Description
Technical field
The utility model relates to the speed reducer class, especially a kind of compact structure, the uniform horizontal cycloidal planetary gear speed reducer of heat radiation.
Background technique
What horizontal cycloidal planetary gear speed reducer adopted is cycloidal pin teeth engagement, planetary transmission principle, little with its volume, speed ratio is large, bearing capacity is strong, simple in structure and safeguard that the advantage such as convenient is widely used in the industries such as lifting, conveying, metallurgy, mine, building, weaving, as driving or speed reducer.
The key of horizontal cycloidal planetary gear speed reducer high-speed drive part mainly is at center pivoted arm place, setting-up eccentricity bearing on the pivoted arm of center.The center pivoted arm adds that the speed reducer internal structure is compact owing to be in the cycloidal planetary gear speed reducer core, causes easily heat radiation not smooth, and capacity eccentric bearing easily generates heat and premature failure.So to be floating structure proposed requirements at the higher level to material and the precision of speed reducer inner components and because main driving component cycloid wheel adopts in the cycloidal planetary gear speed reducer, otherwise cycloidal planetary gear speed reducer produces vibrations greatly easily, the shortcomings such as noise is large, and the revolution sideshake is large, and working life is not long.
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 compact structure, heat radiation evenly, vibration is little, noise is little, the horizontal cycloidal planetary gear speed reducer of long service life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of horizontal cycloidal planetary gear speed reducer, comprise the speed reducer body, output shaft, cycloid wheel and center pivoted arm, described speed reducer body has support and pin wheel housing, support and pin wheel housing connect by stay bolt, described output shaft connects by drive plate with cycloid wheel, offer the pin shaft hole that press-fits bearing pin on the drive plate, has band stop ring selfaligning roller bearing on the output shaft, cycloid wheel offers endoporus, on the pivoted arm of described center cylindrical roller bearing is installed, the endoporus of cycloid wheel matches with cylindrical roller bearing, and the output terminal of described speed reducer body also is provided with retaining ring and rotary dual-oil seal outward successively.
Be provided with the needle pin that meshes with cycloid wheel in the described speed reducer body, transmission is stable.
The beneficial effects of the utility model are: the utility model output shaft and cycloid wheel adopt drive plate bearing pin pattern joint transmission, and cycloid wheel adopts the axial float design, radially by with pin wheel housing on fixing needle pin mesh transmitting torque; Output terminal adopts rotary dual-oil seal to add the retaining ring mode and seals, and changes convenient easy to maintenance.
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. output shaft, 2. cycloid wheel, 3. center pivoted arm, 4. support, 5. pin wheel housing, 6. bearing pin, 7. band stop ring selfaligning roller bearing, 8. retaining ring, 9. rotary dual-oil seal, 10. needle pin.
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.
Horizontal cycloidal planetary gear speed reducer as shown in Figure 1, comprise the speed reducer body, output shaft 1, cycloid wheel 2 and center pivoted arm 3, the speed reducer body has support 4 and pin wheel housing 5, support 4 and pin wheel housing 5 connect by stay bolt, output shaft 1 and cycloid wheel 2 connect by drive plate, offer the pin shaft hole that press-fits bearing pin 6 on the drive plate, has band stop ring selfaligning roller bearing 7 on the output shaft 1, cycloid wheel 2 offers endoporus, on the center pivoted arm 3 cylindrical roller bearing is installed, the endoporus of cycloid wheel 2 matches with cylindrical roller bearing, and the output terminal of speed reducer body also is provided with retaining ring 8 and rotary dual-oil seal 9 outward successively.
Be provided with the needle pin 10 that meshes with cycloid wheel 2 in the speed reducer body, transmission is stable.
On the center pivoted arm 3 cylindrical roller bearing is installed, can be born large radial force and driven loads, cycloid wheel 2 endoporus cooperate with cylindrical roller bearing after installing, and do bearing outer ring and use.Output shaft 1 upper bearing (metal) adopts band stop ring selfaligning roller bearing 7, can bear large load and radial force, is with simultaneously stop ring selfaligning roller bearing 7 that output shaft 1 and support 4 are reached the axially locating effect.
The output terminal of speed reducer body also is provided with retaining ring 8 and rotary dual-oil seal 9 outward successively.Retaining ring 8 surface hardnesses are high, and are more wear-resisting, can directly change if any damage after long-term the use simultaneously, and need not change output shaft 1, saved maintenance cost.
In addition, low density lubricant oil is preferably adopted in the lubricated outer oil bath type of employing of speed reducer and splash system lubrication, and thermal diffusivity is simultaneously lubricants capacity saving well.
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.
