Abstract
The utility model relates to speed reducer categories, in particular to a vertical type cycloidal pin gear speed reducer capable of resisting high temperature and heavy load working conditions. The heavy load high temperature resistance vertical type cycloidal pin gear speed reducer comprises a speed reducer body. The speed reducer body is provided with a rack, a lengthened output shaft and a seal device, and is further provided with a rack base. The rack is connected on the rack base. A copper bush is arranged on the outer circumference of the lengthened output shaft. A bearing base is arranged outside the copper bush. The seal device is located between the lengthened output shaft and the bearing base. The seal device is tightly compressed in the bearing base by a pressing cover through bolts. According to the heavy load high temperature resistance vertical type cycloidal pin gear speed reducer, rack support points are additionally arranged on the lengthened output shaft, and therefore the speed reducer body is enabled to be capable of bearing big radial force. A mechanism of the rack is made of special materials, and therefore the speed reducer body is enabled to be capable of bearing working conditions with high temperature and high humidity. Asbestos packing is adopted for sealing a structure of the rack, and better seal effect is achieved. The copper bush is served as a positioning bearing. The copper bush has a better performance of resisting high temperature under the condition that speed of the output shaft of the speed reducer is not high.
Description
Technical field
The utility model relates to the speed reducer class, especially a kind of vertical cycloid pinwheel reduction gear that can bear under high temperature, the heavily loaded working condition.
Background technique
The characteristics such as cycloidal planetary gear speed reducer is simple in structure with it, maintenance is convenient are widely used in the industries such as chemical industry, food and medicine.But because a lot of work under bad environment needs cycloidal planetary gear speed reducer can bear the working condition of high temperature, heavy duty.This moment, the common cycloid pin gear speed reducer was owing to the reasons such as structural limitations can't be applicable to the abominable working environment of this kind.
What the cycloidal planetary gear speed reducer output shaft adopted is double-cantilever structure, so after output shaft bore larger radial load, the output shaft length of shaft can not be oversize, otherwise the situation such as off-axis occurs easily.Simultaneously because operating ambient temperature is high, and moisture is large, so the necessary high temperature resistant humidity of speed reducer output terminal; Since the frame mechanism supports speed reducer output shaft bear outside large radial force, and need to bear the environment of hot and humid degree, so common sealing bearing can't be applicable to the strong point as frame mechanism.
The model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of vertical cycloid pinwheel reduction gear that can bear the working environment of high-temperature and high humility.
The technological scheme that its technical problem that solves the utility model adopts is: the high temperature resistant vertical cycloid pinwheel reduction gear of a kind of heavy duty, comprise the speed reducer body, described speed reducer body has output shaft and the seal arrangement of frame, lengthening, described speed reducer body also has support, described frame is connected on the support, the excircle of the output shaft of described lengthening is provided with copper sheathing, copper sheathing is provided with bearing support outward, described seal arrangement is between the output shaft that lengthens and bearing support, and described seal arrangement is pressed in the bearing support by bolt by gland.
Described seal arrangement is asbestos packing, and asbestos packing is owing to its oil suction and can store oily characteristic, has the effect of heat-resisting humidity as sealing.
The material of described frame is the magnesium iron material, and impact resistance strengthens.
Described bearing support adopts the heat-resistance stainless steel material.
The material of described copper sheathing is aluminum bronze, wear resistance heat resistance and damp proof anti-enhancing.
The beneficial effects of the utility model are: the utility model lengthens output shaft increases the frame support point simultaneously, so that the speed reducer body can bear large radial force, frame mechanism adopts special substance, so that the speed reducer body can bear the working environment of high-temperature and high humility; Rack construction adopts asbestos packing to do sealing, reaches better sealing effect; Copper sheathing is made positioning bearing, and in the not high situation of speed reducer output shaft rotating speed, the Wear-resistant, high-temperature resistant resistance to moisture of copper sheathing is better.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. speed reducer body, 2. frame, the output shaft that 3. lengthens, 4. seal arrangement, 5. support, 6. copper sheathing, 7. bearing support, 8. gland.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Heavily loaded high temperature resistant vertical cycloid pinwheel reduction gear as shown in Figure 1, comprise speed reducer body 1, output shaft 3 and seal arrangement 4 that speed reducer body 1 has frame 2, lengthens, speed reducer body 1 also has support 5, frame 2 is connected on the support 5, and the excircle of the output shaft 3 of lengthening is provided with copper sheathing 6, the copper sheathing 6 outer bearing supports 7 that are provided with, seal arrangement 4 is between the output shaft 3 that lengthens and bearing support 7, and seal arrangement 4 is pressed in the bearing support 7 by bolt by gland 8.
Lengthen the output shaft of speed reducer body 1, support by the output shaft increase of 7 pairs of speed reducer bodies 1 of bearing support of design on the frame 2, so that outside large radial force acts on the strong point on the frame 2, and do not affect speed reducer body 1 internal work load.Simultaneously because oil sealing belongs to quality of rubber materials, so aging easily in hot and humid degree environment, and frame 2 structures that increase partly separate the bearing end on the output shaft 3 that lengthens and the oil sealing of speed reducer body 1, avoid the high temperature moisture directly to contact the oil sealing of speed reducer body 1, guaranteed sealing reliability and the working life of speed reducer body 1.
Since frame 2 mechanism supports the output shaft 3 that lengthens of speed reducer body 1 bear outside large radial force, and need to bear the environment of hot and humid degree.So common sealing bearing can't be applicable to the strong point as frame 2 mechanisms, in the not high situation of speed reducer output shaft rotating speed, adopt copper sheathing 6 to replace common sealing bearing.
In frame 2 mechanisms, adopt asbestos packing as seal arrangement 4 behind support copper sheathing 2 bearings, asbestos packing is owing to its oil suction and can store oily characteristic, has the effect of heat-resisting humidity as sealing.Tighten up simultaneously the asbestos packing of compressing bearing support 7 interior installations by bolt with gland 8, make asbestos packing attached tightly between the output shaft 3 of bearing support 7 and lengthening, reach better sealing effect, after the in use for some time asbestos packing wearing and tearing, regulate the long term seal that gland 8 can guarantee asbestos packing simultaneously.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
