Abstract
The invention discloses a transmission force intermediate temperature control device inside a rotary cement kiln. The transmission force intermediate temperature control device comprises a centering rod, a pushing rod, protective covers and a piston rod connector. The end opening, provided with a compression spring, of the centering rod is movably connected with an elastic collar. Four bearings are symmetrically arranged at the two ends of a thrust bearing. The pushing rod wraps a system composed of the centering rod and the thrust bearing. Two bearing sleeves are arranged in the positions where the bearings are connected with the pushing rod. The end, close to the thrust bearing, of the pushing rod is connected with a belleville spring. The two protective covers are arranged at the top, corresponding to the two ends of the thrust bearing, of the pushing rod. The elastic collar is movably connected with the thrust bearing. A temperature controller is arranged in the elastic collar. The structure is simple, and the thrust bearing of an ach structure is adopted, so that the stress intensity of the bearings is increased. The temperature controller controls the movement of the elastic collar, the condition that the centering rod is blocked in an inner hole of the pushing rod due to high-temperature expansion is avoided, and unnecessary loss produced in production of the rotary cement kiln is reduced.
Description
Technical field
The present invention relates to a kind of middle attemperating unit of power transmission of cement rotary kiln inside.
Background technology
Rotary kiln, as the nucleus equipment of cement production enterprise, under the prerequisite of normal operation not interrupting kiln, the various detections of rotary kiln are all being developed to mobilism, the tugboat axle during but the direct ejection of hydraulic cylinder piston rod can not be used to rotate, therefore just there is the power transmission middle device of novel rotary kiln inside, in the middle device design process of rotary kiln novel mechanical structures, when axial force measuring device uses, the motive force of hydraulic cylinder will be applied to one end of tugboat axle, to balance the axial force suffered by tugboat, make it the state reaching stress balance, if the motive force of hydraulic cylinder can not act on the axis of tugboat axle, so tugboat axle moment can be given while giving tugboat axle applied thrust, the accuracy of measurement result is so not only made to reduce, also may be destroyed supporting construction when thrust is larger, so the effect of power transmission middle device is exactly guide penetrator ram, the thrust of hydraulic cylinder is applied to drags in axle stub, but the thrust bearing in traditional power transmission middle device generally adopts rectangular configuration, low by force intensity, and centering rod is generally all made up of aluminum metal, the degree of usual metal temperature influence is larger, and due to long work, temperature in equipment is more and more higher, especially bearing temperature, if things go on like this device damage can be caused, more exchange device is frequent, increase production cost, even if leave gap between centering rod and penetrator ram, also can Yin Wendu too high and occur stuck phenomenon, thus the unnecessary loss in causing rotary kiln to produce, can not meet the industrial demand of modernization.
Summary of the invention
The object of this invention is to provide the middle attemperating unit of power transmission of the cement rotary kiln inside that a kind of efficiency is high, the life-span is long.
The technical solution adopted in the present invention is:
A kind of power transmission middle device of cement rotary kiln inside, comprise centering rod, penetrator ram, protective cover and piston rod connector, described centering rod one end and middle part are provided with Compress Spring, the port activity that described centering rod is provided with Compress Spring connects circlip, described circlip connects thrust bearing, described thrust bearing two ends are arranged with 4 bearings, described penetrator ram wraps the system of centering rod and thrust bearing composition, described bearing and penetrator ram junction arrange two bearing holder (housing, cover)s, described penetrator ram connects butterfly spring near thrust bearing one end, penetrator ram top corresponding to described thrust bearing two ends is provided with two protective covers, described two protective cover one end are fixed with bolt respectively, described circlip is flexibly connected with thrust bearing, temperature controller is provided with in described circlip.
Described centering rod is hollow wood construction.
Described thrust bearing is domes.
The invention has the beneficial effects as follows: structure is simple, adopt the thrust bearing of domes, what increase bearing is subject to force intensity, hollow wood construction quality is light, and it is not obvious by variations in temperature, temperature controller controls the movement of circlip simultaneously, avoids the situation because high-temperature expansion causes centering rod to be stuck in penetrator ram endoporus, decreases the unnecessary loss in rotary kiln production.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, centering rod, 2, penetrator ram, 3, Compress Spring, 4, protective cover, 5, circlip, 6, thrust bearing, 7, bearing holder (housing, cover), 8, butterfly spring, 9, bolt, 10, piston rod connector, 11, bearing, 12, temperature controller.
Detailed description of the invention
The power transmission middle device of a kind of cement rotary kiln inside as shown in Figure 1, comprise centering 1 bar, penetrator ram 2, protective cover 4 and piston rod connector 10, centering rod 1 one end and middle part are provided with Compress Spring 3, the port activity that centering rod 1 is provided with Compress Spring 3 connects circlip 5, circlip 5 connects thrust bearing 6, thrust bearing 6 two ends are arranged with 4 bearings 11, penetrator ram 2 wraps the system of centering rod 1 and thrust bearing 6 composition, bearing 11 and penetrator ram 2 junction arrange two bearing holder (housing, cover)s 7, penetrator ram 2 connects butterfly spring 8 near thrust bearing 6 one end, penetrator ram 2 top corresponding to thrust bearing 6 two ends is provided with two protective covers 4, two protective cover 4 one end are fixed with bolt 9 respectively, circlip 5 is flexibly connected with thrust bearing 6, temperature controller 12 is provided with in circlip 5, control the movement of circlip 5, once temperature is too high, circlip 5 and thrust bearing 6 will disconnect, avoid the situation because high-temperature expansion causes centering rod 1 to be stuck in penetrator ram 2 endoporus, decrease the unnecessary loss in rotary kiln production, centering rod 1 is hollow wood construction, quality is light, and it is not obvious by variations in temperature, efficiently reduce the quality of whole device, thrust bearing 6 is domes. what increase thrust bearing 6 is subject to force intensity, add the service life of equipment.
