Abstract
The utility model discloses a gear box for an underwater dredge pump, which mainly comprises a left input component, a right input component, an output component, a box body and a pipeline component. The left input component and the right input component are mounted on the box body through bearings; an output gear of the output component is connected with an output shaft through solidification; and the output gear is integrally mounted on the box body through a bearing. The gear box for the underwater dredge pump is characterized in that the two input components and the output component are arranged in a horizontal different-center way; further, input ends and an output end are respectively positioned on opposite sides of the box body; and a sealing structure is arranged at the joint of the output component and the box body. The gear box disclosed by the utility model is integrally put in an underwater sealed cabin, and has an inclination angle which is approximately 60 degrees maximally in a working process; the output end is provided with the waterproof and oil-proof sealing structure; and by using the sealing structure, the sealing problem of the output end can be solved when the gear box is in an underwater and inclined working condition.
Description
Technical field
The utility model relates to a kind of gear drive of not exporting, slowing down, be applicable to the non-precession power delivery system of promoting mainly of boats and ships with clutch, double input list.
Background technique
Most in the market dredge pump mostly is a horizontal positioned with gear-box, but the gear-box that has need be installed on the crane span structure of boats and ships, integral body is with the skewed underwater of stretching into of crane span structure during work, when work, have the inclination angle, this time, the sealing configuration of conventional gear-box is for to be equipped with stuffing box packing at output terminal, and one O type circle is as getting rid of oil, when gear-box is in inclination operating mode following time, output terminal integral body is lower than the lubricant oil liquid level, be in floodage, packing seal can't reach seal action fully, and O type circle also can't realize getting rid of oily effect.
In addition, the lubricant oil of most gear drive all provides lubricated by the machine band oil pump in the gear-box lubricating component, this class formation often needs a pair of gear pair to guarantee the rated speed of lubricating pump, complex structure, and being subject to the gear-box input speed, the situation lower tooth roller box lubricants capacity bigger in the input speed amplitude of variation is difficult to be guaranteed.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, especially at the leakage of oil problem of working and bringing potential existence under the gear-box inclination operating mode, and provide a kind of simple in structure, and easy accessibility, easy to use, be used for the gear-box of underwater dredge pump reliably.
The purpose of this utility model is finished by following technical solution, it mainly is made up of left input block, right input block, output block, casing and pipeline component, about two input blocks by Bearing Installation on casing, the output gear of described output block is connected on the output shaft by curing, its integral body by Bearing Installation on casing, it is characterized in that described two input blocks and output block are arranged horizontally, and input end and output terminal lay respectively at a relative side of casing; The junction of described output block and casing is provided with a sealing configuration.
Described sealing configuration includes one by being bolted to the output sealing cover on the casing, is provided with three road outside framework oil seals between this output sealing cover and the output shaft, and is separated by two spacer rings between the described three road outside framework oil seals; Also have a lining of being made by high-abrasive material between outside framework oil seal and output shaft, this lining is enclosed on the output shaft by the transition connection, then has a block pressur plate to be connected by bolt on the output sealing cover in the outside of described outside framework oil seal.
For the gear-box lubrication problem, the utility model adopts electric-motor pump group in addition, so just can avoid the problem that can't guarantee at the bigger situation lower tooth roller box lubricants capacity of gear-box input speed amplitude of variation, can save a pair of gear pair simultaneously, simplified structure is saved cost.
The utlity model has simple in structure, easy accessibility, characteristics such as easy to use, reliable.
Description of drawings
Fig. 1 is a transmission principle schematic representation of the present utility model.
Fig. 2 is the structural representation of sealing mechanism described in the utility model.
Embodiment
Below the utility model is described in detail: shown in Figure 1, the utility model mainly is made up of left input block 1, right input block 1, output block 2, casing 3 and pipeline component, about two input blocks 1 by Bearing Installation on casing 3, the output gear of described output block 2 is connected on the output shaft by curing, its integral body by Bearing Installation on casing 3, described two input blocks 1 are arranged horizontally with output block 2, and input end and output terminal lay respectively at a relative side of casing 3; Described output block 2 is provided with a sealing configuration 4 with the junction of casing 3, with guarantee gear-box under inclination work operating mode output terminal to water with to the sealing effect of oil.
The sealing configuration 4 of described output terminal as shown in Figure 2, it is mainly by output sealing cover 5, by being bolted on the casing 3, the stuffing box packing and the O type circle of output terminal have been cancelled, change into and be provided with three road outside framework oil seals 7, separate by two spacer rings 11 between the three road outside framework oil seals 7, can open screw 8 so that add the gap of solid lubricant inside at output sealing cover 5 corresponding positions at spacer ring 11, thereby guarantee the lubricated of outside framework oil seal 7, the lining 8 that a high-abrasive material is then arranged between outside framework oil seal 7 and output shaft 10, the surface that lining 8 contacts with outside framework oil seal 7 is through hardening processing, can guarantee the hardness requirement on 7 pairs of engagement shaft surfaces of outside framework oil seal like this, greatly reduce cost with respect to 10 of the output shafts that directly harden, can prevent that output shaft 10 is worn simultaneously.Lining 8 on output shaft 10, by shaft block ring 9 to it carries out axially locating simultaneously by the transition connecting sleeve.Then have a block pressur plate 12 to be connected by bolt on the output sealing cover 5 in the outside of outside framework oil seal 7, retaining is avoided oarse-grained foreign material to enter inside and is caused outside framework oil seal 7 wearing and tearing in outside framework oil seal 7 outsides.The structure that the utility model adopts is more reliable than the conventional seals structure, simple and practical.
Gear-box described in the utility model, consider that main frame is input as motor, and the rotating speed of motor amplitude of variation is bigger, if adopt uni-drive gear box to carry the mode of machine band oil pump feed, the gear box lubricating oil amount can't remain on a stable scope, therefore the described gear-box of this patent takes to replace with the motor-drive pump group mode of machine band oil pump feed, guarantees the lubricants capacity of gear-box by the stable fuel feeding of electric-motor pump group, has guaranteed the stability of lubrication system when having simplified gear box structure.
