Novel special speed reducer for boring machine

Abstract

The invention provides a novel special speed reducer for a boring machine. The novel special speed reducer comprises a motor, a spindle, a bearing sleeve, first bearings and a shell, which are sleeved at the outside of the spindle from inside to outside, and a transmission mechanism arranged in the shell, wherein the bearing sleeve comprises a spindle sleeve and inner sleeves arranged on inner sides of both ends of the spindle sleeve, the first bearings are arranged on both ends of the outer side of the spindle sleeve, inner rings and outer rings of the first bearings are fixedly connected with the outer side of the spindle sleeve and the inner side of the shell respectively, the spindle sleeve is connected with the motor through the transmission mechanism, and the transmission mechanism comprises a fourth level transmission device, a third level transmission device, a second-level transmission device and a first-level transmission device, which are connected in sequence. The novel special speed reducer has the advantages that existing power source structure is replaced, so that the processing precision and the efficiency of the boring machine are improved, the power system is integrated, and the vibration of the spindle, the manpower consumption and the maintenance cost are reduced; the novel special speed reducer can be fixed to any position of the spindle by a torque arm board; a servo motor drives the spindle to rotate, so that the volume of the speed reducer is compact, energy is saved, the overload capacity is high, and the novel special speed reducer has the sense of science and technology.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a new type of reducer specially used for boring and arranging. Background technique [0002] The rudder shafting boring process equipment is mainly a precision special equipment for boring cylindrical or conical holes and end faces such as rudder stock, rudder pin hole, shaft tube hole, etc. Since shipyards currently use keyless connections and hydraulic expansion installation methods for the installation of rudders and propellers, the processing technology requirements for holes are very high. This not only requires the operating accuracy of the staff, but also the performance and machining accuracy of the boring row are also very important. During the machining of the boring row, the rotating power of the boring row spindle is transmitted by the reducer.

Problems solved by technology

[0003] Currently, if image 3 It is a structural schematic diagram of an existing power transmission form in which the reducer drives the main shaft to rotate. It can be seen that the power transmission form of the sprocket driving the main shaft is divided into several components, which causes inconvenience to the installation, and this chain The form of wheel transmission power is easy to bring the vibration to the main shaft of the boring bar; Figure 4 It is a structural schematic diagram of another existing power transmission form in which the reducer drives the main shaft to rotate. It can be seen that this worm gear transmission mode has disadvantages such as low mechanical efficiency, difficult processing of the worm gear, and easy wear of the worm gear.
