Description

Gearmotor

The utility model belongs to the gearmotor class, specifically is a kind of gearmotor with general coupling arrangement.

The gearmotor of each manufacturer production of present China, mostly be to adopt by on motor reel, processing keyway, with positioning key and clamp nut definite purpose motor and gear reduction unit directly are connected as one, the definite purpose motor price is higher than general purpose motor far away, and the motor of equal-wattage needs corresponding change end face to connect the seam flange size, just can match with the gear reduction unit of different model, this certainly will increase the quantity of motor field frame blank, the versatility difference has influenced the batch process of definite purpose motor, and the original equipment manufacturer daily life of a family influences manufacturing schedule because of the definite purpose motor that can not in time obtain required specification, processing keyway difficulty is bigger on the motor shaft of motor special in addition, cost is higher, gearmotor often is in two-way startup, in the operating mode that load transfinites, so also exist clamp nut easily loosening, key or keyway damage are serious, the defective that failure rate is higher has increased use cost.

It is a kind of simple and compact for structure that the purpose of this utility model is to provide, and is easy to safeguard that versatility is good, is easy to processing, gearmotor with low cost, reliable.

The utility model is achieved through the following technical solutions:

Be a kind of gearmotor, comprise decelerator and motor, it is characterized in that decelerator and motor combine as a whole by the end cap that is processed with the shaft coupling through hole, motor reel is installed in the through hole, and connects with first driving gear of decelerator.

Described decelerator first driving gear connects for be processed with the through hole of band groove at the gear face end face with motor shaft, motor shaft be with through hole accordingly with the structure of boss, motor shaft sleeve is contained in the through hole, the motor shaft processing circlip groove that the ring through hole is outer, and card is put shaft block ring in the circlip groove.

Described decelerator first driving gear is the shaft coupling that is processed with the band boss at the end face of gear with connecting of motor shaft, motor shaft is processed with blind hole, be processed with and boss shape corresponding grooves in the blind bore end both sides, the boss card is placed in the groove on the motor shaft, both constitute a cylinder, the relevant position processing circlip groove of ring boss groove, card is put shaft block ring in the circlip groove.

According to the condition of production of reality, when decelerator first driving gear is enough big, can adopt the version of the through hole of processing belt groove on gear; When decelerator first driving gear less, when being difficult on gear, process through hole, can adopt another kind version of the blind hole of processing belt groove on motor shaft to realize that decelerator driving gear and the connection that has changed above-mentioned straight end-face key connecting of motor shaft into have improved impact resistance.

The utility model compared with prior art owing to installed the end cap that independently can connect with general-purpose machine additional at decelerator and motor union end, both connections employing is the mode of the concave, convex groove connection of Fast Installation mutually, so have the following advantages:

1, simple and compact for structure, be easy to safeguard that versatility is good.

2, be easy to processing, the precision height, shock resistance, with low cost, reliable.

Describe in further detail below in conjunction with accompanying drawing.

Figure 10: prior art example structure schematic diagram.

Among the figure: 1 decelerator, 2 shaft block rings, 3 gears, 4 motor shafts, 5 end caps, 6 motor, 7 through holes, 8 shaft couplings, 9 circlip grooves, 10 motor shafts (band boss), 11 grooves, 12 clamp nuts, 13 positioning keys

As shown in Figure 1, this gearmotor comprises decelerator 1 and motor 6, and decelerator 1 combines as a whole by the end cap 5 that is processed with the shaft coupling through hole with motor 6, and motor reel 4 is installed in the through hole, and connects with first driving gear 3 of decelerator.

Described decelerator first driving gear 3 connects for be processed with the through hole 7 of band groove at the gear face end face with motor shaft 4, motor shaft be with through hole accordingly with the structure of boss, motor shaft sleeve is contained in the through hole 7, the motor shaft 4 processing circlip grooves 9 that the ring through hole is outer, card is put shaft block ring 2 in the circlip groove 9.

Described decelerator first driving gear 3 is the shaft coupling 8 that is processed with the band boss at the end face of gear with connecting of motor shaft 4, motor shaft is processed with blind hole, be processed with and boss shape corresponding grooves 11 in the blind bore end both sides, the boss card is placed in the groove 11 on the motor shaft, both constitute a cylinder, the relevant position processing circlip groove 9 of ring boss groove, card is put shaft block ring 2 in the circlip groove 9.

When first driving gear of decelerator less, in the time of can't processing through hole, also can adopt another embodiment of constructed scheme, promptly be processed with the shaft coupling 8 of band boss at the end face of decelerator 1 first driving gear, motor shaft 4 is processed with blind hole, is processed with in the blind bore end both sides and boss shape corresponding grooves 11, the boss card is placed in the groove 11 on the motor shaft, both constitute a cylinder, the relevant position processing circlip groove 9 of ring boss and groove, and card is put shaft block ring 2 in the circlip groove 9.

In use, as shown in Figure 1, when first driving gear of decelerator 1 is enough big, the version of through hole is processed in employing on gear, because of being processed with the through hole 7 of band boss on decelerator 1 first driving gear, no matter the general-purpose machine of what specification, as long as motor shaft 4 is and through hole 3 corresponding shapes (as Fig. 2～5), both are fastened closely, and card is put spacing shaft block ring 2 in the circlip groove 9 of motor shaft 4 ends, promptly normal the use, because connecting by key connecting of the gear of decelerator 1 and motor shaft 4 changes draw bail with concavo-convex shaft coupling into, thus thoroughly solved as shown in figure 10, because of the frequent positive and negative two-way startup of motor, clamp nut 12 is easily loosening in the operating mode that load transfinites, key 13 or keyway easy damaged cause the problem that shortens in decelerator useful life; When first driving gear of decelerator 1 less, in the time of can't processing through hole, also can adopt identical technical scheme, processing blind hole and on motor shaft 4 with the version (as Fig. 6～9) of groove 11, both correspondences are linked together, and it is spacing with spacing shaft block ring in circlip groove 9, its working method and effect are same as described above, adopt above-mentioned two kinds of execution modes, compare, realized connecting of decelerator and general-purpose machine with traditional decelerator, must supporting motor special and no longer use, also be convenient to simultaneously safeguard, maintenance is compared the structure that adopts shaft coupling to connect with traditional singly-bound connection, intensity and precision have not only been improved, and processing technology is simple, and cost is low, has strengthened reliability of operation.
