Abstract
The utility model provides a novel reducer, which comprises a main case, wherein an input connecting shaft end is disposed on one side of the main case; the input connecting shaft end is connected to an input shaft inside the main case; the input shaft is engaged with a main reduction wheel; a transmission bevel gear is disposed on the main reduction wheel; the transmission bevel gear is engaged with a driven bevel gear; the driven bevel gear is connected to an output gear outside the main case; the main reduction wheel and the driven bevel gear are respectively fixed to the main case by a horizontal-push bearing; and an NIMO steel layer with a carburization technology is disposed on outer surfaces of the input shaft, the main reduction wheel, the transmission bevel gear and the driven bevel gear. The novel reducer in the utility model has the beneficial effect that problems such as abrasion, noise and oil leakage caused by gear shape limitation and long-term use are avoided, cost is reduced, the noise is decreased, installation is convenient and adjustment is convenient, etc.
Description
(1) technical field
The utility model relates to a kind of lift special reduction gear, particularly relates to a kind of Novel speed reducer.
(2) background technique
Speed reducer is generally used for the transmission device of low rotation speed large torque, motor, internal-combustion engine or other power running up reach the object of deceleration by the gearwheel on the few gear engagement output shaft of the number of teeth on the input shaft of speed reducer, worm decelerating machine and worm-gear speed reducer do not have great difference in fact, all formed by worm gear and worm screw, but worm decelerating machine is more slightly made, do not have the precision of worm-gear speed reducer good, just large than worm-gear speed reducer of the torsion of the worm decelerating machine of same specification, existing lift special reduction gear adopts adjustable axle to honour gear and is fixed, this adjustable bearing is because the restriction of the form of gear tooth makes gear adjust difficulty, inconvenience is installed, long-term use causes wearing and tearing and causes noise large.Therefore, be necessary existing lift special reduction gear to improve, make it make gear into NIMO steel, adopt carburizing quenching process, change original nitridation process, increase hardness and wear resistance, solve and adopt the cost of nitridation process steel high, the shortcoming wearing no resistance, makes adjustable bearing into horizontal sliding bearing, realized easy to adjust, reduce noise and reducing production costs.
(3) model utility content
In order to overcome the deficiency of existing lift special reduction gear, the utility model provides a kind of Novel speed reducer.
The technical solution of the utility model is achieved in that
A kind of Novel speed reducer of this programme, comprises main case, and a side of described main case is provided with input connecting shaft end; Described input connecting shaft end is connected with the input shaft in main case; Described input shaft is meshed with main ratio wheel; On described main ratio wheel, be provided with transmission umbrella gear; Described transmission umbrella gear is meshed with driven bevel pinion; Described driven bevel pinion is connected with the output gear of main case outside; Described main ratio wheel and driven bevel pinion fix by horizontal sliding bearing and main case respectively.
Further, the outer surface of described input shaft, main ratio wheel, transmission umbrella gear and driven bevel pinion is provided with the NIMO steel layer that adopts carburization process.
Usefulness of the present utility model is: avoided, because the problems such as wearing and tearing, noise and the leakage of oil that profile of tooth restriction occurs with long-term use have realized reducing costs, reducing noise, installation is convenient, easy to adjust etc.
(4) accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-main case, 21-transmission umbrella gear, 22-driven bevel pinion, 3-output bevel gear, 4-input connecting shaft end, the main ratio wheel of 5-, 6-horizontal sliding bearing, 7-input shaft.
(5) embodiment
Below in conjunction with accompanying drawing, a kind of mode of execution of the present utility model is made to brief description.
As a kind of Novel speed reducer of Fig. 1, comprise main case 1, a side of described main case 1 is provided with input connecting shaft end 4; Described input connecting shaft end 4 is connected with the input shaft 7 in main case 1; Described input shaft 7 is meshed with main ratio wheel 5; On described main ratio wheel 5, be provided with transmission umbrella gear 21; Described transmission umbrella gear 21 is meshed with driven bevel pinion 22; Described driven bevel pinion 22 is connected with the output gear 3 of main case 1 outside; Described main ratio wheel 5 and driven bevel pinion 22 fix by horizontal sliding bearing 6 and main case 1 respectively; The outer surface of described input shaft 7, main ratio wheel 5, transmission umbrella gear 21 and driven bevel pinion 22 is provided with the NIMO steel layer that adopts carburization process.
The working procedure of this example: in the time that use is of the present utility model, first, external motor is connected with main case 1 by input connecting shaft end 4, and power transfers to main ratio wheel 5 by input shaft 7; Then, the transmission umbrella gear 21 on main ratio wheel 5 by power transmission to driven bevel pinion 22; By the engagement of transmission umbrella gear 21 and driven bevel pinion 22, power has been realized deceleration and break-in, and last, power spreads out of by the output gear 3 being connected with driven bevel pinion 22.Owing to gear being made into NIMO steel, adopt carburizing quenching process, change original nitridation process, increase hardness and wear resistance, solve and adopt the cost of nitridation process steel high, the shortcoming wearing no resistance, make adjustable bearing into horizontal sliding bearing, realized easy to adjust and minimizing noise.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
