Description
Technical field
The present invention relates to a kind of turning gear, particularly a kind of turning gear that is used for crawler crane.
Background technology
At present, the employed pivoting support of crawler crane mainly contains three kinds more than 1000 tonnes, a kind of is three row's roller pivoting supports, transmit the vertical load and the tilting moment of turntable by three row's rollers, but the transportation width of this pivoting support has surpassed 3500mm, belong to tertiary highway transportations width limitations, so crawler crane need pay the cost of transportation of more highways and gap bridge when transition, cause the use cost height; Another kind of pivoting support adopts solid heavy caliber round steel to locate as horizontal direction, area of contact adopts the lubricating oil friction, lubrication up and down, but this pivoting support can only transmit vertical load, can not transmit tilting moment, therefore the pivoting support of this mode only is useful on the crawler crane that has only the super-starting balance weight dolly, and bigger for the unbalance loading influence that plays heavy lift, individual transportation weight is bigger, and use is restricted; The third is the pivoting support combination of more large-tonnage use, the center adopts 3500mm to transmit tilting moment with interior pivoting support, increase the revolution driving trolley in the pivoting support outer rim and transmit vertical load, this pivoting support unitized construction is stressed better, but it is very inconvenient to split transportation, cost is higher, so this kind pivoting support is applicable to the crawler crane more than 3000 tonnes.
Summary of the invention
The purpose of this invention is to provide a kind of integral structure simple, bear vertical load and the tilting moment ability is strong, easy disassembly, rotary supporting device that cost is low, to satisfy 1000 tons of revolution requirements, overcome the deficiencies in the prior art to 3000 tons of crawler cranes.
The turning gear that is used for crawler crane of the present invention, comprise gear ring 1, it is characterized in that: on the circumference of gear ring 1, be provided with ring recess 9, last circle 5 places in the ring recess 9, between the bottom surface of the bottom surface of last circle 5 and ring recess 9, be arranged with at least two and enclose resistance to compression rolling bodys 3, be provided with cage ring 2 between the outer ring resistance to compression rolling body that inner ring resistance to compression rolling body is adjacent, seal 6 outside the notch outside that is positioned at ring recess 9 at the excircle place of gear ring 1 is provided with, be provided with outer ring antidumping rolling body 8 between seal outside 6 and the last circle 5, between last circle 5 and inboard, ring recess 9 outside suitable for reading, be provided with outer ring radial rolling body 4.
The turning gear that is used for crawler crane of the present invention, the notch inboard that the inner periphery place of wherein said gear ring 1 is positioned at ring recess 9 is provided with seal 7, interior seal 7 and on circle be provided with inner ring antidumping rolling body 11 between 5, between last circle 5 and ring recess 9 inner edge suitable for reading inboards, be provided with inner ring radial rolling body 12.
The turning gear that is used for crawler crane of the present invention, wherein said cage ring 2 is provided with boss, and the groove 10 on this boss and last circle 5 bottom surfaces matches.
The turning gear that is used for crawler crane of the present invention compared with prior art has that integral structure is simple, low cost of manufacture, use cost are low, easy to use, easy disassembling, bear vertical load and the strong advantage of tilting moment ability.
