Abstract

The utility model relates to a ring rolling machine which belongs to the technical field of machine working. The ring rolling machine is composed of a roller 1, an air cylinder 2, a transmission shaft 3, a motor 4, a main body 5 and a speed reducer 6, wherein the speed reducer 6 is composed of a large gear wheel 7, a bearing sleeve 8, an output shaft 9, a gear shaft 10 and a belt pulley 11, the motor 4 is driven by the gear shaft 10 through the belt pulley 11 and the gear shaft 10 drives the output shaft 9 which is supported by the bearing sleeve 8 through the large gear wheel 7 and makes the roller 1 act through the transmission shaft 3. The ring rolling machine has the advantages of wide working range, high working quality, energy saving, compact structure, high concentricity, low failure rate and high production rate and is mainly suitable for bearing processing enterprises.

Description

A kind of Ring Rolling Machine

Technical field

The utility model belongs to the Machining Technology field.

Background technology

First generation φ 250 Ring Rolling Machines of watt axle group development, by use for many years, many problems have been found, the decelerator part of this equipment particularly, employing be the 45W motor, come transferring power by the turbine bar, this kind of drive not only makes the oily temperature rise of decelerator too high, the turbine serious wear, and maintenance is complicated, has a strong impact on company cost and task.

Summary of the invention

The purpose of this utility model just provides that a kind of range of work is wide, crudy is high, energy-conservation, compact conformation, concentricity height, fault is few, productivity ratio is high Ring Rolling Machine.

Technical solution of the present utility model is, a kind of Ring Rolling Machine is made of roll milling wheel 1, cylinder 2, power transmission shaft 3, motor 4, fuselage 5 and decelerator 6, and decelerator 6 is made of gear wheel 7, bearing holder (housing, cover) 8, output shaft 9, gear shaft 10 and belt pulley 11; Motor 4 is by belt pulley 11 driven gear axles 10, and gear shaft 10 drives the output shaft 9 that is supported by bearing holder (housing, cover) 8 by gear wheel 7, makes roll milling wheel 1 action through power transmission shaft 3.

The modulus of gear wheel 7 is 8, the number of teeth is 59, and the modulus of gear shaft 10 is 8, the number of teeth is 15.

The beneficial effect that the utility model reached is, original decelerator part is transformed into present gear transmission mode by the turbine and worm kind of drive, improves Ring Rolling Machine service life more than 5 times; Work drive motor is reduced to 37KW by 45KW, has reduced power consumption; Simultaneously original working cylinder increases to 500mm by φ 450mm, and it is 8.8tf that spreading power is increased by original 7.2tf, has enlarged the range of work of forging, has improved the crudy of forging; The power transmission shaft size that extended in addition greatly facilitates changing of workman and lives through journey, has shortened and has changed live time.
