Abstract
The utility model relates to a speed reducer, particularly to a speed reducer special for a marine engine room crane system. The speed reducer is used for ships. The speed reducer comprises an elevating seat and a base. An elevating shaft sleeve extending upwards is plugged in the elevating seat. The elevating shaft sleeve sleeves a lead screw shaft. The base is arranged on the elevating shaft sleeve. The head part of the lead screw shaft extends into the base and is sleeved with a worm gear. A worm shaft is arranged in the base and engaged with the worm gear for transmission. An oil sealing layer is arranged between the lead screw shaft and the base. The speed reducer is compact in structure, improved in usage performance, and prolonged in service life; and the speed reducer has a relatively good anti-corrosion property.
Description
Technical field
The utility model is a kind of speed reducer, and particularly a kind of marine cabin driving system special reduction gear, for boats and ships.
Background technique
Speed reducer structure relative complex of the prior art, and easily produce high temperature in the process using, thereby affect the stability of transmission, speed reducer, to the requirement of temperature sensitivity very, in the time of low temperature, can cause using having some setbacks simultaneously, cannot keep transmitting accuracy, boats and ships are in the time of ocean operation simultaneously, and Environmental Conditions is more complicated, and relative adaptability is poor.
Chinese patent 200520116829.4, a kind of reduction gears mechanism is disclosed, comprise be provided with upper head plate, end plates and lower end sheet sleeve, input shaft, be provided with out the output shaft of shaftgear, it also comprises the train of reduction gears of a connection input shaft and output shaft, described train of reduction gears comprises the rotating shaft being located between upper head plate and lower end sheet, rotating shaft lower end is provided with and input shaft meshed gears one, and rotating shaft upper end is provided with and goes out shaftgear meshed gears two.This complex structure, and adaptability is poor, causes transmitting accuracy to decline, the stability that impact is used.
Model utility content
The utility model is mainly to solve the deficiencies in the prior art, compact structure, the marine cabin driving system special reduction gear of assurance deceleration function transmission effect.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of marine cabin driving system special reduction gear, comprise elevating bracket and support, in described elevating bracket, be plugged with upwardly extending lifting axle sleeve, in described lifting axle sleeve, be provided with screw axis, the top of described lifting axle sleeve is provided with support, and the head of described screw axis extends in support, the head cover of described screw axis has worm gear, in described support, be provided with worm shaft, the transmission that is meshed with worm gear of described worm shaft, is provided with oil sealing layer between described screw axis and support.
As preferably, between described screw axis and the bottom of support, between the upper end of screw axis and support, locate mutually by bearing respectively between the two ends of worm shaft and support, between the bearing on screw axis top and support, be provided with bearing cap, the right-hand member of worm shaft left end, worm shaft is respectively equipped with end cap, and described end cap and bearing connect.
As preferably, between described lifting axle sleeve and elevating bracket, locate mutually by fixed cover, described fixed cover and lifting axle sleeve fix by set screw, and described screw axis is located by screw rod bushing mutually with lifting axis inner room, and described screw rod bushing and screw axis fix by screw.
As preferably, the bottom of described support is attachment face, and the edge of described support is provided with clamping bolt.
This structural entity intensity is relatively high, and stability is high, and transmission performance is outstanding in use, brings good using effect.
Therefore, the marine cabin driving system special reduction gear that the utility model provides, compact structure, promotes usability, increases the service life, and has stronger corrosion resistance.
