Background technology
Have some farm machineries to adopt chain drive, like tractor, rotovator, the chain drive case is the key position of power transmission, but also is weak position.It uses and opens and inspect all cumbersome, and fault rate is high.As: its requirement must be adjusted strainer at every turn when opening and inspecting, make the chain slack list have certain tensile force, prevents the sagging and crowded broken casing in chain elongation back; In opening and inspecting process, also answer the part of each chain link of scrutiny chain in addition, damage, ftracture like the chain sheet as finding chain part; Phenomenons such as roller breaks though this moment, chain was not disconnected, also should change part of damage immediately; And the taking-up breaker element, in order to avoid cause bigger damage; Tractor is when carrying out the rotary tillage operation in addition; Cross ridge, field ditch should be mentioned rotovator; Should be slowly when putting down, otherwise can make the chain load that is hit produce fracture because of tractor adds heavy load suddenly, in case the chain fracture; Because inertia and the damage of pushing the sprocket and the transmission case body that very easily cause the main shaft driving gear cause economic loss and miss the farming season to the user.And adopt the chain cost high, annual or will change in 2 years because of chain, price is high, the expense that also needs repairing.Replaced the chain drive case though gear (for example flat gear transmission case) on market, also occurred; But this gear price is high; It is bigger that casing is processed error through casting, can cause gear to put to enter or put in because of excesssive gap play back and forth, and transmission accuracy is low.
Summary of the invention
In order to address the above problem, the utility model provides a kind of transmission case of agricultural machine, and this transmission case intensity is big, and transmission accuracy is high, and the life-span is long, and efficiency of assembling is high, and cost performance is high.
For realizing above-mentioned purpose, the concrete scheme of the utility model is:
A kind of transmission case of agricultural machine comprises supporting seat, cover plate, power shaft, output shaft, power transmission shaft, and said cover plate is fixedly connected and forms a cavity with supporting seat; Said power transmission shaft is positioned at cavity, and power transmission shaft is fixed in supporting seat and cover plate by a holder at least, and said power transmission shaft relative fixed seat is rotatable; Two ends at said power transmission shaft have bevel gear respectively; One end of said power shaft passes cover plate and is positioned at cavity, and an end that is positioned at cavity at said power shaft is equipped with input bevel gear, and this input bevel gear is meshed with the bevel gear of power transmission shaft one end; The other end of said power shaft is positioned at outside the cavity; One end of said output shaft is positioned at cavity, and an end that is positioned at cavity at said output shaft is equipped with output bevel gear, and this output bevel gear is meshed with the bevel gear of the power transmission shaft other end; The other end of said output shaft is positioned at outside the cavity, and said power transmission shaft is vertical with power shaft, output shaft respectively.
A kind of embodiment is that an end of said output shaft passes supporting seat and is positioned at cavity; An end that is positioned at cavity at said output shaft is equipped with output bevel gear; This output bevel gear is meshed with the bevel gear of the power transmission shaft other end, and the other end of said output shaft is positioned at outside the cavity.
The end that another kind of embodiment is said output shaft passes cover plate and is positioned at cavity; An end that is positioned at cavity at said output shaft is equipped with output bevel gear; This output bevel gear is meshed with the bevel gear of the power transmission shaft other end, and the other end of said output shaft is positioned at outside the cavity.
Preferred construction: said power transmission shaft is fixed in supporting seat and cover plate by two holders.
Said power transmission shaft passes through bearings on holder.
Said power shaft, output shaft pass through bearings respectively in cover plate and supporting seat.
The other end that is positioned at outside the cavity at said power shaft has spline.
The other end that is positioned at outside the cavity at said output shaft has gear.
The other end that is positioned at outside the cavity at said output shaft has spline.
The advantage of the utility model is following: because the spoilage of gear is far below chain, and power transmission shaft also makes the intensity of transmission case body strengthened through the fixing of bearing block; Transmission accuracy is high; The transmission life-span is long, and cost is low; Practice thrift installation time, improve efficiency of assembling; Cost performance is high.
