Abstract
The utility model discloses a mining explosion-proof permanent magnet electric locomotive first-transmission traveling device. The device comprises wheel sets, a gearwheel, a pinion, a permanent magnet synchronous motor and bearing blocks, wherein the gearwheels are arranged on the wheel sets through bolts or pressing; the pinion is assembled to a shaft head of the permanent magnet synchronous motor through a flat key; the permanent magnet synchronous motor is arranged on the wheel sets in a journal sticking form; the permanent magnet synchronous motor transmits torque to the wheel sets by the gearwheel and the pinion; the bearing blocks are assembled at two ends of the wheel sets through bearings. By adopting a first-stage transmission mode, the device has the advantages of small size, simple structure and high transmission efficiency.
Description
Technical field
The utility model relates to a kind of electric locomotive running gear, relates in particular to a kind of mining explosion-proof type Permanent Magnet and Electric locomotive one-level transmission running gear.
Background technology
The electric explosion-tested locomotive that colliery is used at present has two kinds substantially: the first is direct-current electric locomotive, the electrical motor of this kind of electric locomotive running gear use is DC electromotor with brush, commutate because DC motor adopts brush, commutator, have the shortcomings such as noise is large, fault rate is high, maintaining expense height; Another kind is alternating-current variable frequency power locomotive, this kind of electric locomotive running gear uses AC frequency conversion traction motor, by two-stage gear transmission reducing device, transmission of torque is arrived to electric locomotive wheel pair, this motor speed adjustment poor performance, detent torque are little, this structure exists drop-gear box noise large, the shortcomings such as transmission efficiency is low, and maintenance is inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to maintenance, a kind of mining explosion-proof type Permanent Magnet and Electric locomotive one-level transmission running gear that driving efficiency is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of mining explosion-proof type Permanent Magnet and Electric locomotive one-level transmission running gear, comprise wheel to 1, big gear wheel 2, miniature gears 3, permasyn morot 4, bearing seat 5, described big gear wheel 2 is by bolt or by being press fit into described wheel on 1; Described miniature gears 3 is assembled into by flat key on the spindle nose of described permasyn morot 4; Described permasyn morot 4 is installed to described wheel on 1 with the form of seize; Described permasyn morot 4 is taken turns transmission of torque on 1 to described by miniature gears 3 and big gear wheel 2; Described bearing seat 5 is contained in described two ends of taking turns 1 by bearing set.
The utility model is compared and is had obvious advantage and good effect in prior art: described mining explosion-proof type Permanent Magnet and Electric locomotive one-level transmission running gear adopts permanent magnet synchronous traction motor as propulsion source, compared with traditional DC machine, structurally have simple in structure, easily manufactured, the advantage such as maintenance cost is low; There is space at fit on large, be convenient to the advantage of dismounting and maintenance; In performance, there is tractive force large, the advantage that energy conservation characteristic is good; Permanent magnet synchronous traction motor with the form of seize be installed to wheel to upper and by one-level gear transmission transmission of torque to electric locomotive, running noises is little, driving efficiency is high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described further.
As shown in Figure 1, Fig. 1 is the utility model structural representation.The mining explosion-proof type Permanent Magnet and Electric locomotive one-level transmission running gear of the present embodiment, comprise wheel to 1, big gear wheel 2, miniature gears 3, permasyn morot 4, bearing seat 5.Described big gear wheel 2 is by bolt or by being press fit into described wheel on 1; Described miniature gears 3 is assembled into by flat key on the spindle nose of described permasyn morot 4; Described permasyn morot 4 is installed to described wheel on 1 with the form of seize; Described permasyn morot 4 is taken turns transmission of torque on 1 to described by miniature gears 3 and big gear wheel 2; Described bearing seat 5 is contained in described two ends of taking turns 1 by bearing set.
The mining explosion-proof type Permanent Magnet and Electric locomotive one-level transmission running gear of the present embodiment adopts permanent magnet synchronous traction motor as propulsion source, compared with traditional DC machine, structurally have simple in structure, easily manufactured, the advantage such as maintenance cost is low; There is space at fit on large, be convenient to the advantage of dismounting and maintenance; In performance, there is tractive force large, the advantage that energy conservation characteristic is good; Permanent magnet synchronous traction motor with the form of seize be installed to wheel to upper and by one-level gear transmission transmission of torque to electric locomotive, running noises is little, driving efficiency is high.
The foregoing is only the preferred embodiment of the utility model; not limit practical range of the present utility model with this; all persons that is familiar with technique; use principle of the present utility model and technical characterictic; various changes and the decoration done, within all should being covered by the protection category that these claims define.
