Abstract
A hydraulic speed increasing gear box comprises an input shaft supported in a box body through a bearing and is characterized in that an input gear is fixed on the input shaft and engaged with a driven gear which is sleeved on an output shaft and combined with a clutch base; the clutch base, a clutch housing on the output shaft, an inner friction plate, an outer friction plate and a piston constitutes a clutch; the clutch housing is fixedly arranged on the output shaft which is supported on the box body through a bearing; the input shaft is further fixedly provided with an oil pump gear which is engaged with an oil pump driven gear; the oil pump driven gear is connected with an oil pump; due to the fact that the clutch is arranged on the output shaft with a very high rotating speed, and the torque of the clutch is very small; and in the power transmission process, the clutch can be manufactured to be very small, thereby achieving the requirements of compact structure and high efficiency.
Description
Technical field
The utility model relates to a kind of hydraulic control that has, speedup output, but clutch, the gear-box of speedup belongs to the power transmission technology field.
Background technique
Existing advanced gear-box is paid by input shaft, output shaft, clutch and relevant meshed gears and is formed, and it has the function of clutch, deceleration or speedup.Be not arranged on the output shaft but still there is the clutch of making at present,, make the volume of clutch and capacity obtain minimum because of the reason of speedup.So existing said gear case, its weight is heavier, and volume is bigger.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that existing technology exists, and provides a kind of simple in structure, and is in light weight, can make the hydraulic pressure step-up gear of the minimum that transmission device does by working condition requirement.
The purpose of the utility model is accomplished through following technological scheme; It comprises one through the input shaft of bearings in casing; It is characterized in that being fixed with on the described input shaft input gear, described input gear and is nested with on output shaft and with the conjuncted driven gear of a clutch base and is meshed; Clutch outer member on described clutch base and the output shaft and interior outside friction disc and piston are formed a clutch, and said clutch outer member is packed on the output shaft, and output shaft is bearing on the casing through bearing.
Also be fixed with oil pump gear on the described input shaft, this oil pump gear is meshed with oil pump driven gear, and oil pump driven gear links to each other with oil pump.
On the described input shaft input coupling is housed, the bearings of passing through two symmetric arrangement on the input shaft is on casing.
The utility model is to be arranged in clutch on the high speed shaft, is installed in the required oil pump of gear-box hydraulic system on the input shaft, promptly often changes on the lower velocity shaft, makes the requirement of satisfying whole system.And handiness, flexible, safe and reliable.
This gearbox input shaft is a lower velocity shaft, and the oil pump drive gear of a speedup gearwheel and the work of a drive oil pump is housed on the lower velocity shaft, drives oil pump work when input shaft is rotated, and the driven gear that drives simultaneously on the output shaft rotates.
Driven gear and hydraulic coupling are housed on the output shaft, and an end of driven gear is equipped with clutch base, and interior friction plate is housed on the clutch base, and the endoporus of driven gear is equipped with bearing, can with output shaft to rotating.Be fixed with clutch outer member on the output shaft, outside friction disc is arranged in the shell, when clutch is not worked; Output shaft does not rotate, when clutch is worked, because the interior outside friction disc in the clutch engages; The driving torque that makes driven gear is through clutch base on it and interior friction plate; Outside friction disc, clutch outer member are delivered on the output shaft, and output shaft is rotated.Pass power.
The utility model is accomplished institute's bringing onto load like (propeller cavitation), hydraulic jet propulsion, water pump, the work of oil pump etc. through the joint and the disengagement of clutch.Because clutch is arranged on the very high output shaft of rotating speed, the moment of torsion of clutch is very little, and in transmitted power, it is very little that clutch can be done, and reaches compact structure, the requirement that efficient is high.
Description of drawings
Fig. 1 is the structural representation of model utility.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in Figure 1; The utility model comprises one through the input shaft 2 of bearings in casing; Be fixed with input gear 4 on the described input shaft 2, described input gear and is nested with on output shaft and with the conjuncted driven gear 16 of a clutch base and is meshed; Clutch outer member on described clutch base and the output shaft 13 and interior outside friction disc and piston are formed a clutch 15, and said clutch outer member is packed on the output shaft 13, and output shaft is bearing on the casing through bearing 17,14.
Also be fixed with oil pump gear 5 on the described input shaft 2, this oil pump gear 5 is meshed with oil pump driven gear 7, and oil pump driven gear 7 links to each other with oil pump 9.Oil pump driven gear 7 is supported on the casing through bearing 6,8.
Embodiment: the utility model has an input shaft 2, and input coupling 1 is housed on the input shaft, is made up of the bearing 3,10 of two symmetric arrangement on the input shaft, and prop up on casing 11, and on input shaft, be fixed with input gear 4, and oil pump gear 5.Input gear on this input shaft is meshed with driven gear 16.Done clutch base on the driven gear 16, with clutch outer member and interior outside friction disc and piston composition clutch 15 on the output shaft 13, clutch outer member is packed on the output shaft 13, and output shaft is bearing on the casing by bearing 17,14.
When input shaft 2 rotated, oil pump gear 5 rotated, and drove oil pump driven gear 7 and rotated, and oil pump 9 is rotated, and guaranteed hydraulic work system, made the instruction of clutch executable operations.When input shaft 2 rotated, the input gear 4 on the input shaft drove driven gear 16 and rotates.Because driven gear 16 endoporus are equipped with bearing, this moment, driven gear can freely rotate and output shaft 13 does not rotate.When engaging under the operational order of clutch in hydraulic system, the clutch base of driven gear 16 on it, interior outside friction disc, the clutch 15 that clutch outer member is formed rotates output shaft 13, through output shaft coupling 12 power is exported again.
It is low that the utility model has solved input speed effectively, under the big condition of input torque, is installed in clutch on the output shaft of little moment of torsion, can guarantee the hydraulic system proper functioning simultaneously, realizes weight, and light volume is little, the effect that cost is low.
