Abstract
The utility model discloses a sprocket output type gearbox, which comprises a box body, wherein a shaft I, a shaft II, a shaft III a shaft V, a shaft VI, and a shaft VII are connected on the box body in parallel, and a main sliding gear is dynamically connected on the shaft I; a first duplex free gear is arranged on the shaft II, a transmission gear is fixedly arranged on the shaft II, and an auxiliary sliding gear is dynamically connected on the shaft II; a second duplex free gear and a third duplex free gear are arranged on the shaft III, and a duplex free gear is arranged on the shaft IV; a main deceleration free gear is arranged on the shaft V, and an auxiliary deceleration free gear is arranged on the shaft VI; and a driver gear is fixedly arranged on the shaft VII , and the two end parts of the shaft VII extending out of the box body are fixedly provided with sprockets. The gearbox with the structure has the advantage of low failure rate.
Description
Technical field
The utility model relates to gearbox, is specifically related to a kind of sprocket wheel output type gearbox.
Background technique
Existing miniature rural area machinery is provided with the transmission shaft that is parallel to each other as the garden management machine in its gearbox, carry out transmission of power by chain and sprocket wheel between four and five.Chain can be elongated in use for some time, easily causes the climbing tooth phenomenon, and the rate of fault height need be opened casing during maintenance, operates very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is at above-mentioned defective, provides a kind of rate of fault low gearbox.
For solving the problems of the technologies described above, the utility model provides a kind of sprocket wheel output type gearbox of following structure, comprises casing, it is characterized in that: be connected with the I axle, II axle, III axle, IV axle, V axle, VI axle and the VII axle that be arranged in parallel on the described casing; Power is connected with main shifting slide gear on the I axle, the free gear of first duplex is housed on the II axle, is fixed with and transmits gear and power is connected with secondary shifting slide gear; Free gear of second duplex and the free gear of the 3rd duplex are housed on the III axle, the duplex free gear that slows down is housed on the IV axle, the main free gear that slows down is housed on the V axle, the secondary free gear that slows down is housed on the VI axle, be fixed with driving gear on the VII axle, the two end part that the VII shaft extension goes out casing respectively are fixed with sprocket wheel.
The gearbox of said structure is compared with existing gearbox, no longer includes chain and sprocket driving chain in it, is gear transmission chain all, has avoided the easy climbing tooth of chain in the existing gearbox and the high rate of fault that causes, therefore the utlity model has the low advantage of rate of fault.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Embodiment
Flange output type gearbox as shown in Figure 1 comprises casing 19, is connected with the I axle 1, II axle 2, III axle 3, IV axle 4, V axle 5, VI axle 6 and the VII axle 7 that be arranged in parallel on the casing 19.I axle 1 is a power input shaft, and the belt wheel 20 that is connected with power plant power is housed on it, goes back power on the I axle 1 and is connected with main shifting slide gear 8; The free gear 9 of first duplex is housed on the II axle 2, is fixed with and transmits gear 10 and power is connected with secondary shifting slide gear 11; Free gear 12 of second duplex and the free gear 13 of the 3rd duplex are housed on the III axle 3, the duplex free gear 14 that slows down is housed on the IV axle 4, the main free gear 15 that slows down is housed on the V axle 5, the secondary free gear 16 that slows down is housed on the VI axle 6, be fixed with driving gear 17 on the VII axle 7, the two end part that VII axle 7 stretches out casing 19 respectively are fixed with sprocket wheel 18.
Above-mentioned main shifting slide gear 8 can mesh with a connection 91 of the free gear 9 of first duplex, can mesh with transmission gear 10 again; A connection 121 engagement often of the free gear 12 of another connection 92 and second duplex of the free gear 9 of first duplex; Transmit another connection 122 engagement often of gear 10 and the free gear 12 of second duplex; Secondary shifting slide gear 11 can mesh with a connection 131 of the free gear 13 of the 3rd duplex, again can with duplex one of free gear 14 connection 141 engagements of slowing down, a slow down connection 141 of free gear 14 of another connection 132 and the duplex of the free gear 13 of the 3rd duplex often meshes; Duplex slow down another connection 142 and main free gear 15 engagements of slowing down of free gear 14; Main slow down free gear 15 and secondary free gear 16 engagements of slowing down; Secondary slow down free gear 16 and driving gear 17 engagements.
The implication of free gear described in the utility model is freely to rotate around its assembled shaft, the implication of described shifting slide gear be can along its assembled shaft slide and with the dynamic annexation of its assembled shaft.
The utlity model has two forward gearss and two and retreat shelves, its drive path following (Arabic numerals are the gear numbering in the accompanying drawing):
Advance: the I shelves: 8 → 10 11 → 141 142 → 15 15 → 16 16 → 17.
II shelves: 8 → 91 92 → 121 122 → 10 11 → 141 142 → 15 15 → 16 16 → 17.
Retreat: the I shelves: 8 → 10 11 → 131 132 → 141 142 → 15 15 → 16 16 → 17.
II shelves: 8 → 91 92 → 121 122 → 10 11 → 131 132 → 141 142 → 15 15 → 16
16→17。
Gearbox provided by the utility model, decapacitation are used for also can be used on the small engineering machinery vehicles such as small sized loader, tractor, road roller and fork truck outside the machinery of miniature rural area.
