Abstract
The utility model relates to a reduction gear of a motor, which comprises a gearbox body, an upper cover, a speed reduction sleeve and a connecting rod, wherein the main shaft of the motor is inserted into the middle part of the gearbox body; the speed reduction sleeve and a reducing gear are sleeved on the outer side of the main shaft of the motor; the connecting rod is arranged between the main shaft of the motor and a transmission shaft; a bearing is assembled on the main shaft of the motor; a sealing ring is arranged on the outer ring of the main shaft of the motor; and the upper cover is mounted at the top of the gear box body. The utility model has the benefits that the bearing capacity of a reduction box is greatly enhanced aiming at the work environment of a dock and a harbor particularly; the volume and the weight of the reduction gear are enabled to be reduced greatly by adopting the optimum structural design; the bearing capacity of the reduction box is enhanced; and the reduction gear of the motor can bear 22KW motor input power; and the reduction box has the characteristics of durability, easy maintenance and longer service life and the like.
Description
Technical field
The utility model relates to power transmission mechanism, specifically a kind of motor deceleration device.
Background technique
The velocity transducer of speed reducer general using gear decelerates to desired winding number with the winding number of motor (motor), and obtains the mechanism of big torque; The mechanism that is used for transferring power and motion at present, the application area of speed reducer is quite extensive, from the boats and ships of the traffic tool, automobile, locomotive, used machining machine and tool and the automated production equipment of heavy facility, mechanical industry for building, common household electrical appliances, clock and watch etc. in the daily life all can be widely used in the conversion equipment of speed and moment of torsion.But this wherein exists certain defective, and for example the speed reducer volume is bigger usually and heavier, and a little less than the machine bearing capacity strengthened, the motor input was subjected to certain restriction; In addition, body lack working life, be not durable, easy care not.
The model utility content
At above defective, the utility model provides a kind of simple in structure, volume is less, working life is long motor deceleration device, thereby on the basis of having simplified structure and strengthened the bearing capacity of speed reducer greatly.
For achieving the above object, the utility model is by the following technical solutions:
A kind of motor deceleration device comprises casing, loam cake, deceleration cover and connecting rod, and the middle part of casing penetrates electric machine main shaft, the described electric machine main shaft outside is with slow down cover and reducing gear, between electric machine main shaft and the transmission shaft connecting rod is set, is furnished with bearing on the described electric machine main shaft, its outer ring is provided with seal ring; Loam cake is installed at the top of described casing.
The beneficial effect of motor deceleration device described in the utility model is: especially at the port and pier working environment, strengthened the bearing capacity of speed reducer greatly; By adopting Optimal Structure Designing that its volume and weight are dwindled greatly; The speed reducer bearing capacity strengthens, and can bear the 22kw power input to machine; That speed reducer has is durable, easy care, working life long characteristics.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described motor deceleration device of the utility model embodiment;
Fig. 2 is the side view of the described motor deceleration device of the utility model embodiment.
Among the figure:
1, casing; 2, loam cake; 3, electric machine main shaft; 4, deceleration cover; 5, transmission shaft; 6, fixing bolt; 7, connecting rod; 8, reducing gear; 9, bearing; 10, seal ring.
Embodiment
Shown in Fig. 1-2, the described motor deceleration device of the utility model embodiment, comprise casing 1, loam cake 2, deceleration cover 4 and connecting rod 7, the middle part of described casing 1 penetrates electric machine main shaft 3, described electric machine main shaft 3 outsides are with slow down cover 4 and reducing gear 8, connecting rod 7 is set to realize interlock between electric machine main shaft 3 and the transmission shaft 5, is furnished with bearing 9 on the described electric machine main shaft 3, its outer ring is provided with seal ring 10; Loam cake 2 is installed at the top of described casing 1, and casing 1 two ends are fastening by plurality of fixed bolt 6.Can strengthen the bearing capacity of speed reducer greatly at the port and pier working environment; By adopting Optimal Structure Designing that its volume and weight are dwindled greatly; The speed reducer bearing capacity strengthens, and can bear the 22kw power input to machine; That speed reducer has is durable, easy care, working life long characteristics.
