The novel speed reducer is characterized in that a low-speed gear shaft is sleeved with a bevel gear in the vertical direction, a low-speed big gear wheel is further arranged in a machine shell, the low-speed big gear wheel is horizontally meshed with the low-speed gear shaft, the low-speed big gear wheel conducts outputting through an output shaft, a deep groove ball bearing is arranged on the output shaft and arranged between the output shaft and an outer shell in a sleeved mode, and a thrust self-aligning roller bearing is arranged between the deep groove ball bearing and the low-speed big gear wheel. The loading capacity of the speed reducer is effectively improved, and the leak tightness is improved.
Description
Technical field
The utility model relates to a kind of reducing gear, is specifically related to a kind of Novel speed reducer.
Background technique
Speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, and the winding number of motor (motor) is decelerated to desired winding number, and obtains the mechanism of larger torque.For the mechanism of transferring power and motion, the application area of speed reducer is quite extensive at present.Almost in the transmission system of various machinery, can see its trace, from the boats and ships of the traffic tool, automobile, locomotive, heavy machinery for building, the machining machine and tool that mechanical industry is used and automated production equipment, to common household electrical appliances in daily life, clock and watch etc.Its application is from the transmission work of large power, and to little load, angle transmission accurately can be seen the application of speed reducer, and on commercial Application, speed reducer has deceleration and increases torque functions, therefore is widely used in the conversion equipment of speed and moment of torsion.
Existing speed reducer load-carrying ability has certain restriction, and tracing it to its cause is because the bearing load on axle is limited in one's ability, in case transship, the bearing often destroyed at first.
The model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of Novel speed reducer, has mainly solved the limited problem of existing speed reducer load-carrying ability.
The technological scheme that the utility model adopts is: a kind of Novel speed reducer, comprise casing, be arranged on the umbrella gear of two Vertical Meshing in described casing, and the umbrella gear of substantially horizontal is inputted by input shaft, the umbrella gear of described vertical direction is enclosed within on the low speed gear axle, in described casing, also be provided with the low speed gearwheel, described low speed gearwheel and the engagement of low speed gear axle level; Described low speed gearwheel is exported by output shaft, and this output shaft is provided with deep groove ball bearing, and deep groove ball bearing is enclosed between output shaft and shell; Between described deep groove ball bearing and low speed gearwheel, be provided with self-aligning thrust roller bearing.
Between described deep groove ball bearing and self-aligning thrust roller bearing, be provided with adjustment ring.
Between described output shaft and input shaft and shell, be provided with seal ring, sealing circle middle part is provided with circular groove, and described circular groove makes seal ring inboard for barb-shaped, and output shaft and input shaft are close in inboard.
Described seal ring is bolted on casing.
The beneficial effects of the utility model are: owing to taking technique scheme, effectively improved the load-carrying ability of this speed reducer, and improved sealing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A place enlarged view in Fig. 1.
In figure 1, casing; 2, umbrella gear; 3, input shaft; 4, low speed gear axle; 5, low speed gearwheel; 6, output shaft; 7, deep groove ball bearing; 8, self-aligning thrust roller bearing; 9, adjustment ring; 10, seal ring; 11, circular groove; 12, bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1 with Figure 2, a kind of Novel speed reducer, comprise casing 1, be arranged on the umbrella gear 2 of two Vertical Meshing in described casing, and the umbrella gear 2 of substantially horizontal is by input shaft 3 inputs, the umbrella gear 2 of described vertical direction is enclosed within on low speed gear axle 4, in described casing 1, also be provided with low speed gearwheel 5, described low speed gearwheel 5 and the 4 level engagements of low speed gear axle; Described low speed gearwheel 5 is by output shaft 6 outputs, and this output shaft 6 is provided with deep groove ball bearing 7, and deep groove ball bearing 7 is enclosed between output shaft 6 and shell 1; Between described deep groove ball bearing 7 and low speed gearwheel 5, be provided with self-aligning thrust roller bearing 8.
Input shaft 3 is by driven by motor, umbrella gear 2 by two Vertical Meshing, be delivered on low speed gear axle 4, by the level engagement of low speed gearwheel 5 with low speed gear axle 4, transmission of power is to low speed gearwheel 5, finally again by output shaft 6 outputs again, because the low speed gearwheel 5 be connected with output shaft 6 is larger than umbrella gear 2 diameters that are connected with input shaft 3, rotating speed is just low, so after by a series of transmission, slowing down, the moment of torsion of output has just increased greatly.
Deep groove ball bearing 7 on output shaft 6, can increase the load-carrying ability of this speed reducer with 8 while of self-aligning thrust roller bearing engage sleeves greatly, has improved working life.
Between described deep groove ball bearing 7 and self-aligning thrust roller bearing 8, be provided with adjustment ring 9.Adjustment ring 9 is set is in order when deep groove ball bearing 7, during not in correct position, to adjust very easily the position of two bearings with self-aligning thrust roller bearing 8.
Between described output shaft 6 and input shaft 3 and shell 1, be provided with seal ring 10, sealing circle 10 middle parts are provided with circular groove 11, and described circular groove 11 makes seal ring 10 inboard for barb-shaped, and output shaft 6 and input shaft 3 are close in inboard.When the oil pressure of inner room was larger, the inboard of seal ring 5 also can more compress output shaft 3 and input shaft 4 like this, and sealing effect can be better.
Described seal ring 10 is fixed on casing 1 by bolt 12.Can certainly adopt pin or other means of fixation to be fixed on casing, the utility model preferred bolt is fixed.
Every technician's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this model utility; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
