Abstract

The utility model discloses a thick well rolling mill speed reducer connecting device of high-speed wire rod mainly includes sphere external tooth, case end ring gear, components of a whole that can function independently speed reducer tooth cover, and case end ring gear passes through terminal surface tooth, bolt handle and is connected with components of a whole that can function independently speed reducer tooth cover. The utility model has the advantages that split type design of components of a whole that can function independently speed reducer tooth cover and case end ring gear can the significantly reduced because inside and outside tooth wearing and tearing change the time and the cost of spare part again between case end ring gear and the sphere external tooth, improves production efficiency.

Description

Speed reducer connecting device of high-speed wire rod rough and medium rolling mill
Technical Field
The utility model relates to a drive machine field, concretely relates to speed reducer connecting device among thick well rolling mill transmission system of high-speed wire rod.
Background
As shown in fig. 1, in the existing high-speed wire rough intermediate rolling mill transmission system, the speed reducer gear sleeve is generally of an integral structure, the internal teeth and the spherical external teeth on the speed reducer gear sleeve realize power transmission through gear engagement, spare parts need to be replaced again due to frequent and serious abrasion of the internal and external teeth, the speed reducer gear sleeve and the speed reducer and the spline shaft hole connected with the speed reducer gear sleeve need to be disassembled at the moment, and particularly, in the high-speed wire rough intermediate rolling mill transmission system which is vertically installed, the speed reducer needs to be lifted out together to be replaced, time and labor are wasted, and the production efficiency is affected.
Disclosure of Invention
An object of the utility model is to avoid prior art's weak point, provide a rolling mill speed reducer connecting device in high-speed wire rod is thick, make adapting unit maintenance and change in the rolling mill transmission system in the high-speed wire rod convenient more, swift.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a thick well rolling mill speed reducer connecting device of high-speed wire rod, mainly includes sphere external tooth (1), case end ring gear (6), components of a whole that can function independently speed reducer tooth cover (5), and transmission is realized through gear engagement (3) in sphere external tooth (1) and case end ring gear (6), and its characterized in that case end ring gear (6) pass through terminal surface tooth, bolt handle and be connected with components of a whole that can function independently speed reducer tooth cover (5).
Optionally, the box end gear ring (6) is connected with the split speed reducer gear sleeve (5) through end face teeth and pins so as to realize quick assembly and disassembly.
Preferably, a sealing ring (7) structure is arranged to realize sealing of a gear meshing (3) part between the spherical external teeth (1) and the box end gear ring (6), so that the gear pair is lubricated and lubricating oil leakage is avoided.
Preferably, the spherical external teeth (1) and the box end gear ring (6) are made of steel materials, so that the service life of the gear is prolonged.
The utility model has the advantages that: the speed reducer connecting device in the high-speed wire rod rough and medium rolling mill transmission system can greatly reduce the time and cost for replacing spare parts between the box end gear ring and the spherical external teeth due to the abrasion of the internal and external teeth through the split design of the speed reducer gear sleeve, and improve the production efficiency; compare whole type structure simultaneously, need not change the whole speed reducer tooth cover of taking the internal tooth, only need change case end ring gear, and the forging blank utilization ratio of case end ring gear is high, and the material is few, can practice thrift manufacturing cost greatly.

Detailed Description
Embodiments of the present invention will be further described with reference to the accompanying drawings, and fig. 2 is a schematic diagram illustrating the operation of an apparatus according to an embodiment of the present invention. It should be understood that fig. 2 of the present disclosure highlights the components of an apparatus according to an embodiment of the present invention, that is, fig. 2 is not intended to illustrate each individual component in an apparatus of the present invention.
The first embodiment is as follows: as shown in fig. 2, the speed reducer connecting device of the high-speed wire rough and medium rolling mill mainly comprises spherical external teeth 1, a box end gear ring 6 and a split speed reducer gear sleeve 5, wherein the spherical external teeth 1 and the box end gear ring 6 are in transmission through gear meshing 3, and the speed reducer connecting device is characterized in that the box end gear ring 6 and the split speed reducer gear sleeve 5 are connected through end face teeth, and are formed by a bolt handle. The speed reducer in the transmission system is respectively transmitted to a box end gear ring 6 through a connecting shaft, a speed reducer 4 and a split speed reducer gear sleeve 5, and the spherical external teeth 1 are driven to rotate through gear meshing 3. When the spherical external teeth 1 and the box end gear ring 6 need to be replaced due to abrasion, the spherical external teeth 1 and the box end gear ring 6 can be directly disassembled, the split speed reducer gear sleeve 5 does not need to be disassembled, the disassembly and assembly work is greatly simplified, and the replacement and maintenance time is saved.
Example two: on the basis of the first embodiment, the bolt between the box end gear ring 6 and the split speed reducer gear sleeve 5 is replaced by pin connection, so that the quick assembly and disassembly are realized.
Example three: on the basis of the first embodiment or the second embodiment, the sealing ring 7 is arranged to realize the sealing of the gear meshing part 3 between the spherical external teeth 1 and the box end gear ring 6, so that the gear pair is lubricated and the lubricating oil is prevented from leaking.
Example four: on the basis of the first embodiment or the second embodiment, the spherical external teeth 1 and the box end gear ring 6 are made of steel materials, so that the service life of the gear is prolonged.
The foregoing description is intended to illustrate and not limit the invention, and those skilled in the art will appreciate that variations, modifications and equivalents may be made in the above disclosure without departing from the spirit and scope of the invention as defined in the appended claims.
