Compared with the prior art, the gearbox has the advantages of small size, light weight, compact layout structure, aesthetic appearance, reliability, high precision, low cost and high performance, and meeting high-speed boats, yachts conditions and user requirements.
Description
Technical field
The utility model relates to the clutch equipment of a kind of, clutch suitable, deceleration, be applicable to self-propelled vehicle, boats and ships transferring power usefulness, be particularly useful for speedboat and inland river, coastal various boats and ships by having of fluid control.The driving device that belongs to the ship power propulsion system.
Background technology
The existing cooresponding marine gear box of power, as 120C type ship gear case, it includes input shaft parts, transmission shaft parts and output shaft assembly, three axle systems all are supported on the casing by conical bearing, the adjust the clearance of bearing is had relatively high expectations, it is improper to adjust, promptly too tight or too loose, all can cause the serious quality accident such as eccentric wear, bearing sintering of oil sealing cover and oil seal ring; Simultaneously the lubricated of bearing all adopts lubrication by atomization, and when driving engine began to start, because rotating speed is lower, there were unlubricated state in input shaft and transmission shaft bonnet bearing that the position is in the casing upper end, and the axle orange burns out in the platform position or during user's test run.Oil pump passes in and out oily interface and is external steel pipe, connects with track bolt, and because of the gear case volume is little, location gap causes the tube bending radius little for a short time, influences pipeline drift diameter, easily produces bending crack, welds difficulty and generation seepage phenomenon.Because the power-transfer clutch postposition, dynamical axis will bear the bending force action simultaneously, has reduced transmission capacity; Input shaft power transmits by the axle sleeve spline, and supporting also is supported on the casing by shaft room ground connection, is difficult for guaranteeing precision, and input end bearing failure situation often takes place.All above-mentioned phenomenons all exert an influence to small-sized, light-duty marine gear box quality.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of volume littler, weight is lighter, simple for structure, arrange compact, good looking appearance, good reliability, the precision height, the light high-speed marine gear box that cost performance is high, it includes casing, the input shaft parts, transmission shaft parts and output shaft assembly, described input shaft and transmission shaft are supported on the casing with cylinder tilting bearing and cylindrical roller bearing respectively, and output shaft is placed on the casing by a pair of tapered roller bearing, have hydraulic actuated parts to be installed on the rear side housing of input shaft, and oil pump is installed on the rear side housing of transmission shaft, oil pump and rear side housing faying face are provided with conducting turnover oil duct.
Each hot jacket of the front end of described input shaft and transmission shaft has to input drive gear that clutch outer member is arranged and transmission transmission gear, input clutch and drive clutch are arranged in the transmission gear, be respectively arranged with clutch plunger on two power-transfer clutchs, one side of piston is communicated with oil pocket in the hydraulic pressure, and another side is provided with return spring.
The utility model compared with prior art has characteristics such as volume is little, in light weight, structural arrangement is compact, good looking appearance, good reliability, precision height, cost performance height, can meet high speed piece ship, yacht operating mode, satisfies customer requirements.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a transmission shaft block construction scheme drawing of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: the utility model mainly includes casing, input shaft parts, transmission shaft parts and output shaft assembly.On casing 1, input shaft 4 is installed by a pair of cylinder tilting bearing 2 and cylindrical roller bearing 3, the one end links by input coupler and power, front end hot jacket on the input shaft has the input drive gear 5 that has clutch outer member, other end sliding sleeve has input driving gear 6, and the centre is lined with plain bearing 7.Input drive gear 5 is meshed with the transmission transmission gear 8 that has clutch outer member of hot jacket on transmission shaft, transmission shaft 9 is installed on the casing 1 by a pair of cylinder tilting bearing 2 and cylindrical roller bearing 3, the other end of transmission shaft 9 also sliding sleeve has transmission gear 10, the centre is lined with plain bearing 7, and input driving gear 6 and transmission gear 10 mesh with the driven gear 12 of hot jacket at output shaft 11 respectively; Output shaft is placed on the casing by a pair of tapered roller bearing 13, and this output shaft 11 links to each other with tailing axle by plunging joint 25.Input driving gear 6 and transmission gear 10 connect with input drive gear 5 and transmission transmission gear 8 respectively by hydraulic actuated Wet-type multi-disc friction clutch 14,15 separately, be respectively arranged with clutch plunger 16,17 on the power-transfer clutch 14,15, one side of piston is communicated with oil pocket 18,19 in the hydraulic pressure, and another side is provided with return spring 20,21.Hydraulic operation parts 22 are installed on the rear side housing of described input shaft 4, and oil pump is installed on the rear side housing 23 of transmission shaft 9, this oil pump and rear side housing faying face are provided with conducting turnover oil duct, and communicate with oil filter 24 and oil sump respectively.During use, when bar handle " stopping " position, promptly cut off the power fluid of the power-transfer clutch 14,15 on input shaft 4 and the transmission shaft 9 simultaneously, switch to back oil road, clutch plunger 16,19 hightails friction lining under the effect of return spring 20,21, input driving gear 6 and transmission gear 10 sky respectively are enclosed within on input shaft 4 and the transmission shaft 9, thereby, can not drive the driven gear 12 of hot jacket on output shaft 11 and rotate, propeller stops not change.At this moment, the oil in the hydraulic efficiency pressure system all is lubricating oil, by each oil duct each lubricating point to the gear picture.When bar handle in " ahead running " position, the work oil duct conducting of the power-transfer clutch 14 of input shaft 4, operating oil pressure promotes clutch plunger 16 pressing friction sheets, input driving gear 6 is rotated synchronously with input shaft, and drive driven gear 12 backward rotation, at this moment, boats and ships advance.When bar handle in " reversing " position, the work oil duct conducting of the power-transfer clutch 15 of transmission shaft 9, operating oil pressure promotes clutch plunger 19 pressing friction sheets, transmission gear 10 and transmission shaft are rotated synchronously, and drive driven gear 12 backward rotation, at this moment, boats and ships retreat.
