem that damages to the spiral bevel gears are caused since the forced directions of spiral bevel gears of two conventional speed reducers are opposite, and the transmission gear of the primary reducing mechanism adopts the spiral bevel gear having a left spiral or right spiral structure. When the speed reducer dedicated to asphalt mixing is used on a blender, the two speed reducers of which the directions of spiral are opposite are adopted, the condition of opposite forced directions can be avoided, the axial load of a bearing is reduced, and the service life of the complete machine is prolonged. The utility model has the advantages of compact structure, small volume, high transmission accuracy and strong bearing capacity.
Description
Technical field
The utility model belongs to the speed reducer technical field, particularly a kind of stirring special reduction gear.
Background technique
Along with the development of modern industrial technology, all trades and professions are more and more higher to the requirement of speed reducer, and especially to the special reduction gear in the industry, and the index request of aspects such as volume and bearing capacity is strict more.At present, also depend on import for pitch stirs the supporting special reduction gear great majority of industry, the producer of domestic production is very few.At present, in the various speed reducers of known at home stirring industry special use, the demand that this pitch is stirred speed reducer is still very big.But at present, structurally have very big shortcoming for this speed reducer, its shortcoming is: the input end left and right sides rotation direction at it is not separated, can cause its spiral bevel gear to be subjected to force direction opposite, finally causes the damage of spiral bevel gear.
Summary of the invention
The utility model provides a kind of compact structure for solving the technical problem that exists in the known technology, and volume is little, transmission accuracy height, the stirring special reduction gear that bearing capacity is strong.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of pitch stirs special reduction gear, comprise motor, speed reducer, be provided with level Four reducing gear and synchromesh gear mechanism in the speed reducer, it is characterized in that: the driving gear of described first class reducer structure adopts spiral bevel gear, described secondary, three grades, the driving gear of level Four reducing gear adopt helical gear, described first class reducer structure engagement synchromesh gear mechanism.
The utility model can also adopt following technological scheme:
The driving gear of described first class reducer structure adopts the spiral bevel gear of left-handed or dextrorotation structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly adopt the level Four reducing gear, wherein the first class reducer structure adopts the spiral bevel gear transmission, secondary, three grades, the transmission of level Four reducing gear employing helical gear, be fitted with synchromesh gear mechanism simultaneously, do not changing the function that synchronous output is provided under the situation that increases volume like this, thereby it is little to have solved volume, compact structure, solved speed reducer heaviness, bulky problem with synchronous output shaft.When practical application, general speed reducer occurs in pairs, adopts two opposite speed reducers of above-mentioned Hand of spiral, can avoid stressed opposite situation, the axial load that has alleviated bearing, the life-span of having improved complete machine.
