Abstract

The utility model relates to a gap eliminating device of a crane rotation gear. The gap eliminating device of the crane rotation gear comprises a hydraulic drive part and a rotation gear outer gear which is installed on the hydraulic drive part, a servo motor is fixedly installed on one side, opposite to the hydraulic drive part, of the outer gear, and an output shaft of the servo motor is connected with the outer gear through flat keys. According to the set rotation torque of the servo motor, the servo motor is enabled to rotate with a hydraulic motor in an identical direction first, when the rotation reaches the set rotation torque, the servo motor stops moving, then the hydraulic motor drives a reducer to move, thus rotation impact is effectively eliminated, and noise of gear engagement is reduced. The gap eliminating device of the crane rotation gear has the advantages of being energy-saving, compact in structure, convenient to repair and the like.

Description

A kind of crane rotation gear is eliminated inter space device
Technical field
The utility model relates to a kind of crane rotation gear and eliminates inter space device, belongs to crane gear technical field peculiar to vessel.
Background technique
Present deck of ship crane rotation gear carries out preload power to output gear mechanically and eliminates tooth to the gap of tooth by motor driving, complex structure, and Installation and Debugging time length, inconvenient maintenance often have influence on the normal use of swiveling gear.
The model utility content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of crane rotation gear to eliminate inter space device, eliminates the gear transmission gap by the motor-driven gear gear ring.
The technological scheme that the utility model solves above technical problem is: provide a kind of crane rotation gear to eliminate inter space device, comprise the swiveling gear external gear on hydraulic driving part and the described hydraulic driving part of installation, relatively be installed with actuating motor with described hydraulic driving part one side on described external gear, described actuating motor output shaft adopts flat key to be connected with described external gear.
The technological scheme that the utility model further limits is: aforesaid crane rotation gear is eliminated inter space device, described hydraulic driving part comprises oil hydraulic motor, brake assembly and rotary reducer, described rotary reducer output shaft is connected with described external gear, described brake assembly is installed on the described oil hydraulic motor, and by the described rotary reducer of described fluid motor-driven.
Further, aforesaid crane rotation gear is eliminated inter space device, and described actuating motor and described rotary reducer are in same axis and are installed in respectively described external gear both sides.
The beneficial effects of the utility model are: the rotary torque that the utility model sets according to actuating motor, first actuating motor and oil hydraulic motor are turned round in the same way, when revolution reaches this moment of torsion, the actuating motor stop motion, then oil hydraulic motor drives the speed reducer motion, can effectively eliminate like this revolution and impact, reduce gear tooth noise, that this gear clearance elimination device has is energy-conservation, compact structure, the advantage such as easy to maintenance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment 1
The utility model provides a kind of crane rotation gear to eliminate inter space device, as shown in Figure 1, comprise the swiveling gear external gear 4 on hydraulic driving part and the installation hydraulic driving part, on external gear 4 relatively and hydraulic driving part one side be installed with actuating motor 7, actuating motor 7 is in same axis with rotary reducer and is installed in respectively the external gear both sides, the actuating motor output shaft adopts flat key 6 to be connected with external gear, the hydraulic driving part of the present embodiment comprises oil hydraulic motor 1, brake assembly 2 and rotary reducer 3, rotary reducer 3 output shafts are connected with external gear 4, brake assembly 2 is installed on the oil hydraulic motor 1, and by the fluid motor-driven rotary reducer.
In the present embodiment, actuating motor 7 being set rotation torque first is 10N.m, when loop wheel machine need to turn round left, allow actuating motor 7 to anticlockwise, when reaching the 10N.m of setting, the actuating motor stop motion drives rotary reducer 3 by hydraulic actuating fluid pressure motor 1 again and turns left, and realizes the rotation motion of loop wheel machine; When loop wheel machine need to be to right-hand rotation, allow actuating motor 7 to right rotation, when reaching the 10N.m of setting, the actuating motor stop motion drives rotary reducer 3 by hydraulic actuating fluid pressure motor 1 again and turns right, and realizes the rotation motion to the right of loop wheel machine.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
