Description
Technical field
The utility model relates to the drive unit field, is specially a kind of driving tooth case of toy car mould.
Background technology
At present; Driving mechanism (motor), transmission mechanism that the tooth case of general car mould is placed by housing and enclosure interior constitute; Its housing is divided into upper and lower casing or is divided into left and right housing with the center transmission shaft line of vertical (axially), and housing mainly is the package body as the hollow of driving mechanism and transmission mechanism.Though the transmission of housing and driving mechanism or transmission mechanism has no relation; But the assembling of housing is influential to the driving mechanism of inside and the location of transmission mechanism, such as, because housing is when screwing the hole; The inaccurate situation in location can appear; Therefore housing assembling back is easy of the inequality of exerting oneself makes driving mechanism and transmission mechanism distortion and displacement, thereby causes gear centre apart from diminishing or becoming greatly, causes the main shaft imbalance.If gear centre is apart from diminishing, tooth and tooth interlock tension, resistance cause too greatly that motor load increases the weight of, electric current causes temperature rise greatly, thus the life-span of shortening motor and battery; If gear centre is apart from becoming big, tooth and tooth interlock are loose excessively, thereby cause problems such as noise is big.Yet main shaft is uneven, and trailing wheel will be uneven, and car load also can be uneven, and the turning of car mould is spinned easily and overturned.
The utility model content
In order to solve the problem that prior art exists, the utility model to overcome the tooth tank current big, noise is big, spins and problem such as overturning, drives the tooth box structure thereby designed brand-new car mould.
The utility model is achieved in that a kind of car mould drives the tooth case; Form by housing, motor and transmission mechanism; Transmission mechanism is made up of motor gear, transition axis, transition gear, driving shaft and driven wheel; The serve as reasons two-layer at least housing of laterally (radially) of said housing constitutes, and all offers hole that the axle that supplies transmission mechanism passes or the fixing groove of axle that supplies transmission mechanism on every layer of housing.
Further, said housing is a three-decker, is that protecgulum, middle level are that middle cover and lower floor are that bonnet constitutes by the upper strata.
Place motor between said middle cover and the bonnet, the bottom of said bonnet is provided with the seat hole and the lower shaft hole that supplies driving shaft to penetrate that is used to place motor, and said middle cover offers the motor axis hole that places motor output shaft;
Place the gear train of transmission mechanism between said middle cover and the protecgulum, said middle cover is provided with the axial trough of the transition axis that is used to plant, and said middle cover offers the central axis hole that supplies driving shaft to pass, and said protecgulum offers the upper shaft hole that supplies driving shaft to pass.
Said bonnet be provided with the axle sleeve groove and on the axle sleeve groove setting-in convex axle sleeve, said axle sleeve groove offers axle sleeve hole, said axle sleeve hole is concentric with lower shaft hole.
Said upper shaft hole setting-in has the circle cover of trepanning, and said trepanning is concentric with upper shaft hole, and said driving shaft is upward through round trepanning.
Said upper shaft hole is embedded with bearing.Said central axis hole is embedded with bearing.Said lower shaft hole is embedded with bearing.
The utility model is broken through traditional tooth box structure, changes laterally (radially) assembling into by traditional vertical (axially) assembling, and the axle part of transmission mechanism is assemblied in the hole behind protecgulum, middle cover and the bonnet of housing; Make that centre-to-centre spacing fixedly remains unchanged between the gear that is placed on the axle, gear drive is steady, and electric current is reduced; Noise reduces; The main shaft balance, car can keep balance when turning, be difficult for spinning and overturning.

Fig. 1 is the explosive view that the car mould drives the tooth case;
Fig. 2 is the explosive view of housing;
Fig. 3 is the installation diagram that the car mould drives the tooth case.
Wherein, 1-protecgulum, 2-middle cover, 3-bonnet, 4-motor, 5-motor gear; The 6-driven wheel, 7-transition gear, 8-circle cover, 9-convex axle sleeve, 10-driving shaft, 11-transition axis; 12-seat hole, 13-motor axis hole, 14-axle sleeve groove, 15-axle sleeve hole, 16-lower shaft hole; The 17-central axis hole, 18-upper shaft hole, 19-axial trough, 20-motor output shaft, 21-circle trepanning
Below in conjunction with accompanying drawing and specific embodiment the utility model is carried out detailed explanation.
The specific embodiment
The utility model is that a kind of car mould drives the tooth case, and is as shown in Figure 1, is made up of housing, motor 4, transmission mechanism.Housing is formed (Fig. 3) by protecgulum 1, middle cover 2 and bonnet 3 these three layers of housings, and they are horizontally set separately, and promptly their plane separately and transmission mechanism is axially perpendicular.Transmission mechanism is made up of, motor gear 5, transition axis 11, transition gear 7 (it is made up of concentric gear wheel and pinion), driving shaft 10, driven wheel 6; Motor gear 5 is sleeved on the motor output shaft 20; Transition gear 7 is sleeved on the transition axis 11, and driven wheel 6 is sleeved on the driving shaft 10.The gear wheel of transition gear 7 and motor gear 5 engagements, the pinion of driven wheel 6 and transition gear 7.Protecgulum 1, middle cover 2 and bonnet 3 are through the fixing tooth tank shell of forming of nut.
As shown in Figure 2, bonnet 3 is a hollow cavity, and the bottom of bonnet 3 offers a hole 12, and the bottom of bonnet 3 also offers axle sleeve groove 14 and lower shaft hole 16, offers axle sleeve hole 15 on the convex axle sleeve 9.The bottom of motor 4 protrusions is positioned in the hole 12, and the projection of convex axle sleeve 15 inserts in the axle sleeve groove 14, and axle sleeve hole 15 is concentric with lower shaft hole 16.The lower end of driving shaft 10 is through in axle sleeve hole 15 and the lower shaft hole 16.
Protecgulum 1 offers upper shaft hole 18, and upper shaft hole 18 is embedded with circle cover 8, and circle cover 8 offers round trepanning 21.The upper end of driving shaft 10 is passed in the round trepanning 21.
Protecgulum, middle cover and bonnet superimposed fixing after, two hollow cavities butt joint backs of bonnet 3 and middle cover form the cavity of ccontaining motors 4.The gear of ccontaining transmission mechanism between protecgulum 1 and the middle cover 2.
The utility model; Because the centre-to-centre spacing of transition gear 7, motor gear 5 and driven wheel 6 is always fixed; No matter the housing post-production operation of tooth case has any deviation; Can not make gear centre apart from changing, tooth is always keeping perfectly cooperating with tooth, and the problem that electric current is big or noise is big will be readily solved.Driving shaft 10 is fixed on protecgulum 1, tooth case middle cover 2 and the bonnet 3, and the balance of car integral body is better, and car is difficult for spinning and overturning when turning.
