Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, and particularly to a lubricating device for the gears of a calender cooling drum. Background Art

[0002] As is well known, a calender is a key core equipment of a tire enterprise, with high production speed, large cord fabric tension, and high requirements for the quality of semi-finished products, thus having very high requirements for the stable operation of the equipment. The function of the calender cooling drum is to cool the rubber components, and at the same time provide calendering tension and production speed. The stable operation of this part is crucial for the entire calender.

[0003] Lubrication is the best way to maintain the transmission parts of the equipment. The traditional lubrication method for the gears of the calender cooling drum is manual lubrication. Limited by the fact that the gear transmission device is a closed space and can only be manually inspected and refueled when the machine is stopped, it affects the production efficiency of the equipment. At the same time, due to the uncontrollability of humans, it is impossible to refuel at fixed times and in fixed quantities. Moreover, the lubricating oil applied manually is easily extruded and dropped in large amounts when the gears mesh, which cannot guarantee long-term lubrication and causes a large amount of waste and environmental pollution. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a lubricating device for the gears of a calender cooling drum, which solves the common problem of manually adding lubricating oil to the calender cooling drum and ensures the lubrication effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a lubricating device for the gears of a calender cooling drum, which is provided with a reducer and a power system. The reducer and the power system are connected to the driving gear through a reducer transmission shaft. The driving gear meshes with the upper driven gear and the lower driven gear. The upper driven gear is connected to the cooling drum power shaft disc through a tensioning sleeve. The cooling drum power shaft disc and the cooling drum are fixed by bolts. The feature is that a lubricating oil pipe is arranged on one side of the upper driven gear. The outlet pipe orifice of the lubricating oil pipe is located above the side of the upper driven gear. The other end of the lubricating oil pipe is communicated with an oil storage tank. A spring-type pulsator is installed on the oil storage tank. An electromagnetic pneumatic reversing valve is connected to the pulsator. The air source is connected to the electromagnetic pneumatic reversing valve. The control system controls the valve closing of the electromagnetic pneumatic reversing valve.

[0006] The beneficial effect of the utility model is that an automatic refueling method with controllable cycle and controllable lubricating oil quantity is realized through the oil storage tank, the electromagnetic pneumatic reversing valve, the control system, and the lubricating oil pipe, which ensures the lubrication effect, reduces environmental pollution, reduces the labor intensity of maintenance personnel, reduces the equipment failure rate, ensures the stable operation of the equipment, and meets the production requirements.

[0010] In the figure, the utility model is provided with a reducer and a power system 1. The reducer and the power system 1 are connected to the driving gear 3 through the reducer transmission shaft 2. The driving gear 3 meshes with the upper driven gear 4 and the lower driven gear 5. The upper driven gear 4 is connected to the cooling drum power shaft disc 7 through the tensioning sleeve 6. The cooling drum power shaft disc 7 and the cooling drum 8 are fixed by bolts. The lower driven gear 5 is connected to another cooling drum power shaft disc through another tensioning sleeve. The cooling drum power shaft disc and another cooling drum are fixed by bolts. One side of the upper driven gear 4 is provided with a lubricating oil pipe 14. The outlet pipe orifice of the lubricating oil pipe 14 is located above the upper driven gear 4. The other end of the lubricating oil pipe 14 is communicated with the oil storage tank 12. A spring-type pulse generator 11 is installed on the oil storage tank 12. The electro-magnetic pneumatic reversing valve 9 is connected to the pulse generator 11. The air source 10 is connected to the electro-magnetic pneumatic reversing valve 9. The control system 15 controls the opening and closing of the valve of the electro-magnetic pneumatic reversing valve 9. A gland and a handle 13 are installed on the oil storage tank 12.

[0011] The speed reducer and power system 1 of the present utility model drives the rotation of the driving gear 3 through the speed reducer transmission shaft 2. The driving gear 3 drives the rotation of the upper driven gear 4 and the lower driven gear 5 by meshing with them. The upper driven gear 4 drives the rotation of the cooling drum power shaft disc 7 through the expansion sleeve 6, thereby driving the rotation of the cooling drum 8 to realize the normal operation of the entire transmission device. At the same time, the present utility model is provided with an oil storage device 12. Open the gland and handle 13, and add lubricating oil with a moderate viscosity to the oil storage device 12 in advance. A pulsator 11 is installed at the bottom of the oil storage device 12, and the pulsator 11 has a stroke adjustment function to meet the adjustment requirements of different oil output amounts for each pulse. The inlet of the electromagnetic pneumatic directional control valve 9 is connected to the output end of the air source 10, and the outlet of the electromagnetic pneumatic directional control valve 9 is connected to the input end of the pulsator 11. The control system 15 sends a signal to the electromagnetic pneumatic directional control valve 9, and compressed air enters the pulsator 11 to compress the spring to suck oil from the oil storage device 12. When the spring returns, the lubricating oil is added to the upper driven gear 4 through the lubricating oil pipe 14. The lubricating oil is brought to the driving gear 3 through adhesion on the upper driven gear 4 for meshing lubrication. The driving gear 3 then brings the lubricating oil into the lower driven gear 5 for meshing lubrication. By setting the refueling cycle and the refueling time each time in the control system 15, the system regularly sends a signal to the electromagnetic pneumatic directional control valve 9, thereby realizing the automatic timing and quantitative lubrication of the entire gear pair.
