Technical field
The utility model relates to gearbox, is specifically related to a kind of bevel gear drive gearbox.
Background technique
Gearbox is a kind of gear drive of high speed rotating; Gearbox mainly is made up of gear and transmission shaft; Gearbox has the following advantages: velocity ratio can change; Realize the change of velocity ratio through different gear meshing, thereby change the rotating speed and the torque of output shaft, can realize the output of different rotating speed and torque; Can change the sense of rotation of outputting power; Can realize the output and the interruption of power through the control of clutch.Because gearbox has above advantage, so gearbox mechanically is widely used various, realize the reducing or increase of transmission and rotating speed, torque of power, present used gearbox adopts spur gear, helical gear or planetary pinion transmission usually; Spur gear or helical gear gearbox are simple in structure, cost is low though adopt, and transmission efficiency is low, and power loss is big, and vibration and noise are big; Velocity ratio is little, if will obtain big velocity ratio, will increase the physical dimension of driving gear or transmission shaft usually; Thereby the physical dimension of gearbox is increased, the manufacture cost of gearbox is raise, adopt the gearbox of planetary pinion transmission; Transmission efficiency is higher, and power loss is little, and velocity ratio is big; But design loaded down with trivial details, complex structure, manufacture cost is high.
At present; The most complex structure of speed changer in the farm machinery that is applied in the tractor use adopts multistage power transmission, and manufacture cost is high; Bigger in the loss of power transmission process medium power; When gearbox is connected with the tractor rear power output shaft, need usually the tractor rear power output shaft to be linked to each other with the input shaft of speed changer through coupling, Placement is complicated.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and design provides a kind of gearbox, the bevel gear drive gearbox that simple in structure, low cost of manufacture, power loss are little, gearbox and tractor rear power output shaft can be connected fast.
For realizing above-mentioned purpose, the technological scheme of the utility model is a kind of bevel gear drive gearbox of design, and said gearbox comprises casing; On said casing, be provided with oil hole, be provided with end cap, it is characterized in that in the end of said casing; The other end at said casing is equipped with connecting sleeve, is provided with clutch shaft bearing at an end of said connecting sleeve and the inside of casing joint, in the endoporus of said clutch shaft bearing, is fixed with axle sleeve; Said axle sleeve is connected with large conical gear through mandrel; Said large conical gear and small conical gear are connected with a joggle, and said small conical gear is fixed on an end of transmission shaft, between the middle part of said transmission shaft and casing, are provided with spacer; Side at said casing is provided with bearing support; Be equipped with second bearing at the two ends of said bearing support, said second bearing fixing is in the ladder section of transmission shaft, is equipped with belt pulley at the side of said transmission shaft near the said second bearing place; Between said belt pulley and bearing support, be provided with seal ring, said belt pulley is fixed on the other end of transmission shaft through nut.
The advantage and the beneficial effect of the utility model are: in use; The tractor rear power output shaft is inserted in the connecting sleeve; The tractor rear power output shaft is stretched in the connecting sleeve; External splines on the tractor rear power output shaft is matched with the internal spline of connecting sleeve, gearbox is fixedly connected with tractor get final product through connecting sleeve then, Placement simply, connection is quick; The tractor rear power output shaft drives large conical gear and rotates, and large conical gear drives the small conical gear that is meshed with it and rotates, and small conical gear drives transmission shaft and rotates, the output of power, and simple in structure, fabricating cost is low; Owing to adopt and click the angular wheel transmission, changed the direction and the rotating speed of transmission of power, in the power transmission process, power loss is little.
