Abstract
The utility model relates to a special gear box for mud pumps, which is mainly composed of a box body, an input shaft, a clutch, an output shaft, and a gear pair. One side of the output end of the box body is provided with a flange edge which is directly connected with a casing body of a mud pump. An impeller of the mud pump is connected to the output end part of the output shaft through trapezoidal threads. The output shaft is connected with the input shaft through a pair of shaft gear pairs. The input shaft is connected with a shaft gear arranged in the box body through the clutch. Thus, the utility model has the characteristics of small volume, light weight, simple structure, better use reliability, etc. Besides, the reliability of the whole transmission mechanism can be effectively increased.
Description
The utility model relates to a kind of device of gear transmission power, a kind of slurry pump dedicated transmission with clutch deceleration by hydraulic control.
Existing slurry pump driving mechanism mainly is made up of following each several part: the power diesel engine---air clutch---reduction gear box---cog-wheel coupling---slurry pump support and slurry pump.The above slurry pump driving mechanism of Gou Chenging, it is bulky, and weight is heavier, costs an arm and a leg; Especially air clutch and gear clutch in forming, their price is very high.Because volume is big, weight is big, and it is very big to make this mechanism that shared space is installed on dredger, correspondingly increased the weight and volume of whole ship, hindered the development of dredger, and used air clutch reliability is not high, makes the reliability decrease of whole driving mechanism to miniaturization.
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, and volume is little, and is in light weight, and price is low, the slurry pump special gear box of good reliability.
The purpose of this utility model is finished by following technical solution, it mainly is made up of casing, input shaft, clutch, output shaft and gear pair, output terminal one side at casing is provided with flange edge, it directly links to each other with the slurry pump housing, is connected with blade wheel of slurry pump in the output end of output shaft by trapezoidal thread.
Described output shaft is paid input shaft by a pair of shaftgear and is linked to each other, and input shaft is connected mutually with the shell of clutch, and the shaftgear that corresponding clutch base and kink are placed in the casing on input shaft, with bearing links by spline.
The utility model also is provided with speed governing relay or dynamic overload protector in the rear end of output shaft.
Description of drawings is as follows:
Fig. 1 is a drive mechanism schematic diagram of the present utility model.
Fig. 2 is a drive mechanism schematic representation of the present utility model.
Fig. 3 is that the side of Fig. 2 is shown structural representation.
Below in conjunction with accompanying drawing the utility model is described in detail: the utility model is mainly by input block, output block, and box part, controlling component is formed.
Input block comprises: bearing 1 and shaftgear 2, and by the clutch that friction plate 3, clutch base 4, clutch outer member 5 are formed, input shaft 6, bearing 7, bearing 19.Input shaft 6 is supported on bearing 7 and the bearing 19; Clutch outer member 5 and input shaft 6 interference fit joint; Kink is supported on the bearing 1 at the shaftgear on the input shaft 2; Clutch base 4 connects by spline and shaftgear 2.
Output block comprises: output shaft 8 and bearing 9,10,12, and with the output gear 16 of shaftgear 2 engagements, bearing 17.Be circumscribed with blade wheel of slurry pump by trapezoidal thread on the clutch end of output shaft 8; Bearing 12 is bearing the pulling force that blade wheel of slurry pump produces.
Box part comprises: upper box 20 and lower box 21 and speed governing relay 11, this speed governing relay also usable power diesel engine overload protection arrangement replace.The distolateral flange edge 22 that is provided with of the output shaft of described casing 20,21 the slurry pump housing with Bolt Connection on it.
Controlling component comprises: controller 13, and cooler 14, cooling unit 15 and oil pump 18, its structure is formed and is belonged to prior art.
Working procedure of the present utility model is as follows: the power of diesel engine is delivered to input shaft 6 through the input coupling, drives oil pump 18 work, and this oil pump 18 sucks working oil from casing 21, and it is sent to cooler 14, delivers to filter cleaner 15 again, delivers to controller 13 again.When controller 13 during in " stopping " position, it only produces lubricated each bearing of low pressure oil and clutch; When controller 13 during in " work " position, produce low pressure oil and high pressure oil, high pressure oil enters in clutch outer member 5 oil pockets by input shaft 6, promoting piston engages clutch outer member 5 and clutch base 4, drive shaftgear 2, drive output gear 16 again and rotate, drive output shaft 8 work again, because of being circumscribed with blade wheel of slurry pump by trapezoidal thread on this output shaft 8, so output shaft 8 directly drives blade wheel of slurry pump work.The other end at output shaft 8 also is connected with speed governing relay 11, and the rotation of output shaft 8 also drives its work simultaneously.
The utility model compared with prior art, it is little, in light weight, simple and reasonable to have a volume, makes Use good reliability, be conducive to dredger and develop to miniaturization, can Effective Raise whole transmission mechanism reliable The property, improve the characteristics such as the effective usable floor area of hull.
