WP：如何获取特定自定义类型的所有分类法名称

I am trying to get all taxonomy names of a speicific custom type.
In the stackoverflow archive I found the script below for a single postID. I would like to loop all taxonomy names of a single custom post type and not just one with the id.
Taxomy should be: my_tax and the custom post type: my_team

            $terms = get_the_terms( $post->ID, 'my_tax' );
            foreach($terms as $term) {
                echo $term->name;
            }

Such code can be:

$type = 'my_team';
$args = array(
  'post_type' => $type,
  'post_status' => 'publish',
  'posts_per_page' => -1,
);

$my_query = null;
$my_query = new WP_Query($args);
if ($my_query->have_posts()) {
    while ($my_query->have_posts()) {
        $post = $my_query->the_post();
        $terms = get_the_terms( $post->ID, 'my_tax' );
        foreach($terms as $term) {
            echo $term->name;
        }
    }
}
wp_reset_query();  // Restore global post data stomped by the_post().
