Abstract

The utility model discloses a manual turning gear of a gearless traction machine, which comprises a pinion and a large gear ring corresponding to the pinion. The pinion is connected with a turning gear hand-wheel, the large gear ring is connected with a rotor of the elevator traction machine, the pinion is fixedly sleeved on the a connecting shaft, the tip of the connecting shaft is inserted into a traction machine case, the root of the connecting shaft is connected with the turning gear hand-wheel, the traction machine case is internally provided with a positioning groove for positioning the tip of the connecting shaft, and a positioning hole for positioning the root of the connecting shaft is arranged on the traction machine case. During using, the pinion of the manual turning gear is accurately positioned by the root and the tip of the connecting shaft, thereby guaranteeing the pinion and the large gear ring to be meshed correctly, the left side and the right side of the gear portion of the pinion are symmetrically disposed, thereby ensuring uniform force to the pinion and effectively increasing the reliability of the turning gear.

Description

The hand turning gear of gearless machine
Technical field
The utility model relates to a kind of hand turning gear of gearless machine, belongs to the technical field of elevator.
Background technology
The elevator traction machine hand turning gear is in emergency or need cuts off the power supply when maintenance to elevator, by manually coming the operating mechanism of moving elevator car.Along with elevator technology is growing, gearless machine replaces geared machine gradually at present, this mainly is because with respect to geared machine, gearless machine does not have drop-gear box as the intermediate drive link, so have that driving efficiency height, noise are little, a stable drive and volume is little, simple in structure, advantage such as environmental protection more.Geared machine is rotatably installed in the handwheel of towing machine speed end when meeting an urgent need, overhauling and safeguarding, make the elevator up-and-down movement.Yet, gearless machine, then moves when being mounted with the car of rated weight if still adopt traditional barring structure owing to cancelled mechanical reduction gear, required operating effort far surpasses 400N, can't satisfy national elevator standard and realize the requirement of elevator emergency state of operation with manpower.
For solving above-mentioned difficulties, the hand turning gear of existing gearless machine all is equipped with force amplificatory structure usually, and this force amplificatory structure can be gear engagement mechanism, pulley mechanism etc.For example application number is the Chinese utility model patent " hand turning gear of gearless machine " of CN02217935.6, disclose a kind of hand turning gear, it can directly intermesh from the insertion of the towing machine back shroud outside miniature gears and realize manual jiggering with big gear wheel.Each manufacturing enterprise in actual applications, the structure of hand turning gear has multiple, however existing hand turning gear exists usually that the turning gear installing and locating is inaccurate, easily produce the not high problem of jiggering reliability such as rock during jiggering.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the existing not high problem of hand turning gear jiggering reliability, and a kind of hand turning gear with high reliability is provided.
The technical scheme that the utility model adopted is: a kind of hand turning gear of gearless machine, be arranged on the towing machine casing, described hand turning gear comprises miniature gears, the bull gear corresponding with described miniature gears, described miniature gears is connected with handwheel, described bull gear is connected with the rotor of elevator traction machine, described miniature gears fixed cover is located on the adapter shaft, the taper of described adapter shaft inserts in the described towing machine casing, the root of described adapter shaft is connected with described handwheel, offer the positioning groove of the taper that is used to locate described adapter shaft in the described towing machine casing, and also offer the knock hole of the root that is used to locate described adapter shaft on the described towing machine casing.
The root of described adapter shaft also is arranged with locating bush, and the knock hole of offering on the external peripheral surface of described locating bush and the towing machine casing matches.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage: this hand turning gear in use, root and taper by adapter shaft are accurately located miniature gears, guarantee miniature gears and bull gear correct engagement, and the left and right sides of the wheel toothed portion of miniature gears forms symmetrical expression and arranges, miniature gears is stressed more even when making jiggering, has improved the reliability of jiggering effectively.
Description of drawings
Fig. 1 is the complete section figure of hand turning gear;
Wherein: 1, rotor, 2, bull gear, 3, miniature gears, 31, adapter shaft, 4, locating bush, 7, handwheel, 8, the towing machine casing.
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing and concrete embodiment: referring to Fig. 1, a kind of hand turning gear of gearless machine is arranged on the towing machine casing 8.Hand turning gear of the present utility model comprise miniature gears 3, with the bull gear 2 of described miniature gears 3 corresponding settings, described miniature gears 3 is connected with handwheel 7, described bull gear 2 is connected with the rotor 1 of towing machine, and described rotor 1 is connected with the traction sheave of elevator traction machine.Known technology as mechanical field, will be understood that bull gear 2 can adopt various connection modes to be connected with rotor 1, for example by the connection of key or directly with bull gear 2 processing on rotor 1, can also substitute the mode etc. of bull gear 2 certainly with big gear wheel.
Described miniature gears 3 and an adapter shaft 31 one-shot formings, be wholely set, the taper of described adapter shaft 31 inserts in the described towing machine casing 8, the root of described adapter shaft 31 is connected with described handwheel 7, and the root of described adapter shaft 31 also is arranged with locating bush 4.Offer the positioning groove of the taper that is used to locate described adapter shaft 31 in the described towing machine casing 8, also offer the knock hole that is used to locate described locating bush 4 on the described towing machine casing 8.When hand turning gear is in the jiggering state, described positioning groove cooperates with the taper of adapter shaft 31, described knock hole cooperates with the external peripheral surface of locating bush 4, miniature gears 3 is formed symmetric support, thereby make miniature gears 3 evenly stressed, and miniature gears 3 accurately cooperates mutually with bull gear 2, the fit system of the two can be engagement, strap drive etc., does not limit.
