Abstract
The invention discloses a speed changer. The speed changer consists of a gearbox, a motor and a coder, wherein radiators are arranged on at least two sides of the gearbox along the axis direction of an output shaft of the gearbox. The radiators are arranged on the sides of the gearbox, and each radiator consists of an aluminum substrate and radiating fins, so that the speed changer can be effectively radiated when working; and through practice, the temperature of the gearbox is reduced by about 15 degrees, the working temperature of the coder is basically kept in the range of 50 to 55 degrees, and working stability is improved.
Description
Technical field
The present invention relates to a kind of speed changer, the good speed changer of particularly a kind of thermal diffusivity.
Background technology
In the intaglio printing system, the power of galley axle rotation is provided by speed changer, like Fig. 1, shown in Figure 2; Described speed changer is by gearbox 1, and motor 2 is formed with encoder 3, and the output shaft 4 of gearbox 1 is in order to connect the galley axle; Gearbox 1 in normal operation, temperature can be increased to about 75 degree, because gearbox 1 is close together with motor 2; Therefore the temperature of motor 2 also can be elevated to about 65 degree; In like manner, the encoder 3 that is arranged on the motor 2 also can reach about 65 degree, and high like this temperature brings harmful effect can for machine operation stability; Can lose the encoder feedback amount under the serious situation, thereby influence is to the accurate control of print speed printing speed.
Summary of the invention
The present invention has overcome the deficiency that exists in the above-mentioned prior art, provides a kind of thermal diffusivity good, can improve the speed changer of job stability greatly.
Technical scheme of the present invention is achieved in that
A kind of speed changer is by gearbox, and motor and encoder are formed, and along the axis direction of output shaft of gear-box, at least two sides of gearbox, are provided with radiator.
As preferably, described radiator comprises aluminium base, on aluminium base, is provided with fin.
As preferably, described aluminium base is fixed on the gearbox through screw.
As preferably, between aluminium base and gearbox, scribble heat-conducting silicone grease.
As preferably, on 3 sides of gearbox, be provided with radiator.
Adopted the invention has the beneficial effects as follows of technique scheme:
The present invention has installed radiator on the side of gearbox; Radiator is made up of aluminium base and fin; Thereby can when speed changer is worked, effectively dispel the heat to it, through practice, the temperature of gearbox has descended than in the past about 15 degree; The operating temperature of encoder remains essentially between 50～55 degree, has improved job stability.
Description of drawings
Fig. 1 is the structural representation of speed changer in the prior art;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the structural representation of speed changer of the present invention.
The specific embodiment
The specific embodiment of the present invention is following:
Embodiment: a kind of speed changer, as shown in Figure 3, be by gearbox 1, motor 2 is formed with the encoder (not shown), and the axis direction along being parallel to output shaft of gear-box is provided with radiator on end face, left surface and the right flank of gearbox 1; Described radiator comprises aluminium base 5, on aluminium base 5, is provided with fin 6; Between aluminium base 5 and gearbox 1, scribble heat-conducting silicone grease 7, described aluminium base 5 is fixed on the gearbox 1 through screw.
