Description
Technical field
The pendulum that the utility model relates on the sheet billet continuous casting and rolling production line is cut equipment, refers to that particularly a kind of pendulum with good cooling and lubricating performance cuts speed reducer.
Background technique
Sheet billet continuous casting and rolling production line (be called for short CSP production line) is the novel production line of German western mark company development and Design, and it is the key equipment on the CSP production line that pendulum is cut equipment, and it is used to shear base head, base tail, and strand is cut into finished product rolls up desired length.When stove and milling train when accidents happened, it is cut into broken section with the strand that is cast out.So it is very crucial pendulum to be cut the operation maintenance of equipment, and the emphasis that pendulum is cut equipment if speed reducer goes wrong, then is the substantial equipment accident at its speed reducer, can not recover in the short time, whole C SP production line will stop production.Therefore, it is particularly important to guarantee that pendulum is cut normal operation and working life of speed reducer, and high speed shaft bearing lubricated and that the cooling pendulum is cut in the speed reducer is to guarantee to put to cut the main path that speed reducer normally moves and increases the service life.
At present, western mark company cuts speed reducer for pendulum and has designed a Lubricating-oil Station separately, specially pendulum is cut speed reducer equipment and is lubricated and cools off.But the Bearing Installation place of cutting the speed reducer high speed shaft at pendulum only offers an oil inlet passage; Get into speed reducer inside from the cutting oil of oil-feed house steward output through this oil inlet passage; Bearing and high speed shaft are cooled off and lubricate, flow to the deceleration box bottom next time in action of gravity then, and flow back into fuel tank through the main return tube of deceleration box bottom; Cutting oil in the fuel tank is sucked up to the oil-feed house steward again, so circulation.Practice shows; Owing to have only a circulation loop, not enough to the lubricated cooling effect of bearing and high speed shaft, the rotating speed of high speed shaft long-time running is high; Heating value is big; Bearing temperature is in 65～70 ℃ hot environment for a long time, not only causes speed reducer fault and the working life of having reduced bearing easily.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of pendulum with good cooling and lubricating performance to cut speed reducer; It is not only simple in structure, easy to maintenance; And can make high speed shaft and bearing in the casing obtain abundant cooling and lubricating, and reduce running temperature, increase the service life.
For realizing above-mentioned purpose; The utility model designs the pendulum with good cooling and lubricating performance and cuts speed reducer; Comprise the casing that combines by upper box lid and following case lid, be used to install high speed shaft, second, the 3rd and the 4th; The Bearing Installation place that said nowel covers corresponding to high speed shaft offers first oil inlet passage that links to each other with the oil-feed house steward; The said return opening place, bottom of case lid down is provided with the main return tube that links to each other with fuel tank, and the Bearing Installation place corresponding to high speed shaft on the said upper box lid offers second oil inlet passage, and said second oil inlet passage links to each other with the oil-feed house steward through the oil-feed arm.
Further, said oil-feed arm is provided with oil level indicator, switch valve and pressure gauge, is used to monitor the working condition of cutting oil.
Further; The bearing (ball) cover bottom of said high speed shaft also offers drainback passage, and said drainback passage links to each other with main return tube through oil returning branch pipe, so that make the cutting oil that increases at high speed shaft bearing place can in time flow back to fuel tank; Unlikely overflowing saved grease.
The advantage of the utility model is: utilize existing pendulum to cut the structure space of speed reducer self; Bearing lubrication circuit to high speed shaft in the speed reducer is transformed; Offer drainback passage at upper box lid corresponding to the bearing (ball) cover bottom that the Bearing Installation place of high speed shaft offers second oil inlet passage and high speed shaft respectively; Make the high speed shaft run up obtain abundant cooling and lubricating, the lubricant oil that increases simultaneously again can be in time through flowing back to fuel tank, thereby can effectively reduce the parts running temperature; Prolong parts working life, avoid the substantial equipment accident to take place.In addition, its transformation is simple and convenient, invests cheaply, and effect is obvious.
Description of drawings
Fig. 1 cuts the structural representation of speed reducer for a kind of pendulum with good cooling and lubricating performance.
Fig. 2 is the A-A sectional structure schematic representation among Fig. 1.
Among the figure: 1, the second 2, the three 3, the four 4 of high speed shafts, upper box lid 4, following case lid 6; First oil inlet passage 7, return opening 8, main return tube 9, the second oil inlet passages 10, bearing (ball) cover 11, oil-feed arm 12; Oil level indicator 13, switch valve 14, pressure gauge 15, drainback passage 16, oil returning branch pipe 17.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The pendulum that has good cooling and lubricating performance shown in the figure is cut speed reducer; Comprise 6 that combine by upper box lid 5 and following case lid, be used to install high speed shaft 1, second 2, the 3rd 3 and the 4th 4 casing; Bearing Installation place corresponding to high speed shaft 1 on the following case lid 6 offers first oil inlet passage 7 that links to each other with oil-feed house steward (not shown), and bottom return opening 8 places of following case lid 6 are provided with the main return tube 9 that links to each other with fuel tank.Internal structure according to upper box lid 5; Bearing Installation position corresponding to high speed shaft 1 on upper box lid 5 is vertically bored a hole from the bottom up; Again along continuous straight runs on upper box lid 5 from outside in to boring a hole, with vertical hole cross-coincidence, thereby be processed into second oil inlet passage 10.Connect an oil-feed arm 12 from main oil inlet pipe nearby and link to each other with second oil inlet passage 10, cutting oil just can carry out cooling and lubricating to high speed shaft 1 through 10 inputs of second oil inlet passage.Oil level indicator 13, switch valve 14 and pressure gauge 15 also are installed on oil-feed arm 12, are used for the monitoring bearing lubrication circumstances.A drainback passage 16 is offered in bearing (ball) cover 11 bottoms at high speed shaft 1, makes it pass through oil returning branch pipe 17 and links to each other with main return tube 9, makes the cutting oil of increase in time get back to fuel tank, saves grease.
